Enclosure BROWNS FERRY NUCLEAR, UNITS 1, 2 AND 3 LICENSE RENEWAL APPLICATION REQUEST FOR ADDITIONAL INFORMATION (RAI)

ELECTRICAL AND INSTRUMENTATION AND CONTROL SYSTEMS SECTION 2.5 RAI 2.5-1 Section 2.5.1 of the LRA states that scoping and screening of electrical and I&C components was performed using the spaces approach described in Section 2.1. Were all plant spaces evaluated under this methodology? If any spaces were excluded from evaluation identify those spaces that were excluded and provide the reason why each space was excluded.

RAI 2.5-2 Section 2.5.1 of the LRA states that if a component in a commodity group existed in an area where the area conditions exceeded the commodity groups limiting environmental parameters, a further evaluation could be performed to determine if the component was required for an in-scope systems intended function. Identify all the components that were excluded from the scope of license renewal as a result of these further evaluations and provide the basis used for excluding each component.

RAI 2.5-3 On the three license renewal drawings identified in LRA Section 2.5.1 that depict the recovery path for station blackout (SBO), identify the location of each commodity group component in the recovery path circuit. Do the SBO recovery path circuits include the control circuit wiring that is associated with the power circuits shown on the drawings? If not, why? Are there any underground power circuits used in the SBO recovery paths? If so, were they identified as requiring an AMR? If not, why?

RAI 2.5-4 During a telephone conference held on July 28, 2004, in response to draft request for additional information, D-RAI 3.6-3, the applicant stated that in 1997 a XLPE insulated CCWP capacitor bank cable failed in-service at BFN. Why were these cables not included within the scope of license renewal and identified as a component that requires an AMR?
