Other Steam Generator Reports
The new steam generators are designed to last longer, said Mike Wharton, manager of the steam-generator replacement project. “They are designed for 40 years,” he said. “We expect we’ll actually be able to get 60 years out of them … better materials, better design. You learn over the course of years what works well and what doesn’t, and you try to build it into the next generation.”
Victor Dricks, a spokesman for the U.S. Nuclear Regulatory Commission, said the NRC has had a special team of inspectors on site monitoring the entire steam-generator replacement.
“We have reviewed their plan, observed their cutting into the containment and removal of the old steam generators, their replacement and the pouring of concrete last weekend to repair the cut containment walls,” Dricks reported. “A special team of NRC inspectors, including specialists with industry-wide experience in steam-generator replacement, have been following this project carefully. Their findings will be contained in a special report to be written early next year that will be publicly available.”
