Attachment 1 to GNRO-2016/00051 Description and Assessment of Technical Specifications Changes

GNRO-2016/00051 Description and Assessment

1.0 DESCRIPTION

The proposed amendment would modify technical specifications (TS) requirements for unavailable barriers by adding LCO 3.0.9.

The changes are consistent with Nuclear Regulatory Commission (NRC) approved Industry/Technical Specification Task Force (TSTF) STS change TSTF-427 Revision 2.

The availability of this TS improvement was published in the Federal Register on October 3, 2006, 71 Fed. Reg. 58444 as part of the consolidated line item improvement process (CLIIP).

2.0 ASSESSMENT 2.1 Applicability, of Published Safety Evaluation Entergy Operations, Inc. has reviewed the safety evaluation dated October 3,2006 as part of the CLIIP. This review included a review of the NRC staff's evaluation, as well as the supporting information provided to support TSTF-427. Entergy Operations, Inc. has concluded that the justifications presented in the TSTF proposal and the safety evaluation prepared by the NRC staff are applicable to Grand Gulf Nuclear Station Unit 1 and justify this amendment for the incorporation of the changes to the Grand Gulf Nuclear Station TS.

2.2 Optional Changes and Variations Entergy Operations, Inc. is not proposing any variations or deviations from the TS changes described in the TSTF-427 Revision 2 or the NRC staff's model safety evaluation dated October 3,2006 (71 FR 58444).

On November 27, 2012, the NRC published a Federal Register Notice stating that Regulatory Guide (RG) 1.182 has been withdrawn and the subject matter has been '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." (77 FR 70846). RG 1.160 endorses Revision 2 of NUMARC 93-01, dated April 2011. TSTF-427 and the proposed Bases, the model application and commitments, the model Safety Evaluation, and the implementation guidance reference RG 1.182, "Assessing and Managing Risk Before. Maintenance Activities at Nuclear Power Plants," which endorses the February 200b version of NUMARC 93-01, "Monitoring the Effectiveness of Maintenance at Nuclear Power Plants." References and commitments to RG 1.182 in these documents are assumed to refer to RG 1.160 and Revision 2 of NUMARC 93-01 instead of RG 1.182. References to RG 1.182 in the Technical Specification Bases and model application have been revised to refer to RG 1.160.

3.0 REGULATORY ANALYSIS

3.1 No Significant Hazards Consideration Determination Entergy Operations, Inc. has reviewed the proposed no significant hazards consideration determination (NSHCD) published in the Federal Register as part of the CLIIP. Entergy Operations, Inc. has concluded that the proposed NSHCD presented in the Federal Register notice is applicable to Grand Gulf and is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91 (a).

3.2 Verification and Commitments As discussed in the notice of availability published in the Federal Register on June 2, 2006 for this TS improvement, plant-specific verifications were performed as follows:

1. Entergy Operations, Inc. commits to the guidance of NUMARC 93-01 Section 11, Revision 2A, which provides guidance and details on the assessment and management of risk during maintenance.

2. Entergy Operations, Inc. will revise procedures to ensure that the risk assessment and management process described in NEI 04-08 is used whenever a barrier is considered unavailable and the requirements of LCO 3.0.9 are to be applied, in accordance with an overall configuration risk management program (CRMP) to ensure that potentially risk-significant configurations resulting from maintenance and other operational activities are identified and avoided.

3.3. Precedent The NRC has approved TSTF-427 editorial variations similar to those described in "Section 2.2 Optional Changes and Variations" for a number of plants.

1. Letter from A Muiiiz (U.S. Nuclear Regulatory Commission) to J.M. Davis (Detroit Edison Company), Fermi 2 - Issuance of Amendment RE: Consolidated Line Item Improvement Process (CLIIP) Application for Technical Specification Change (TSTF-427) to Add Limiting Condition for Operation (LCO) 3.0.9 Regarding the Unavailability of Barriers (TAC No. MD4434), dated August 1,2007 (ADAMS Accession No. ML071490013).

2. Letter from P.S. Tam (U.S. Nuclear Regulatory Commission) to T.J. O'Connor (Northern States Power Company), Monticello Nuclear Generating Plant -Issuance of Amendment to Add New Limiting Condition for Operation 3.0.9 Regarding Unavailability of Barriers (TAC No. MD9490), dated October 22, 2008 (ADAMS Accession No. ML082550109).

GNRO-2016/00051 4.0 ENVIRONMENTAL EVALUATION Entergy Operations, Inc. has reviewed the environmental evaluation included in the model safety evaluation dated October 3, 2006 as part of the Cl.ll P. Entergy Operations, Inc. has concluded that the staff's findings presented in that evaluation are applicable to the Grand Gulf Nuclear Station and the evaluation is hereby incorporated by reference for this application.
