Diablo Canyon: Boxer will seek answers on earthquake risks in Senate hearing

Environment & Public Works committee meets Wednesday – live webcast available

WASHINGTON, D.C. – On Wednesday, December 3, Nuclear Regulatory Commissioners will face tough questions from Sen. Barbara Boxer (D-Calif.) over the NRC’s suppression and rejection of a report that cited dangers at Diablo Canyon nuclear power plant. The report, by Diablo Canyon’s former chief inspector Michael Peck, warned that the plant may not be safe from earthquakes.

Sen. Boxer, chair of the Environment & Public Works Committee, called the hearing after revelations surfaced in August that Peck had filed a formal dissent over inaction by the NRC on startling new seismic information. The dissent detailed how the discovery of new faults, unknown when the plant was designed and built more than 40 years ago, casts doubt on whether the plant can withstand shaking from newly identified earthquake faults surrounding the 1960s-era nuclear reactors on California’s Central Coast.

The NRC kept Peck’s dissent secret for more than a year before denying it in September. Expert testimony will also address the seismic report released by PG&E on the same day as the NRC decision, which revealed that faults surrounding Diablo are far larger and interconnected and therefore capable of stronger shaking than the plant was designed to withstand.
