By {{letter dated|date=December 15, 2016|text=letter dated December 15, 2016}}, (Agencywide Documents Access and Management System Accession No. ML16355A015), Southern California Edison (SCE) submitted a license amendment request to revise the Permanently Defueled Emergency Plan into an ISFSl-Only Emergency Plan, and revise the Emergency Action Level (EAL) scheme into an ISFSl-Only EAL scheme, for the San Onofre Nuclear Generating Station, Units 1, 2, and 3.

SUBJECT:
SAN ONOFRE NUCLEAR GENERATING STATION, UNITS 1, 2 AND 3 -
REQUEST FOR ADDITIONAL INFORMATION REGARDING THE LICENSE AMENDMENT REQUEST TO CHANGE THE EMERGENCY PLAN AND EMERGENCY ACTION LEVEL SCHEME TO REFLECT AN ISFSI-ONLY CONFIGURATION (CAC NOS. L53160, L53161, AND L53162)
Dear Mr. Palmisano:
By letter dated December 15, 2016, (Agencywide Documents Access and Management System Accession No. ML16355A015), Southern California Edison (SCE) submitted a license amendment request to revise the Permanently Defueled Emergency Plan into an ISFSl-Only Emergency Plan, and revise the Emergency Action Level (EAL) scheme into an ISFSl-Only EAL scheme, for the San Onofre Nuclear Generating Station, Units 1, 2, and 3. The proposed changes would more fully reflect the permanently shutdown status of the facility, as well as the reduced scope of potential radiological accidents once all spent fuel has been moved to dry cask storage within the onsite independent spent fuel storage installation (ISFSI), an activity which is currently scheduled for completion in 2019.
Accordingly, SCE is proposing a new EAL scheme and corresponding emergency plan changes. The proposed changes are being submitted to the U.S. Nuclear Regulatory Commission (NRC) for approval prior to implementation, as required under Paragraph 50.54(q)(4) of Title 10 of the Code of Federal Regulations (10 CFR), regarding reduction in effectiveness of emergency plans,Section IV.B.2 of Appendix E, Emergency Planning and Preparedness for Production and Utilization Facilities, to 10 CFR Part 50, regarding changes to emergency action level schemes, and 10 CFR 72.44(f), regarding the need for Commission-approved emergency plans for ISFSIs.
In order to complete its review, the NRC staff requests additional information as specified in the Enclosure. The requested information was discussed with SCE during a teleconference with NRC staff on April 27, 2017. In order to continue the review of the subject license amendment request, please respond to this request for additional information within 30 days of the date of this letter.
If you have any questions, please contact me at (301) 415-3178 or via e-mail at marlayna.vaaler@nrc.gov.

The proposed changes would more fully reflect the permanently shutdown status of the facility, as well as the reduced scope of potential radiological accidents once all spent fuel has been moved to dry cask storage within the onsite independent spent fuel storage installation (ISFSI),
an activity which is currently scheduled for completion in 2019. The following additional information is necessary to complete the NRC staffs technical review:
BACKGROUND SCE is proposing a new EAL scheme and corresponding emergency plan changes. The proposed changes are being submitted to the U.S. Nuclear Regulatory Commission (NRC) for approval prior to implementation, as required under Paragraph 50.54(q)(4) of Title 10 of the Code of Federal Regulations (10 CFR), regarding reduction in effectiveness of emergency plans,Section IV.B.2 of Appendix E, Emergency Planning and Preparedness for Production and Utilization Facilities, to 10 CFR Part 50, regarding changes to EAL schemes, and 10 CFR 72.44(f), regarding the need for Commission-approved emergency plans for ISFSIs.
REQUESTS FOR ADDITIONAL INFORMATION SONGS-RAI-1 The current EAL PD-HA1 contains the following language, which is consistent with the NRC-endorsed guidance of the Nuclear Energy Institute (NEI) document NEI 99-01, Development of Emergency Action Levels for Non-Passive Reactors (ADAMS Accession No. ML12326A805):
Timely and accurate communications between the SSS [Nuclear Security Shift Supervisor] and the ISS [Control Room] is essential for proper classification of a security-related event.
However, the proposed EAL PD-HA1 for the IOEAL removed this language from the basis.
Please revise EAL PD-HA1 to include this statement in order to be consistent with the NRC-endorsed guidance, or provide a justification for deviating from the endorsed guidance.
SONGS-RAI-2 The proposed EAL PD-HA1 and EAL PD-HU1 have the following language removed from the basis that is in the current EAL PD-HA1 and EAL PD-HU1:
Emergency plans and implementing procedures are public documents; therefore, EALs should not incorporate Security-sensitive information. This includes information that may be advantageous to a potential adversary, such as the particulars concerning a specific threat or threat location. Security-sensitive information should be contained in non-public documents such as the Security Plan.
Since this language remains consistent with NRC-endorsed guidance for an ISFSI-only EALs, please revise EAL PD-HA1 and EAL PD-HU1 to include this language, or provide a justification for its removal since eliminating this language could result in the unintentional disclosure of security-sensitive information.
