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
Tim Abney 3
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 4
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

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
