Tennessee Valley Authority ATTN: Mr. J. A. Scalice Chief Nuclear Officer and Executive Vice President 6A Lookout Place 1101 Market Street Chattanooga, TN 37402-2801

SUBJECT:

NOTIFICATION OF BROWNS FERRY NUCLEAR POWER PLANT - SAFETY SYSTEM DESIGN AND PERFORMANCE CAPABILITY INSPECTION NRC INSPECTION REPORT NOS. 50-259/2002-05, 50-260/2002-05, AND 50-296/2002-05

Dear Mr. Scalice:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)

Region II staff will conduct a Safety System Design and Performance Capability inspection at your Browns Ferry facility during the periods December 9-13, 2002 and January 13-17, 2003. A team of five NRC inspectors will perform this inspection. The inspection team will be led by Mr. Caswell Smith, a senior reactor inspector from the NRC Region II office. The inspection will be conducted in accordance with baseline inspection program Attachment 71111.21, Safety System Design and Performance Capability.

The inspection scope will include those components and activities which accomplish the containment heat removal function at your plant. Your Individual Plant Examination shows this function as significant in the successful mitigation of accidents at your Browns Ferry facility.

The inspectors will review design, testing, preventive and predictive maintenance, and material condition of the residual heat removal system and its support systems, to determine if the reviewed items can impact the success of the containment heat removal function. Fire and internal flood contributions that contribute to a loss of the containment heat removal function may be examined. In addition, components and activities which would mitigate the failure of the containment heat removal function (hardened wet well vent, residual heat removal system cross-tie, and others), their support systems, and their related procedures will be examined.

During a telephone conversation on September 30, Mr. Jim Moorman of my staff, and Mr. Jim Davenport of your staff, confirmed arrangements for an information gathering site visit and the two-week onsite inspection. The schedule is as follows:

Information gathering visit: November 4-8, 2002 Onsite inspection: December 9-13, 2002 and January 13-17, 2003

TVA 2

The purpose of the information gathering visit is to obtain information and documentation outlined in the enclosure needed to support the inspection. Mr. R. Bernhard, a Region II Senior Reactor Analyst, will accompany Mr. Moorman during the information gathering visit to review PRA data and identify risk significant components which will be examined during the inspection.

Please contact Mr. Moorman prior to preparing copies of the materials listed in the enclosure.

The inspectors will try to minimize your administrative burden by specifically identifying only those documents required for inspection preparation.

During the information gathering visit, Mr. Moorman will also discuss the following inspection support administrative details: office space; specific documents requested to be made available to the team in their office space at the site; arrangements for plant site access; and the availability of knowledgeable plant engineering and licensing personnel to serve as points of contact during the inspection.

Thank you for your cooperation in this matter. If you have any questions regarding the information requested or the inspection, please contact me at (404) 562-4605, or Mr. Moorman at (404) 562-4647.

Sincerely,
