Enclosure PG&E Letter DCL-15-055 PG&E Response to NRC Request for Additional Information Regarding License Amendment Request 14-03, "License Amendment Request for Adoption of Technical Specification Task Force Traveler TSTF-432, Revision 1, 'Change in Technical Specification End States (WCAP-16294)"'
NRC Request for Additional Information:
In order to justify adoption of the approved TSTF changes, please confirm that Diablo Canyon's current licensing basis adheres to the RG 1. 160 guidance and commitment to the updated version of NUMARC 93-01.
(For details, you may also refer to the NRC staff's recent letter dated, February 26, 2015 (ADAMS Accession No. ML15033A152), in response to the TSTF Group's letter, dated, September 16, 2014 (ADAMS Accession No. ML14259A575), on the subject matter.)
Also, during review of the application, the NRC staff has identified a typo on TS Bases pages 75-86 of 107 and 93-96 of 109 (ADAMS Accession Nos. ML142098075 and ML14209B079), respectively. The bottom left side of these pages refer to 'DIABLO CANYON' as 'DDIABLO CANYON.' Please correct the error (acceptable if corrected during implementation of the amendment).
PG&E Response:
On November 27, 2012, the NRC published a Federal Register Notice stating that Regulatory Guide (RG) 1.182 has been withdrawn and the subject matter has been incorporated into RG 1.160, "Monitoring the Effectiveness of Maintenance at Nuclear Power Plants." RG 1.160 endorses Revision 4A of NUMARC 93-01, dated April2011.
The NRC Model Safety Evaluation for TSTF-432, Revision 1 (contained in Federal Register Volume 77, Number 92, dated May 11, 2012), references RG 1.182, "Assessing and Managing Risk Before Maintenance Activities at Nuclear Power Plants,"
which endorses the February 2000 version of NUMARC 93-01, "Monitoring the Effectiveness of Maintenance at Nuclear Power Plants." References and commitments to RG 1.182 in the NRC Model Safety Evaluation for TSTF-432, Revision 1, are assumed to now refer to RG 1.160 and Revision 4A of NUMARC 93-01 instead of RG 1.182.
Diablo Canyon Power Plant Departmental Administrative Procedure AD7.DC11, "Program Governance for On-Line Maintenance Risk Management," provides expectations for the On-Line Maintenance Risk Management Program structure, content, and implementation. Procedure AD7.DC11 references RG 1.160 as a regulatory standard for the program and references NUMARC 93-01, Revision 4A, as an industry document providing input to the program. Therefore, the Diablo Canyon licensing basis adheres to RG 1.160 and NUMARC 93-01, Revision 4A.

Enclosure PG&E Letter DCL-15-055 The correction of the spelling error in the plant name in the footer of the Technical Specification (TS) Bases pages can be corrected as part of the normal implementation process for the amendment for the license amendment request (LAR) for TSTF-432, Revision 1, since during implementation of the amendments the controlled copy TS Bases pages (which contain the correct plant name spelling in the footer) are marked up with the TS Bases changes identified in the LAR (that do not contain a marked-up change to the plant name in the footer) to create the TS Bases version to be implemented.
