Enclosure REQUEST FOR ADDITIONAL INFORMATION (RAI) RELATED TO THE LAY-UP EFFECTS OF BROWNS FERRY UNIT 1 STRUCTURES AND COMPONENT SUPPORTS BROWNS FERRY NUCLEAR PLANT LICENSE RENEWAL APPLICATION CIVIL AND ENGINEERING MECHANICS SECTION RAI 3.5-1 Browns Ferry Nuclear Plant (BFN) document titled, "Evaluation of the BFN Unit 1 Lay-Up and Preservation Program," including Tables 1 through 4, does not provide information related to BFNs evaluation of the Unit 1 spent fuel storage system lay-up effects. Please describe the method adopted in assessing the Unit 1 spent fuel storage system related lay-up effects. Also provide a discussion of the applicable spent fuel pool environments (any delta change in pool water chemistry, ambient humidity and temperature, etc.), results of past periodic inspections of the spent fuel pool structural components and pool liners, any observed pool leakages or degraded conditions, and corrective actions taken to support BFNs conclusion that no lay-up effect is applicable to Unit 1 spent fuel storage system.

RAI 3.5-2 Please describe the approach used in evaluating the Unit 1 structures and component supports related lay-up effects. Provide a discussion of the environments applicable to Unit 1 structures and component supports (e.g., any exposure to aggressive chemicals or ponding of water, significant change in ambient humidity and temperature, etc.), results of past periodic inspections of the structures and component supports, any observed degraded conditions, and corrective actions taken to support BFNs conclusion that no lay-up effect is applicable to Unit 1 structures and component supports that require an Aging Management Review (AMR).

RAI 3.5-3 When the plant is operating, the containment drywell, torus, and connecting vent assemblies are subjected to relatively inert environment, and all the requirements related to their inspections, and leak-rate testing are applicable. These requirements ensure the leak tight, and structural integrity of these components. Also, the industry operating experience problems, as reflected in NRCs Generic Letters, Information Notices, and other industry published event reports are considered as applicable. These activities may or may not have been considered for Unit 1 during its long lay-up. In this context, the applicant is requested to provide information that would describe the benchmark condition of the containment pressure boundary related components prior to restart of the Unit, and actions that will be taken prior to the extended period of operation. The relevant regulatory requirements would be:10 CFR 50.55a, and Appendix J of 10 CFR 50. The relevant Generic Letters would be: GL 87-05, GL 89-16, and GL 98-05. The relevant Information Notices would be: IN 86-99, IN 88-82, IN 89-06, IN 89-79, and IN 92-20.
