EVALUATION

1.

DESCRIPTION Enclosure PG&E Letter DCL-14-058 This letter is a request to amend Operating Licenses DPR-80 and DPR-82 for Units 1 and 2 of the Diablo Canyon Power Plant (DCPP), respectively. The proposed amendment would modify technical specifications (TS) to risk-inform requirements regarding selected Required Action End States. The changes are consistent with Technical Specification Task Force (TSTF) Standard Technical Specification (STS) Change Traveler TSTF-432, Revision 1, "Change in Technical Specifications End States (WCAP-16294)," (Reference 1). The availability of this TS improvement was announced in the Federal Register on May 11, 2012 (77 FR 27814) (Reference 2), as part of the consolidated line item improvement process (CLIIP).

2.

ASSESSMENT 2.1 Applicability of Topical Report, TSTF-432, and Published Safety Evaluation Pacific Gas and Electric Company (PG&E) has reviewed Westinghouse Topical Report (TR) WCAP-16294 (Reference 3), the Nuclear Regulatory Commission (NRC) safety evaluation (SE) for WCAP-16294 (Reference 4), TSTF-432, Revision 1 (Reference 1), and the NRC model SE in Reference 2. PG&E has concluded that the technical bases described in the WestinghouseTR and TSTF-432, as well as the associated SEs prepared by the NRC staff are applicable to DCPP Units 1 and 2 and support incorporation of this amendment request into the DCPP Units 1 and 2 TS.

Table 1, "Summary of DCPP Units 1 and 2 Proposed Changes to End States," is included in this License Amendment Request (LAR) to provide a summary comparison of the proposed DCPP end state changes to those changes approved in the NRC Staff's model SE. Table 1 is based on the table titled, "Proposed Changes to End States," contained in the NRC Staff's model SE (Pages 7 -9).

PG&E previously submitted an LAR for TSTF-505 in PG&E Letter DCL-13-1 06, "License Amendment Request 13-02 Revision to Technical Specifications to Adopt Risk Informed Completion Times TSTF-505 (ML13330A557), Revision 1, 'Provide Risk-Informed Extended Completion Times-RITSTF Initiative 48,"' dated November 25, 2013. The LAR for TSTF-505 includes changes toTS 3.3.2, 3.6.6.A, 3.7.7, 3.7.8, 3.8.1, 3.8.4, 3.8.7, and 3.8.9, including addition of newTS Conditions for inoperability of multiple channels, trains, or systems that results in a complete loss of safety function (e.g., two engineered safety feature actuation system 1

Enclosure PG&E Letter DCL-14-058 instrumentation trains inoperable, one containment spray train and two containment fan cooling unit trains inoperable, two or more Diesel Generators (DGs) and one or more required offsite circuits inoperable).

The TSTF-432 changes toTS 3.3.2, 3.6.6.A, 3.7.7, 3.7.8, 3.8.1, 3.8.4, 3.8.7, and 3.8.9 do not include conditions in which there is a complete loss of safety function. The required revisions to the TS contained in the LAR for TSTF-505 to appropriately implement the TSTF-432 changes (forTS conditions where there is no complete loss of safety function) are described in the Notes column in Table 1.The required TS changes to the TS contained in Attachment 2 to PG&E Letter DCL-13-1 06 are contained in Attachment 4 to the Enclosure of this letter.

2.2 Optional Changes and Variations PG&E is not proposing any variations or deviations from the Westinghouse topical report, the TS changes described in the TSTF-432 Revision 1, or the NRC Staff's model SE published in the Federal Register on May 11, 2012 (77 FR 27814), as part of the CLIIP Notice of Availability.

3.

REGULATORY EVALUATION 3.1 Significant Hazards Consideration PG&E has evaluated whether or not a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:

1. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No.

The proposed change modifies the end state (e.g., mode or other specified condition) which the Required Actions specify must be entered if compliance with the Limiting Conditions for Operation (LCO) is not restored. The requested Technical Specifications (TS) permit an end state of Mode 4 rather than an end state of Mode 5 contained in the current TS. In some cases, other Conditions and Required Actions are revised to implement the proposed change. Required Actions are not an initiator of any accident previously evaluated. Therefore, the proposed change does not affect the probability of any accident previously evaluated. The affected systems continued to be required to be operable by the TS and the Completion Times specified in the TS to restore equipment to operable status or take other remedial Actions remain 2

Enclosure PG&E Letter DCL-14-058 unchanged. WCAP-16294-NP-A, Revision 1, "Risk-Informed Evaluation of Changes to Tech Spec Required Action Endstates for Westinghouse NSSS PWRs," demonstrates that the proposed change does not significantly increase the consequences of any accident previously evaluated.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

2. Does the proposed change create the possibility of a new or different accident from any accident previously evaluated?

Response: No.

The proposed change modifies the end state (e.g., mode or other specified condition) which the Required Actions specify must be entered if compliance with the LCO is not restored. In some cases, other Conditions and Required Actions are revised to implement the proposed change.

The change does not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed) or a change in the methods governing normal plant operation. In addition, the change does not impose any new requirements. The change does not alter assumptions made in the safety analysis.

Therefore, the proposed change does not create the possibility of a new or different accident from any accident previously evaluated.

3. Does the proposed change involve a significant reduction in a margin of safety?

Response: No.

The proposed change modifies the end state (e.g., mode or other specified condition) which the Required Actions specify must be entered if compliance with the LCO is not restored. In some cases, other Conditions and Required Actions are revised to implement the proposed change.

Remaining within the Applicability of the LCO is acceptable because WCAP-16294-NP-A demonstrates that the plant risk in MODE 4 is similar to, or lower than, MODE 5. As a result, no margin of safety is significantly affected.

Therefore, the proposed change does not involve a significant reduction in a margin of safety.

Based on the above evaluation, PG&E concludes that the proposed change does not involve a significant hazards consideration under the 3

Enclosure PG&E Letter DCL-14-058 standards set forth in 10 CFR 50.92(c), and accordingly, a finding of "no significant hazards consideration" is justified.

3.2 Applicable Regulatory Requirements/Criteria A description of the proposed TS change and its relationship to applicable regulatory requirements were published in the Federal Register Notice of Availability on May 11, 2012 (77 FR 27814). PG&E has reviewed the NRC Staff's model SE referenced in the CLIIP Notice of Availability and concluded that the regulatory evaluation section is applicable to DCPP Units 1 and 2.

4.

ENVIRONMENTAL CONSIDERATION PG&E has evaluated the proposed amendment and has determined that the proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.
