LOS ANGELES (AP) — A federal board Friday ordered the operator of a shuttered nuclear power plant in California to turn over dozens of pages of documents that were withheld when the company submitted a plan to restart one of its damaged twin reactors.
The records at issue were prepared by industry experts who have helped Southern California Edison investigate why the San Onofre plant's nearly new steam generators caused excessive wear to hundreds of tubes that carry radioactive water.
The plant was shut in January after a leak in a generator tube released traces of radiation.
In a seven-page order, the Atomic Safety and Licensing Board said it needs the documents for a case related to Edison's restart proposal.
However, the records would not become public. The board — an arm of the Nuclear Regulatory Commission — told the company to prepare an agreement under which the records would be shared only among parties in that case.
In a statement the company said it would "provide documents consistent with the order." On its website, the company says some of the documents prepared by Edison vendors were redacted by those companies to protect "proprietary information." Edison said the omitted information does not affect conclusions in the reports.
The order follows a hearing Monday in which company representatives and board members sparred over of the records' release.
The Nuclear Regulatory Commission has promised a transparent, thorough review of the restart proposal, which focuses on how the utility would operate faulty steam generators installed during a $670 million overhaul in 2009 and 2010. "We don't experiment with safety," NRC Regional Administrator Elmo Collins told reporters in October.
