SUMMARY

OF DECEMBER 1, 2009, PRE-APPLICATION MEETING WITH TENNESSEE VALLEY AUTHORITY REGARDING PROPOSED ALLOWED OUTAGE TIME ONE-TIME EXTENSION FOR THE CHILLER UPGRADE PROJECT AT WATTS BAR NUCLEAR PLANT, UNIT 1 On December 1, 2009, a Category 1 public meeting was held between the U.S. Nuclear Regulatory Commission (NRC) and representatives of Tennessee Valley Authority (TVA) at NRC Headquarters, One White Flint North, 11555 Rockville Pike, Rockville, Maryland. The purpose of the meeting was to discuss the TVAs pre-application proposed allowed outage time (AOT) one-time extension amendment request for a chiller upgrade project at Watts Bar Nuclear Plant (WBN), Unit 1.

A list of attendees is provided in Enclosure 1 and TVA=s handouts provided at the meeting are included in Enclosure 2.

TVA gave a brief presentation including introductions, purpose of the pre-application meeting, the reason for the need for a chiller upgrade project, the plan for accomplishing the chiller upgrade project, and the proposed schedule for the chiller upgrade project.

TVA needs to replace the Train-A and Train-B Main Control Room (MCR) chillers and the Shutdown Board Room (SDBR) chillers due to Executive Order 13148 that requires all Federal Agencies to phase out procurement of Class 1 ozone-depleting refrigerants by December 31, 2010 (R-11 used in SDBR Chillers) and Clean Air Act requires production of R-22 refrigerant to be phased out by 2020 (MCR chillers).

TVA plans to perform the Chiller Upgrade Project in three phases. Phase 1 will be the replacement of Train-B SDBR chiller beginning on October 1, 2010, during WBN Unit 1 operation, and the Phase 1 work is estimated to take approximately 55 days. Phase 2 will be the replacement of Train-B MCR chiller beginning approximately December 1, 2010, during WBN Unit 1 operation, and the Phase 2 work is estimated to take approximately 62 days. Phase 3 will be the replacement of Train-A SDBR and MCR chillers beginning on October 1, 2011, during WBN Unit 1 operation, and the Phase 3 work is estimated to take approximately 68 days. TVA plans to complete all phases of the chiller upgrade project by December 20, 2011.

TVA proposes to request a one-time AOT extension from 30 days to 60 days for Technical Specification 3.7.11, Control Room Emergency Air Temperature Control System, while WBN Unit 1 is operating while provided specified compensatory measures are taken. TVA plans to install and maintain a temporary non-safety-related chilled water system.

TVA plans to submit the proposed amendment request by December 18, 2009, and TVA plans to request NRC approval by December 1, 2010.
