Reference:

Sequoyah Nuclear Plants, Urits 1 Gonversion to NUREG-1 431, Rev.TVA letter to NRC, "Third Status Update of Planned Maintenance of 6.9 Kilovolt and 480 Volt Shutdown Nuclear Plant, Units 1 and 2:' dated September 30, In accordance with the provisions of 10 CFR 50.90, "Application for amendment of license, construction permit, or early site perrnit," the Tennessee Valley Authority (TVA) is submitting a request for an amendment to Facility Operating License Nos. DPR-77 and DPR-79 for the Sequoyah Nuclear Plant (SQN), Units 1 and 2, respectively.

This amendment request would revise SQN's current Technical Specifications (CTS) to lmproved Technical Specifications (lTS) consistent with the lmproved Standard Technical Specifications (ISTS)described in NUREG-1431, "Standard Technical Specifications - Westinghouse Plants," Revision 4.0. The guidance of Nuclear Energy Institute (NEl) 96-06, "lmproved Technical Specifications Conversion Guidance," dated August 1996, and Nuclear Regulatory Commission (NRC) Administrative Letter 96-04, "Efficient Adoption of lmproved Standard Technical Specifications," oated October 9, 1996, were used in preparing this submittal, The detailed descriptions and justifications to support the proposed changes are provided in Enclosure 2, "SQN ITS Submittal, Volumes 1 through 16." The following Enclosures are also included to assist the NRC in the review of this subrnittal:

Enclosure 1, "Contents of the Sequoyah Nuclear Plant, Units 1 and 2,lmproved Technical Specifications (lTS) Submittal," describes the organization and content of the submittal, including each of the votumes in Enclosure 2.Enciosure 3, "Licensee ldentified Changes That May Require a Formal Technical Branch Review," provides a list and description of the changes included in the ITS submittal that differ from both the CTS and ISTS as described in NUREG -1431, Revision 4.0.I and should bc rvithlrcld fiorn public val ol the proprietary intbrntation.

Enclosure 10, "Relocate Surveillance Frequencies to Licensee Gontrol RITS-TF Initiative 5b C[STF-425),'provides documentation of SQN's Probabilistic Risk Assessment (PRA) technicaladequacy reguired as part of the adoption of TSTF.425.Included In Enclosure 2 are the Bases for the proposed lTS. However, the Bases are not part of the technical specifications but are maintained consistent with the SQN Updated Final Safety Analysis Repoil (UFSAR).Enclosure 4 contains, as noted attachments, the following Westinghouse proprietrary and non-proprietary documents that were attachments to Westinghouse letter LTR-RAM-!-13-032, Rev. 1: 1) Summary Report Revision 1,'Sequoyah Nuclear Plant, Units 1 and 2, lmplementation of Master and Slave Relays Technical Specification Charges Justified in WCAP-14333-P-A, Rev. 1 and WCAP-15376-P-A, Rev. 1,'dated Septem ber 26, 2013, ( Proprietary).

Please note that the CTS marked-up pages do not include NR0-approved Amendments 278 and 289 for Unit 1 and Amendments 269 and279 for Unit 2. These amendments are notto be implemented until start up from the outage where SQN inserts tritium-producing bumable absorber rods in the core. At this time, the production of tritium in the SQN readorc has been delayed indefinitely.

Therefore, the changes associated with these amendments are not included in the ITS submittal.

As described in the referenced letter, several changes are needed at SQN to permit the scheduling of preventive maintenance on the SQN 6.9 Kilovolt (kV) and 480 Volt (V)Shutdown Boards. These changes include: 1) An IAR to allow operation with one essential U. S. Nuclear Regulatory Cornmission Page 4 November 22,2013 raw cooling water (ERCW) pump operable per loop, 2) An LAR to allow operation with one 6.9 kV and associated 480 V shutdown boards inoperable for seven days, and 3) A plant modification to the Auxiliary ControlAir System. The LAR that will allow operation with one ERCW pump per loop has been submitted as listed in Enclosure

6. This submittal proposes the change that will allow operation with a 6.9 kV and associated 480 V shutdown boards inoperable for seven days.TVA requests approval of the proposed license amendment by November 30, 2O14, to support irnplementation prior to the 2015 spring outage. Approval by the proposed date would also accommodate initial license operator training for the class of March 2015. TVA requests an implementation period of 180 days to accommodate completion of implementation activities.

Based on the information provided in Enclosure 2, TVA has determined that there is no significant hazards consideration associated with the proposed change and that the change is exempt from environmental review pursuant to the provisions of 10 CFR 51.22(cXg).

The SQN Plant Operations Review Committee has reviewed this proposed change and determined that operation of SQN in accordance with the proposed change will not endanger the health and safety of the public.Additionally, in accordance with 10 CFR 50.91(bX1), WA is sending a copy of this letter and the enclosures to the Tennessee State Department of Environment and Gonservation.
