Unit 1 Restart - Introduction/Meeting Objectives

• Objectives of this meeting are:

- Provide overview of Unit 1 Restart Project

- Provide schedule of Unit 1 Restart Activities Jon Rupert 2

Regulatory History

• Unit 2 Restart

- All 3 BFN units voluntarily shutdown by TVA in March 1985, because of regulatory and management issues

- TVA committed to obtain NRC approval prior to restart of any BFN unit

- NRC issued a show cause letter for all TVA nuclear plants in September 1985, under 10 CFR 50.54 (f), and requested TVA to specify corrective actions

- TVA submitted the Nuclear Performance Plan, Volume 3, in August 1986, outlining the steps needed to recover the BFN units, specifically directed to Unit 2

- TVA and NRC conducted several meetings and TVA made several submittals to fully define the regulatory actions needed to restart BFN Unit 2

- NRC issued NUREG 1232, Volume 3, Supplement 2 in January 1991, concluding that TVAs actions acceptably addressed BFN deficiencies

- NRC approved Unit 2 restart on May 23, 1991

- Unit 2 restarted on May 24, 1991 Tim Abney 3

Regulatory History

• Unit 3 Restart

- TVA proposed regulatory framework for restart of Units 1 and 3 in July 1991, outlining improvements from the Unit 2 precedent

- NRC approved framework proposed by TVA in April 1992

- Unit 3 restart effort dealt primarily with resolving Special Programs, as the management issues had been resolved for Unit 2 restart

- NRC staff issued SECY-95-264 recommending restart of Unit 3 on November 1, 1995

- NRC approved Unit 3 restart on November 15, 1995

- Unit 3 restarted on November 19, 1995 Tim Abney 4

Regulatory History

• Unit 1

- Based on Energy Vision 2020 recommendations, TVA decided to delay decision on Unit 1 restart

- Unit 1 was removed from the NRCs problem plant list on June 21,1996 based on commitments from an April 16, 1996 TVA letter to:

• Implement same Special Programs on Unit 1 that were done for Unit 3

• Not restart Unit 1 without prior approval of NRC Tim Abney 5
