On Thursday, Edison spokesman Gil Alexander said that other nuclear power plants with retrofitted steam generators had experienced increased wear in the short period after the upgrades occurred.
Scott Burnell, a spokesman for the NRC confirmed Friday that plants similar in design to San Onofre, which also have large steam generators, have experienced additional wear around brackets that hold up the thousands of thin metal tubes inside.
“Our working hypothesis here is that what we’re seeing at San Onofre is the same sort of phenomenon that we’re investigating at other plants,” Burnell said.
The NRC spokesman said he did not have a full list of U.S. plants that have experienced similar wear, but did rattle off three other stations from memory.
The St. Lucie Nuclear Power Plant in Florida
The Arkansas Nuclear One plant in Russellville Ark
The remaining operational reactor at the Three Mile Island plant in Pennsylvania
Now the only question is, how many other reactors did they not want to admit to having corrosion problems at this time?
