Director, Division of Spent Fuel Management Office of Nuclear Material Safety and Safeguards U.S. Nuclear Regulatory Commission Washington, DC 20555-001 Docket No. 50-275, OL-DPR-80 Docket No. 50-323, OL-DPR-82 Diablo Canyon Units 1 and 2 Docket No. 72-26, Materials License No. SNM-2511 Diablo Canyon Independent Spent Fuel Storage Installation Emergency Plan Update

Dear Commissioners and Staff:

In accordance with the requirements of 10 CFR 50.54, 10 CFR 72.32, and 10 CFR 72.44(f), Pacific Gas and Electric Company (PG&E) is providing a summary of the analysis of changes to the Emergency Plan (E-Plan) in the associated enclosures listed below:

• Enclosure 1 - Diablo Canyon Power Plant Emergency Plan Table of Contents

• Enclosure 2 - Summary of the Analysis of Changes in Emergency Plan Appendix F, Revision 4.07, "ERO On-Shift Staffing Analysis Report" PG&E evaluated the changes for a reduction in effectiveness, as described in 10 CFR 50.54(q), and concluded that the changes do not reduce the effectiveness of the E-Plan. The E-Plan continues to meet the requirements in Appendix E of 10 CFR 50 and the standards of 10 CFR 50.47(b). Therefore, PG&E concluded that prior NRC approval of the associated changes was not required.

This update does not contain any privacy or proprietary information in accordance with NRC Generic Letter 81-27, "Privacy and Proprietary Material in Emergency Plans."

CP M-10 Removed reference to Casualty Procedure CP M-10, "Fire Protection of Table 3-2: Event Procedures Safe Shutdown Equipment," as it was rescinded as part of the National Fire CP M-10 Protection Association (NFPA) 805 implementation at DCPP under License 6.14 Amendments 225 and 227.

CP M-10, Fire Protection of Safe CP M-10 was used in the station Shutdown Equipment blackout (SBO) scenario in Appendix F.

The applicable action in CP M-10 for the SBO event was to control heat buildup in vital areas. Guidance for this task was added to Emergency Operating Procedure EOP ECA-0.0, "Loss of Vital AC Power," in Attachment 1. ECA-0.0 is already identified in Appendix Funder the SBO event as an applicable procedure.

50.54(q) 2017-12 evaluated the impacts on the E-Plan of transitioning to NFPA 805 including a revalidation of the shift staffing analysis (Revision 4.05 of Appendix F). At the time 50.54(q) 2017-12 was performed CP M-10 had not yet been rescinded, which is why Revision Page 4 of 5

,Change Original Content (Revision 4.06)

• Revised Content (Revision 4.07) Description of Change 4.05 of Appendix F did not include the removal of CP M-10.

The updated staffing analysis that was done as part of the Revision 4.05 change to Appendix F included the use of the updated EOP ECA-0.0 and concluded that no new task overlaps were created for applicable scenarios evaluated under Appendix F.

This change does not affect how the current E-Plan meets any planning standard functions, elements, or site-specific commitments. No additional evaluation required.
