Tuesday’s event comes as regulators announce an “expansive investigation” into whether the plant’s operator rejected safety measures that could have prevented a radiation leak last year.
The plant was shut down in January after discovery of a small radiation leak that has been linked to rapid tube wear.
The top nuclear regulator suggests that problems at the San Onofre power plant indicate the need for rule changes.
Senator formally requests documents on the approval of design changes following reports of a missing record and detailed allegations of an improper approval process.
Plant operator’s presentation to regulators didn’t include major design changes that an expert says should have been reviewed by the government.
Presentation by the plant’s operator discussed design changes to be made without the most thorough federal review.
The proposal draws a swift rebuke from environmental advocates.
Neither the government nor the nuclear plant’s operator will say whether three key changes, which a nuclear expert claims caused a small radiation leak, were reviewed by regulators.
Despite improvements in its safety culture, the nuclear plant last year generated safety allegations at more than six times the national average.
The design changes caused the extremely rapid wear on generating tubes that forced the shutdown of the nuclear plant, according to an expert.
