(AP) – Federal regulators have determined that design flaws appear to be the cause of excessive wear in tubing that carries radioactive water through California’s troubled San Onofre nuclear power plant.
Nuclear Regulatory Commission Regional Administrator Elmo Collins told The Associated Press in an interview that missteps in fabrication or installation are considered as possible sources of the rapid tube decay but “it looks primarily we are pointed toward the design” of the plant’s steam generators.
The NRC is scheduled to discuss its findings Monday evening at a meeting near the plant.
Edison did not immediately comment on the NRC findings.
The company said in a statement the Unit 2 reactor likely would remain offline at least through August, pending NRC approval for a restart
