Tons of highly radioactive nuclear waste will continued be unsafely stored at U.S. nuclear plants indefinitely unless action is taken to stop this.
The Koeberg nuclear plant in South Africa had a similar container (a waste water tank) crack and leak after only 17 years with cracks deeper (0.61″) than most U.S. thin canisters (0.50″). The tank was at ambient temperature. Cracks grow faster in hotter stainless steel canisters.
The majority of U.S. nuclear power facilities are storing highly radioactive nuclear waste in thin-walled canisters (mostly 1/2″ thick) that both the Nuclear Regulatory Commission (NRC) and the Department of Energy (DOE) admit cannot be inspected (on the outside or inside), cannot be maintained, repaired, and can crack and leak in the short-term. Other countries use thick-walled metal casks 10″ to almost 20″ thick that do not have these problems.
Japan abolished in October 2015 the use of aluminum alloy baskets that hold the fuel assemblies in place inside the casks, stating they may not last even 60 years. Japan’s Nuclear Regulatory Authority (NRA) said the constant heat causes the baskets to degrade more quickly than expected. This model had been adopted in 2007 guidelines. There are 35 of this type of basket employed in Japan (20 at Fukushima Daiichi and 15 at Tokaimura). Out of the 20 at Fukushima, 11 exhibited the problem. More…
U.S thin-walled canister systems also use aluminum alloy baskets. However, because the lids are welded shut no one knows if there are problems. Japan was able to inspect their baskets because the lids of their casks are bolted instead of welded.
There are no adequate plans in place to prevent or remediate a major radiation release from these thin-walled canisters. We will only know of the problem after radiation is released into the environment.
The NRC no longer requires the fuel assemblies to be retrievable from the canisters (ISG-2, Rev. 2), even though the DOE Standard Contract with utilities requires this.
NRC Director Mark Lombard is responsible for approving this change even though he and others know fuel will eventually need to be retrieved from these thin canisters and the canisters cannot currently be inspected or repaired and may crack and leak in short-term storage. Comments to the NRC regarding the impacts of this rule change were dismissed with bureaucratic double talk.
The NRC also allows empty spent fuel pools to be destroyed at decommissioned plants, even though they know this is the only approved method the utilities have to unload failing canisters.
Each canister contains more highly radioactive Cesium-137 than released from Chernobyl.
Even a microscopic through-wall crack will release millions of curies of radiation into the environment states Dr. Kris Singh, President and CEO of Holtec. He said it’s not feasible to repair the cracks even if you could find them.
San Onofre (SONGS) stores 89 times more lethal radiation (Cesium-137) than released from Chernobyl. Currently there are 50 “Chernobyl” cans with only 5/8″ thick steel walls and one can with other high level radioactive waste. They began loading in 2003.
Southern California Edison is ignoring the problems of thin canisters. Instead they plan to buy almost 100 Holtec thin canisters and store them in an experimental unproven system. Cost is estimated at $4 million each, including labor. Edison refuses to disclose the actual cost, even though this is ratepayer money.

A Diablo Canyon canister located in a similar marine environment to the Koeberg tank has all the conditions for cracking in a two-year old canister and crack growth rate will be faster in hotter canisters filled with spent nuclear fuel. EPRI (the utilities research lab) found corrosive salts and a temperature range low enough for salts to dissolve on the canister. No one knows if the Diablo or any other thin canisters are cracking, because they will only know after the canisters leak radiation into the environment. California climate zone data shows both Diablo Canyon (Zone 5) and San Onofre (Zone 7) are located in high moisture zones (with on-shore winds, surf, and frequent fog); enough moisture to dissolve salts on the canisters.
No one can predict when a crack will start, but once a crack starts it can grow through the wall of the canister in less than 5 years, and in some cases less than a year, due to the higher heat level of thin canisters filled with spent nuclear fuel (canister temperatures, e.g., 60º C (140ºF) to 80ºC (176ºF)). This Sandia Lab chart assumes a 5/8″ (0.625″) canister wall thickness of which there are very few that thick in the U.S. Most are 1/2″ thick. It demonstrates hotter containers will have much faster crack growth rate. Draft Geologic Disposal Requirements Basis for STAD Specification, A. Ilgen, C. Bryan, and E. Hardin, Sandia National Laboratories, March 25, 2015, FCRD-NFST-2013-000723 SAND2015-2175R, PDF page 39 and 46 [http://bit.ly/SAND2015-2175R]
The NRC states once a crack starts it can grow through the wall of the canister and leak in about 16 years. Edison has existing canisters that have been loaded since 2003. Southern California Edison plans to continue to unsafely store over 1600 metric tons of highly radioactive nuclear waste on the Southern California coast even though they know all this.
The Nuclear Regulatory Commission (NRC) approves use of these inferior canisters in spite of knowing these problems. Therefore, it is up to our local, state and federal elected officials, regulators and concerned citizens to take action to address these issues before we have major nuclear radiation releases that can create permanent sacrifice zones in our communities, spread highly toxic radiation into our food supply, and disrupt our economy and transport systems.
Each thin canister contains about as much Cesium-137 as was released from Chernobyl.
There is no approved plan to remediate failed canisters once nuclear spent fuel pools are destroyed, as is the plan at San Onofre and other decommissioning nuclear reactors.
Most other countries use thick walled casks (about 10″ to 20″ thick) rather than the mostly 1/2″ thick canisters used in the majority of U.S. nuclear facilities. Thick walled casks do not have the thin canister problems.Most other countries use thick walled casks.
- The two major thick walled storage and transport cask manufacturers are Areva (TN-24 series) and Siempelkamp (e.g., Castor V/19).
- Japan uses the Areva TN-24 thick cask design. Germany uses Castor casks and Areva TN E casks.
- Other countries store their casks in reinforced buildings for additional environmental protection.
- U.S. utilities migrated to thin canisters to save money. However, long term, the thicker casks will likely save money since they do not have the thin canister problems.

San Onofre nuclear reactors have been shutdown since January 31, 2012 and the Nuclear Regulatory Commission (NRC) concluded Southern California Edison was at fault. Therefore, how can we trust them to store the waste safely?
The San Onofre shutdown resulted from decades of excessive wear in both reactors’ (Units 2 and 3) new steam generator tubes, which resulted in a steam generator radiation tube leak on Unit 3 on January 31, 2012. The NRC concluded Edison was at fault: “…a significant design deficiency in replacement steam generators, resulting in rapid tube wear of a type never before seen in recirculating steam generators.” In the NRC’s December 23, 2013 NRC Notice of Violation to Edison, the NRC stated: “…design control measures were not established to provide for verifying or checking the adequacy of certain designs.”
The failed steam generator multi-billion dollar boondoggle is about to be repeated with Edison’s decision to purchase the Holtec HI-STORM UMAX inferior thin canister storage system that may crack within a few years. A system that even Vermont Yankee’s utility, Entergy, considered unproven, too complex and overpriced.
The experience of other facilities substantiates the conclusion that the cost to install an underground dry cask storage system [UMAX] at Vermont Yankee would be considerably more expensive than the above ground HI-STORM 100 system. Additionally, I understand that utilities suing the U.S. Department of Energy (“DOE”) for breach of its contracts to remove spent fuel from their sites are required to take reasonable steps to mitigate the damages incurred as a result of the breach. It is therefore unlikely that the cost of a spent fuel storage system that is significantly more costly than another available alternative can be recovered from DOE. Entergy VY continues to believe that the HI-STORM 100U [UMAX] system not only would be significantly more difficult and substantially more expensive to install than the above-ground HI-STORM 100 system, but also carries significant schedule and cost risks associated with an unproven system.
The UMAX system is even worse than the other thin canister systems. Edison plans to store the system partially underground in moist corrosive soil. The system has air vents in the outer lid to cool the thin hot canisters. However, there are no drains for any moisture, water or debris that enters the vents. Employees are expected to put hoses down the vent holes and pump any water out. Employees will be exposed to radiation coming out of the vent holes, even when the canisters are not leaking from cracks.
All thin canisters can crack, but cannot be inspected, repaired or maintained and have no early warning system prior to a radiation release.
- A Diablo Canyon canister located in a similar marine environment has all the conditions for cracking in a 2-year old canister.
- A similar container at the Koeberg nuclear plant leaked in 17 years.
- San Onofre has 51 existing canisters and began loading them in 2003.
Cracked canisters cannot be transported.
- NRC Regulation 10 CFR § 71.85 Packaging and Transportation of Radioactive Materials. Preliminary determinations. Before the first use of any packaging for the shipment of licensed material — (a) The certificate holder shall ascertain that there are no cracks, pinholes, uncontrolled voids, or other defects that could significantly reduce the effectiveness of the packaging.
- NRC Certificate of Compliance NUHOMS-MP197HB, Certificate 9302, April 23, 2014 (ML14114A099), Page 17, “For any DSC [Dry Storage Canister] that has been used in storage, the condition of the DSC must be evaluated, prior to transportation, to verify that the integrity of the canister is maintained.”
Edison is ignoring this data and plans to purchase a Holtec dry storage system that cannot be inspected, repaired or maintained.
Edison has no plans or funding to deal with leaking or cracking canisters.
Each canister contains more radiation than released from Chernobyl.

The California Coastal Commission voted to approve a 20-year permit to install the experimental unproven Holtec UMAX underground nuclear waste thin canister storage system at San Onofre even though they know the system has problems. Instead they added critical “special conditions” that Edison isn’t required to meet for years and it’s unlikely they can ever meet them. Also, these are unfunded conditions. Edison’s cost estimate to the California Public Utilities Commission assumes nothing will go wrong, so it has no funding to remediate problems or relocate the dry storage system on the property, as required by this Coastal permit.
- Handout: Request Coastal Commission REVOKE Nuclear Storage Permit
- The Commission acknowledged the Holtec system cannot be inspected or maintained. The system is subject to cracking. Cracked canisters cannot be transported. Rather than requiring a system that does not have these critical flaws, they are accepting promises from Edison that these issues will be resolved sometime in the future.
- The Coastal Commission should only approve a permit for a spent nuclear fuel storage system that can be inspected, maintained, monitored and transported.
- If they have the authority to require these conditions in 20 years, they can require them now.
- The Coastal Commission should not lower their standards just because Edison chose an inferior thin canister system that does not meet these critical requirements.
- Thick metal cask storage options are available that meet Coastal Commission requirements now and can be deployed in a reasonable time frame. This is proven technology used throughout the world and in the U.S.
- Summary of Special Conditions:
- Special Condition 2, which authorizes the proposed development for a period of twenty years and requires SCE to return for a CDP Amendment to retain, remove or relocate the ISFSI facility, supported by:
- (i) an alternatives analysis, including locations within the decommissioned Units 2 and 3 area;
- (ii) assessment of coastal hazards and managed retreat;
- (iii) information on the physical condition of the fuel storage casks and a maintenance and monitoring program; and
- (iv) proposed measures to avoid/minimize visual resource impacts.
- Special Condition 7, which requires SCE to submit, as soon as technologically feasible and no later than October 6, 2022, a maintenance and inspection program designed to ensure that the fuel storage casks will remain in a physical condition sufficient to allow both on-site transfer and off-site transport, for the term of the project as authorized under Special Condition 2.
- Special Condition 3, which requires SCE to agree to not enlarge or replace the existing NIA seawall for purposes of protecting the proposed project from coastal hazards.
- Special Conditions 1, 4, 5, and 6 which require evidence of the Applicant’s legal ability to undertake the development as conditioned by the Commission, assumption of risk, liability for attorney’s fees, and restrictions on future development.
- Special Condition 2, which authorizes the proposed development for a period of twenty years and requires SCE to return for a CDP Amendment to retain, remove or relocate the ISFSI facility, supported by:
- Coastal Commission Final Approval Documents
- The Union of Concerned Scientists endorsed the Holtec thin canister system without addressing the critical problems of the system. Holtec UMAX System email exchange with UCS Dave Lochbaum, October 2015
- Email Joseph.Street@coastal.ca.gov to request the permit be revoked.
- The Coastal Commission granted a 20-year permit for a system that cannot be inspected for cracks, cannot be repaired, may crack in 20 years (or sooner for existing thin canisters) and cannot be transported with cracks.
- Tell your local and state elected officials to urge the Governor, the Coastal Commission and the CPUC to NOT allow a nuclear waste storage system to be installed that can crack, that cannot be inspected for cracks, cannot be repaired or maintained and cannot be transported. Tell them to:
- not approve a system based on vaporware — capabilities that do not exist. It is against state government regulations to procure vaporware, so why are we allowing Edison to do this? We’ve had enough broken promises from Edison, the federal government and the nuclear industry, so we should not continue to rely on their promises of future solutions.
- Other options are available now, but Edison refuses to consider them.
- The NRC approves systems for 20 years even though they don’t meet these requirements. However, it is within the states jurisdiction to require a system that is guaranteed to last decades and won’t affect our coastal resources and communities. The NRC would approve such a system, but Edison needs to ask for it.
- Edison should be required to prove they can meet the special conditions prior to the installation of the system, not 20 year later.
- The Coastal Commission included “special conditions” that must be met AFTER 20 years, including ability to inspect, repair, maintain and transport. If they have the authority to include these special conditions now, then they should require them NOW not in 20 years when it’s too late.
- The CPUC will be making a decision on whether to give Edison the almost $1.3 billion of our limited ratepayer trust fund to install and manage this inferior system. Edison’s Tom Palmisano said Edison has no money allocated to relocate this system to higher ground as required by one of the special conditions.
- NRC Director of Spent Fuel Management, Mark Lombard, admitted to the Commissioners there is no technology to inspect or repair these systems now and only offered promises they would figure it out in the future.
- NRC’s Mark Lombard did NOT tell the Coastal Commissioners:
- A 2-year old Diablo Canyon canister has all the conditions for cracking.
- The Koeberg nuclear plant in South Africa had a similar component crack and leak after 17 years, due to coastal conditions (on-shore coastal winds, surf, frequent fog)
- The EPRI report he sited saying there would be no problems for at least 30 years excluded the Diablo Canyon and Koeberg data. EPRI cherry-picked the data in that report, even though the Diablo Canyon data is EPRI data.
- Existing San Onofre thin canisters have been loading since 2003. This means leaks can start in 5 to 8 years.
- The NRC only requires quarterly monitoring for radiation leaks and there is no early warning monitoring technology for thin welded canisters.
- Thick metal casks (10″ to 20″ thick) do not have any of these problems and are transportable so could meet all the Coastal Commission conditions. They can be approved by the NRC if Edison decides to purchase them. Thick casks (Areva TN-24) were used at Fukushima and survived the earthquake and tsunami. The NRC has approved thick casks for storage and transport, such as those at Prairie Island (TN-40). Others in U.S. using thick casks for storage: North Anna (TN-32), McGuire (TN-32), Surry (TN-32, Castor V21 and X33, and Peach Bottom (TN-68).
- The method used to inspect empty thin canisters for cracks (putting a fluid dye inside the canister) will not be one of their solutions. All the other inspection technologies, even if they find a way to do them, will not be sufficiently reliable.
- The Holtec UMAX system approved by the NRC is different than the design planned for San Onofre. However, Lombard said they only plan to review the changes and inspect it after it is built.
- Our decision makers should question the credibility of those who support installation of a system that can crack, that cannot be inspected, repaired, maintained, or transported with cracks, and are willing to recommend vaporware. See Coastal Commission Addendum that includes correspondence from those supporting and opposing this system. Notice the inadequate justification for those that support this system.
- The Coastal Commission staff report identified these critical problems. However, it was clear from the “likely impossible to meet” special conditions and setting the scope of review to only 20 years, that this decision was made above their level.

- Doesn’t mention that even though a NRC general license for the ISFSI site allows them to store fuel without a public hearing and NRC prior approval, they still need a licensed product and must following the technical specifications of that license and perform a site specific analysis. The proposed Holtec UMAX system does not meet NRC approved technical specifications. The NRC plans to inspect the system before fuel is loaded to ensure it complies with the technical specifications — however, this is AFTER it is built. See Holtec UMAX not approved for San Onofre.
Below is the proposed location for the Holtec HI-STORM UMAX thin “underground” spent fuel canister system at San Onofre. Half under ground, and close to the water table and about 100 feet from the ocean. Edison admits the Sea Wall hasn’t been maintained so can’t be counted on for protection. This plan doesn’t meet Coastal Act requirements, but Coastal Commission staff think there are no other options, but there are.
Presentation to the Coastal Commission on why they should deny the Coastal Permit, Donna Gilmore, October 6, 2015
- The Coastal Commission should not approve vaperware (technology that doesn’t exist) nor make decisions based on unsubstantiated hope.
- Coastal Commission staff recommend kicking the can down the road and approving the permit with the condition that Edison will figure out how to inspect, repair and maintain this inferior system after 20 years.
- Would you buy a car that cannot be inspected, maintained, repaired and has no early warning system before the car fails? That is what the Coastal Commission is allowing if they approve this Coastal Development Permit.
- Edison claims they can relocate the system to another spot a few feet away if the coast erodes and the sea rises. That would cost hundreds of millions of dollars with the current Holtec system (it must be rebuilt) and we all know who will pay for that. Edison plans to spend all the Decommission Trust Fund money and they have not allocated any funds for this.
- The Coastal Commission should require Edison have a ready plan for existing canisters that may leak in as little as 5 years and not allow over 20 years before Edison must have an approved plan.
- Thick casks are the solution.
- Thick casks don’t crack and are up to 20″ thick compared to the Holtec thin (5/8″ thick) thin canisters. Edison can choose thick casks, if the Coastal Commission rejects their inadequate application.
- Thick casks are designed for longer term storage and transport and can be inspected, maintained and monitored and have proved reliable for over 40 years.
- Edison refused to allow bids from thick cask vendors. Vendors will not apply for an NRC license unless they have a customer. Edison needs to be that customer.
- Commission staff admit the tons of nuclear waste may be here for decades or longer.
- San Onofre fuel must cool for 25 to 45 years before it can be transported to a permanent repository.
- Proposed consolidated interim sites require federal legislation and funding and have many other obstacles, so it’s critical we have the best available storage technology until the waste can be moved.
- Read and share detailed comments submitted to Coastal Commission.
- Waste storage alternatives exist now that meet Coastal Act requirements DGilmore, October 6, 2015
Why when the Coastal Commissioners know these canisters cannot be inspected and are subject to cracking would they approve a Coastal Permit? Listen to Commissioner Shallenberger grill NRC Director Lombard:
Are California and other U.S. nuclear spent fuel waste canisters cracking?
No one knows because there is no technology to inspect or repair cracks in thin stainless steel canisters filled with spent nuclear fuel waste. (Share handout)
San Onofre canisters could start leaking radiation in 5 years (2020), if San Onofre canisters have a failure similar to a Koeberg nuclear power plant component. San Onofre started loading canisters with spent fuel in 2003.
The Nuclear Regulatory Commission (NRC) reported a similar component at the Koeberg Nuclear Plant cracked and leaked in 17 years. The crack was deeper than the thickness of most U.S. thin canisters. Other factors can also cause canisters to crack and leak. More…
Koeberg is located in a similar corrosive marine environment as San Onofre and Diablo Canyon: on-shore winds, surf and frequent fog. The Koeberg container had cracks up to a depth of 0.61″. The San Onofre canisters are only 0.625″ thick. The canisters at other California locations, such as Diablo Canyon, are even thinner (0.50″). There are over 2000 loaded canisters in the U.S. Most are 1/2″ (0.50″). More…
The President of Holtec, Kris Singh, says it’s not feasible to repair thin steel canisters. He states even a microscopic crack will release millions of curies of radiation into the environment. In addition, the NRC and their concrete experts state the concrete base of underground storage system are at higher risk of failure (due to moisture and soil chemistry) and are challenging to inspect.
Southern California Edison, PG&E and other U.S. utilities have no adequate plans to replace cracked canisters and monitoring system only alerts us after canisters leak radiation into the environment. The only proposed “solution” is to put the cracked canister into a thick cask, with no plan of what to do with it next. There is no NRC approved cask design or procedure for this purpose. It would not solve the problem of needing to replace canisters in case of failure or to meet current Department of Energy (DOE) and Nuclear Regulatory requirements. Cracked canisters are not approved for transport.
Edison plan to spend almost $1.3 billion of ratepayer funds to store and manage 1680 metric tons of San Onofre nuclear waste in thin 5/8” steel canisters that may crack within 20 years after loading. Their $1.3 billion plan assumes no canister will fail. And they want us to buy vaporware — a product with a vendor promise of a future solution for finding and measuring cracks. Even if they manage to find a solution, there is still no repair solution and nothing to stop them from cracking.
The NRC’s plan is to allow up to a 75% crack in these thin canisters. even though the vendors have no way to locate and measure cracks and there is no seismic rating for cracked canisters. The NRC assumes nothing will go wrong in the first 20 years, and consider “out of scope” anything that may happen after that when they approve the first license. They assume the vendors will eventually solve these problems before these canisters fail. They approved a license renewal for Calvert Cliffs Independent Spent Fuel Storage Facility (ISFSI) with the assumption the technology to inspect loaded canisters will be available within 5 years after license approval. See August 21, 2015 comments submitted to the NRC on their proposed aging management plan in (NUREG-1927 Rev. 1). The NRC has hidden comments from public view (Docket ID NRC-2015-0106).
The unproven experimental Holtec UMAX underground storage system Edison plans to buy has never been used or tested anywhere in the world and has not yet been approved for high seismic areas. Missouri Callaway nuclear power plant installed the underground system recently. Tentative first spent fuel loading is July 2015. The thin welded canisters are to be inserted in steel lined concrete holes. The unsealed thick top lids have air vents, so the thin canisters and spent nuclear fuel waste do not overheat.
The NRC approved a Holtec license amendment to use the Holtec HI-STORM UMAX system in high seismic risk areas effective September 8, 2015. However, it is not approved for any specific site, including San Onofre; that requires additional approvals. And they are only certified safe for 20 years. Any issues that may occur after 20 years are not considered by the NRC, even though they know they must last for decades and they do not have aging issues resolved. See more details below and on Nuclear Waste page.
- Holtec International HI-STORM UMAX Canister Storage System, Certificate of Compliance No. 1040, Amendment No. 1 Direct Final Rule, Federal Register Vol. 80, No. 173, pp 53691 – 53694, effective September 8, 2015
- Letter To Coastal Commission regarding Holtec UMAX NRC approval, September 18, 2015, outlines the limitations of the approval:
- Excludes site approval, such as San Onofre. This requires additional approvals.
- Certified safe for only the initial 20 years. Ignores aging management issues.
- Excludes any plan for storing failed (cracking) canisters. No vendor casks have been approved for storing or transporting failed canisters and no vendor has submitted an application for this purpose.
- Approved for 0.5” thick canisters – not the 0.625” thickness San Onofre proposes. The NRC has not received a License Amendment Request from Holtec for the 1/8″ thicker canister design. This process can take up to 18 months.
- The underground system design certified is different than the system design proposed for San Onofre. The San Onofre design is only partially underground.
.The Nuclear Regulatory Commission (NRC) licensed the Holtec UMAX system effective April 6, 2015, for low seismic areas, for 20 years, by ignoring known aging problems that may occur after 20 years. The NRC required additional seismic analysis and conditions before approving the License Amendment for high seismic risk areas. The NRC has a history of approving nuclear power plants and storage canisters in high seismic areas, such as Diablo Canyon in San Luis Obispo County. And the NRC only requires evaluation of seismic risk on intact canisters, not canisters that may be cracking. More…
Conditions for cracking were found on a Diablo Canyon canister in service for only two years. No one knows if it is cracking due to the inability to inspect for cracks, but they know it has all the conditions to initiate cracks. The Diablo Canyon nuclear power plant is located near the Pacific Ocean in San Luis Obispo County. Salt in marine environments can corrode these stainless steel canisters and leads to “chloride-induced stress corrosion cracking.” Numerous other environmental factors can corrode thin steel canisters and their concrete overpacks, but the NRC has not fully evaluated these yet. More…
The thin canister vendors, nuclear industry and utilities, and others ignore the Diablo Canyon and Koeberg data when they make unsubstantiated claims these canisters will last. They will claim they are not aware of any cracking problems. That’s because they do not have technology available to inspect for cracks or to measure crack depth. More…
Other countries use casks up to 20″ thick that don’t crack and that are transportable without the need to buy an additional transport cask, which the thin canisters require.

This assumes the Department of Energy will start taking the waste in 2024. However, Edison has provided no data to support this unlikely date. It also assumes the canisters will never crack and will never need to be replaced even though the NRC says the waste may be here indefinitely.

- The NRC staff finds that the schedule for decommissioning activities is adequate to achieve SONGS, Units 2 and 3, license termination within 60 years of permanent cessation of operations (June 2013), as required by 10 CFR 50.82(a)(3). However, the NRC considers out of scope of this review “questions or comments about the performance, design requirements, and the availability of inspection and repair methods of spent fuel storage casks previously certified or under review by the NRC (Note: these issues are addressed during NRC’s licensing of the spent fuel storage casks, or during cask license renewal).”
- San Onofre Nuclear Generating Station, Units 2 and 3 – Review and Approval of the Irradiated Fuel Management Plan (TAC NOS. MF4894 AND MF4895), ML15182A256, August 19, 2015
- The NRC staff finds the SONGS IFMP estimates to be reasonable, based on a cost comparison with similar decommissioning reactors, while acknowledging that there are large uncertainties and potential site-specific variances that may impact these cost estimates in the future.
- The NRC staff has determined that storing fuel in either the spent fuel pool or ISFSI represents an acceptable means for storing irradiated fuel. The licensee’s plan contains both storage methods, with irradiated fuel being taken out of the spent fuel pool and fully transitioned to the ISFSI within 5 years, followed by complete dry storage.
- The anticipated date to transfer fuel to DOE and subsequent decommissioning of the ISFSls are scheduled to be completed in 2051. This supports the requirement to complete decommissioning within the 60-year timeframe, as required by 10 CFR 50.82. [This schedule assumes there will be a place to start sending this fuel by 2024, which Edison’s own witness said was “unknowable” and unlikely]. It also assumes fuel assemblies will not need to be reloaded into DOE approved casks. Current DOE standard contract requires this.

California Coastal Commission (enforces Coastal Act)
- Edison submitted an NRC License Amendment Request on August 20, 2015 to lower safety standards for spent fuel pool cooling so they can install a air-chiller system that doesn’t meet nuclear grade standards, including earthquake standards. At the August 13, 2015 Coastal Commission meeting, the Coastal Commission approved a permit for this cooling system. However, it was based on assurances from Commission staff and Edison that it met high seismic standards. Therefore, this decision should be reversed.

San Onofre’s nuclear reactors are shut down. However, thousands of metric tons of radioactive nuclear waste, such as Cesium-137 will remain in California for decades. San Onofre’s spent fuel contains 89 times the amount of Cesium-137 released from Chernobyl. The waste is not safely stored, putting us at risk for a major nuclear disaster. Please read these facts and share the information. The facts are from the Nuclear Regulatory Commission (NRC) and other government and scientific sources. More…
The (1/2 – 5/8 inch) thin stainless steel canisters storing radioactive nuclear waste at U.S. nuclear power plants may fail within 30 years. There is no current replacement plan. Waste may need to be stored at nuclear plants sites for over 100 years. Once canisters are loaded with waste, they are no longer inspected for aging or monitored for helium leaks. These are just some of the problems with U.S. dry storage systems. More…
This is SanOnofreSafety.org founder Donna Gilmore’s presentation to the NRC on dry cask nuclear waste storage issues, delivered by invitation as part of an NRC Regulatory Conference held Nov. 19-20, 2014 in Rockville, Maryland. Why are the NRC and Southern California Edison favoring inferior, short-lived, thin-walled, unsafe stainless steel canisters to store San Onofre’s tons of nuclear waste in a corrosive seaside environment instead of the long-lasting, thick-walled, top-of-the-line technology available?
Gilmore presents a strong case for regulators and utilities to take the lead in setting the highest possible standards for America’s growing inventory of radioactive waste that will remain deadly for hundreds of thousands of years longer than human civilization has yet existed. With no safe long-term storage sites having been found despite over half a century of attempts to find them, Gilmore urges officials not to ‘play bureaucratic roulette’ with the future of California and the rest of the nation.

Nuclear industry vendor, Areva, admits to having no answer to replacing failed nuclear waste storage canisters once spent fuel pools are destroyed. NRC admits to no current method to inspect for cracks in nuclear waste canisters.
More questions than answers regarding critical dry storage issues at the NRC November regulatory conference on nuclear waste.
Dr. Wolfgang Steinwarz, Executive Vice President of the German dry cask manufacturer Siempelkamp – whose highly robust nuclear waste storage containers are in use around the world (with only limited use in the U.S.) – explains how his company’s technology is setting a high international bar for safe, long-term radioactive waste containment. Dr. Steinwarz is an internationally renown expert in ductile cast iron technology. This is his presentation from the November 19-20, 2014 NRC Annual Regulatory Conference, held in Rockville, Maryland.
HIGH BURNUP FUEL: San Onofre and other U.S. reactors switched to more dangerous high burnup nuclear fuel over a decade ago. High burnup fuel is low enriched uranium that has burned longer in the reactor than lower burnup fuel.
It’s hotter and over twice as radioactive as lower burnup fuel and unpredictable and unstable in storage and transport. The protective Zirconium fuel cladding is more likely to become brittle and shatter.
The majority of spent nuclear fuel at San Onofre falls into the danger zone as shown by the yellow in this Waste at SONGS chart.
Burnup levels as low as 30 GWd/MTU show indications of damaging the protective Zirconium cladding.
Other U.S. nuclear plants have spent fuel that falls within the danger zone, including Diablo Canyon in San Luis Obispo County. More…
There is no approved method to safely store high burnup fuel in dry casks for more than 20 years. And there is no approved method to safely transport high burnup fuel waste. This fuel is so hot, it must cool in the spent fuel pools years longer than lower burnup fuel. Edison plans to store high burnup fuel in a new model dry cask that would make it even more dangerous. More….
The San Onofre Nuclear Power Plant has the worst safety complaint record of all U.S. nuclear reactors according to Nuclear Regulatory Commission (NRC) safety allegation data. See charts for details. Employees are retaliated against for reporting safety problems. See Safety Allegations Section for details on this and other safety complaints by employees and others. More…
Southern California Edison wanted to restart the Unit 2 nuclear reactor without fixing the defective steam generators. Both reactors have been shut since 1/31/2012, when Unit 3 leaked radiation into the environment. All four poorly designed replacement steam generators show decades of tube wear after less than two years of installation — the worst in the nation.
The NRC concluded Southern California Edison was at fault. “…a significant design deficiency in replacement steam generators, resulting in rapid tube wear of a type never before seen in recirculating steam generators.” In the NRC’s 12/23/2013 NRC Notice of Violation, they stated: “…design control measures were not established to provide for verifying or checking the adequacy of certain designs.”
Edison now admits the steam generators are lemons. However, they were willing to restart Unit 2 without repairing them. Edison and Mitsubishi Heavy Industries (MHI) redesigned the steam generator tube anti-vibration system in order to increase profits. They removed the central stay cylinder in order to add about 400 extra tubes to each generator. Read Arnie Gundersen’s Fairewind Associates Report San Onofre’s steam generators: significantly worse than all others nationwide and 10/2/2014 NRC Office of Inspector General report where former NRC directors say the steam generators should never have been licensed. More…
California has excess power without California’s unreliable nuclear power plants, even during peak summer months, according to California government documents. There should be no power problems with San Onofre shut down, even during the summer. And the California ISO’s electricity grid Transmission Plan says there will be no grid stability concerns with San Onofre shut down. More…
The San Onofre and Diablo Canyon nuclear plants kill millions of fish and other marine life every year, due to their once-through cooling (OTC) systems. The Federal Clean Water Act §316(b) regulations declared OTC illegal. However, California is allowing both plants to continue OTC for years. More….
.Senator Barbara Boxer to NRC Commissioners
Four NRC Commissioners undermine safety. Rep. Darrell Issa appears to support them.
San Onofre, designed for a 7.0 earthquake, but has 8.0+ earthquake probability — 10x larger, 32x stronger, & overdue. Ratepayers funding $64 million in new seismic studies, even though the USGS states no scientist can predict the size of any earthquake. Some recent large quakes:
- Chile 4/1/2014 8.2 – 63x stronger
Nuclear meltdown at San Onofre would poison the nation’s food supply, create permanent “dead zones” and create financial ruin around the nation. If you live within 50 miles of San Onofre, you are at even higher risk of losing everything you care about here. Five counties are within the 50 mile zone: Los Angeles, Orange, Riverside, San Bernardino and San Diego.
There is no safe level of radiation, according to the National Academy of Sciences. Children, unborn babies and women are more susceptible to the effects of radiation. Ingesting radiation is extremely dangerous. More…
Photo of children tested for radiation near Fukushima Daiichi nuclear plant in Japan (Kim Kyung-Hoon/Reuters)
Radioactive Cesium from Japan was found in tuna in San Diego. Kelp along the Orange County coast contained Fukushima radiation. Radiation monitoring is inadequate. Government resources and priorities for radiation monitoring are too low to protect us. More…
The Fukushima Daiichi nuclear disaster continues and radiation from Fukushima has traveled to the U.S., yet limited radiation data is available to the public. See NRC Fukushima Lesson’s Learned for status of what the NRC and U.S. reactors are doing [or not doing] to avoid similar problems.
What if the Fukushima nuclear fallout crisis had happened in California? These radioactive plumes from severe nuclear accidents were calculated by NRDC based on the actual weather patterns of March 11-12, 2011. The result on any given day will vary according to the type of reactor accident and on the prevailing weather patterns at the time. These plumes artificially extend only to 50 feet. Winds can carry them further. See NRDC interactive U.S. map.
Without public awareness and involvement this nuclear energy experiment will continue. Our government will only stop approving high burnup nuclear fuel if our elected officials know they will not be reelected if they support this nuclear energy experiment. We need better nuclear waste storage containers that are designed for safety over cost. We don’t need to live with these serious risks for energy we don’t need. See Energy Options.

About San Onofre Safety (SOS)
This website is a self-funded public resource for creditable information about San Onofre Nuclear Power Plant safety issues, cost issues and related information. Much of the information is relevant to other nuclear power plants and their nuclear waste. The information was extensively research and fact checked by local citizens and organizations concerned about the risks from San Onofre and other nuclear power plants. By improving public awareness, our goal is to reduce the likelihood of a nuclear disaster in California and elsewhere. The San Onofre nuclear reactors and highly toxic radioactive waste storage facilities are located just south of San Clemente, California. Diablo Canyon nuclear power plant is located in San Luis Obispo county. California’s Humboldt and Rancho Seco nuclear reactors are shut down, but their highly toxic radioactive waste is stored on-site — indefinitely.
Southern California Edison decided to decommission the San Onofre nuclear reactors on June 7th, 2013, after the NRC’s Atomic Safety and Licensing Board said restarting the Unit 2 reactor would be a nuclear experiment.
