In response to a petition filed by environmental groups earlier this year, the Nuclear Regulatory Commission will reinvestigate earthquake fault lines and the potential for seismic activity and ensuing damage at California’s Diablo Canyon nuclear power plant.

The Nuclear Regulatory Commission announced that an agency licensing board will hold oral arguments in a challenge to Pacific Gas and Electric’s application to renew its license for the Diablo Canyon independent spent fuel storage installation in California.

The arguments, which will be open to the public, will be heard by an NRC Atomic Safety and Licensing Board on May 24 beginning at 1 p.m. eastern time.
