I. Supplementary Information
On March 4, 2024, the petitioners filed a petition requesting that
the NRC exercise its supervisory authority to order the immediate
closure of Diablo Canyon due to ``the unacceptable risk of a
seismically induced severe accident.'' An order was issued on March 12,
2024, referring the request to the enforcement petition process under
section 2.206 of title 10 of the Code of Federal Regulations (10 CFR),
``Requests for action under this subpart.''
On August 27, 2024, the NRC staff issued an Acknowledgement Letter
that summarized the evaluation activities of the March 4, 2024,
petition, as supplemented on June 7, 2024, and described that the
Petition Review Board (PRB) had accepted four specific concerns for
further review.
Consistent with Section IV.B ``Schedule,'' of the handbook for NRC
Management Directive (MD) 8.11, ``Review Process for 10 CFR 2.206
Petitions,'' and its associated Directive Handbook 8.11, the PRB
intended to issue the proposed director's decision for comment within
120 days after issuing the August 27, 2024, acknowledgment letter. On
October 24, 2024, Pacific Gas & Electric Company (PG&E) provided a
voluntarily submittal to the NRC related to the PRB review of the
petition. On October 31, 2024, the petitioners submitted a supplement
to the petition. The PRB has considered information in the new
supplement and intends to address the following supplemental concerns
in the proposed director's decision:
1. PG&E's 2015 and 2024 seismic source characterizations omitted
modern deformation modeling and failed to use globally-calibrated
strainrate-to-seismicity conversions, that would have prevented their
serious underestimates.
2. Additional justification supporting the use of the Noto
Peninsula earthquake as a model characteristic thrust earthquake for
the Irish Hills.
Consistent with Section III.I.6, ``Supplements to the Petition,''
of the handbook for MD 8.11, the PRB now intends to issue the proposed
director's decision for comment within 120 days of the issuance of the
supplemental acknowledgement letter.
