In the Matter of )) Docket No. 50-391 Tennessee Valley Authority WATTS BAR NUCLEAR PLANT (WBN) - UNIT 2 - GENERIC COMMUNICATIONS STATUS FOR UNIT 2 - REVISION 1 (TAC NO. MD8314)

References:

1. NRC letter dated May 28, 2008, 'Watts Bar Nuclear Plant, Unit 2 - Status of Generic Communications (TAC NO. MD8314)"

2. TVA letter dated March 20, 2008, 'Watts Bar Nuclear Plant (WBN) - Unit 2 -

Generic Communications Status for Unit 2 - Restructured Tables" The purpose of this letter is to respond to an NRC request for additional information (Reference 1) regarding several Generic Communications. TVA provided a comprehensive list of the status of completion of Generic Communications for WBN Unit 2 on March 20, 2008 (Reference 2).

In Reference 1, the NRC did not agree with TVA's determination that certain Generic Communications were not applicable for WBN Unit 2. NRC requested further information to reconcile the differences between TVA's determination and the NRC assessment on thirteen specific Generic Communications. Enclosure 1 provides further information on the Generic Communications in the same form as provided in Reference 2. Enclosure 2.provides the listing of open actions required for licensing identified in this letter.

GENERIC COMMUNICATIONS: REVISION I CHANGES ITEM TITLE REV ADDITIONAL INFORMATION C 79-023 Motor Starters and Contactors Failed to C The Circular did not require a response.

Operate 01 TVA reported a nonconformance under 10 CFR 50.55e on January 17, 1980, that four motor starters of this type had been located in the 480V control and auxiliary vent boards at WBN.

Gould factory representatives supervised the replacement of the carrier assemblies in accordance with the Gould instructions.

The starters with replaced carriers were acceptable.

NRC IR 50-390/80-03 and 50-391/80-02 reviewed and closed the associated nonconformance reports.

C 79-025 Shock Arrestor Strut Assembly C The Circular did not require a response.

Interference 01 TVA reported a nonconformance under 10 CFR 50.55e on March 6, 1980, that a review had determined that nine installed supports had brackets with the potential of hindering full function of the support. Additional supports that were not installed had the same potential problem. TVA initially determined that the supports would be modified in accordance with a vendor approved drawing. TVA subsequently determined that no actual problem existed and no field work was required.

NRC IR 50-390/83-15 and 50-391/83-11 reviewed and closed the associated nonconformance reports.

C 81-013 Torque Switch Electrical Bypass Circuit C The Circular did not require a response.

for Safeguard Service Valve Motors 01 TVA reported a nonconformance under 10 CFR 50.55e on April 4, 1986 (NCR W367-P), that required closing torque switches were found improperly wired. This issue (Torque switch and overload relay bypass capability for active safety related valves) is part of the Electrical Issues Corrective Action Program for WBN Unit 2.

GL 79-024 Multiple Equipment Failures in NA GL 79-24 provided a discussion of an inadvertent reactor scram Safety-Related Systems and safety injection during monthly surveillance tests of the 01 safeguards system at a PWR facility. The GL requested a review to determine if similar errors had or could have occurred at other PWRs. The GL further requested a review of management policies and procedures to assure that multiple equipment failures in safety-related systems will be vigorously pursued and analyzed to identify significant reduction in the ability of safety systems to function as required. A response was requested within 30 days of receipt of the GL with the results of these reviews. TVA does not have a record of receiving or responding to this GL. Thus, WVA concluded that this item was applicable only to PWRs with an operating license at the time the GL was issued.

GL 79-051 Follow-up Actions Resulting from the NA GL 79-51 provided follow-up actions resulting from the Three NRC Staff Reviews Regarding the TMI-2 Mile Island Unit 2 accident. GL 79-51 was provided for planning Accident 01 and guidance purposes. Its principal element was a report titled "TMI-2 Lessons Learned Task Force Status Report and Short-Term Recommendations" (NUREG-0573). This GL and the NUREG were superseded by GL 80-90 and NUREG-0737. See GL 80-90 for further information.

• A ITEM TITLE REV ADDITIONAL INFORMATION GL 79-063 Upgraded Emergency Plans C GL 79-63 advised applicants for licenses of proposed rulemaking that NRC concurrence in State and local emergency plans would 01 be a condition for issuing an operating license. TVA responded to GL 79-63 on January 3, 1980, and confirmed the intent to revise the Emergency Plan to address the NRC requirements.

GL 80-011 B 80-03, "Loss of Charcoal From C GL 80-11 transmitted Bulletin 80-03. TVA responded to B 80-03 Standard Type II, 2 Inch, Tray Absorber on March 21, 1980. See B 80-03 for further information.

01 GL 80-032 Information Request on Category I C GL 80-32 transmitted NRC questions on masonry walls.

Masonry Walls Employed by Plants TVA provided the information requested by letters dated Under CP and OL Review 01 February 12, 1981, for reinforced walls and August 20, 1981, for nonreinforced walls. TVA provided a final response on January 22, 1982. See B 80-11 for further information.

GL 80-092 B 80-21, "Valve Yokes Supplied by C GL 80-92 transmitted Bulletin 80-21. TVA responded to Malcolm Foundry Company, Inc." B 80-21 on May 6, 1981. See B 80-21 for further information.

GL 89-002 Actions to Improve the Detection of C GL 89-02 did not require a response.

Counterfeit and Fraudulently Marketed Products 01 WBN Unit 2 program for procurement and dedication of materials is based in part on and complies with the guidance of GL 89-02. The program is implemented through project procedures.

GL 89-021 Request for Information Concerning O TVA responded to GL 89-21 with the status of USIs for both units Status of Implementation of Unresolved on November 29, 1989. NRC provided an assessment of WBN Safety Issue (USI) Requirements 01 USI status on May 1, 1990. The NRC assessment included a list of incomplete USIs for WBN. USIs were initially reviewed for WBN in the SER Appendix C. USIs were subsequently reviewed in SSER 15 Appendix C (June 1995) and SSER 16 (September 1995).

Unit 2 actions: Provide a status of WBN Unit 2 USIs.

Complete implementation of USIs.
