The following technical tasks will be completed to support the Nuclear Power Plant Assessment. These tasks were specified in AB 1632, which was codified in PRC sections 25303(a)(8)(A-D) and 23303(c). The task numbers presented here (beginning with Task 2), match the Energy Commission’s Request For Proposals (RFP) #150-07-101, “AB 1632 Nuclear Power Plant Assessment.”2 The task descriptions below identify the topic areas to be addressed and the scope of the assessment to be conducted for each task. Additionally, each task description includes a representative list of studies and documents from government agencies, industry, academia, and other experts that the contractor expects will be reviewed in the course of completing the AB 1632 assessment. These lists illustrate the types of documents that the contractor will review and are not intended to be comprehensive. Task 2: Seismic Vulnerability Assessment In this task, the contractor will review studies that assess the vulnerability of Diablo Canyon and SONGS to a major disruption due to seismic or tsunami hazards and identify the cumulative damage that is anticipated at each plant as a result of earthquakes and tsunamis of various magnitudes. A team of experts from the California Department of Conservation, California Seismic Safety Commission, and California Coastal Commission will act in an advisory role to the contractor for this assessment.
