This is a non-emergency notification. In p … This is a non-emergency notification. In preparation for converting from 10 CFR 50. Appendix R, to NFPA (National Fire Protection Association) 805, a review of the Brunswick Steam Electric Plant (BSEP) Safe Shutdown Analysis identified conditions that may not ensure required equipment remains available under certain postulated fire scenarios. The analysis determined that the effects of a postulated fire in specific fire areas could prevent critical systems or components from performing their intended functions, potentially resulting in the inability to achieve and maintain safe shutdown. Alternate safe shutdown procedures currently credited with bringing about operator actions to mitigate a postulated fire have been found not to contain needed actions.</br>Affected fire areas are RB1-N, RB1-S, RB2-N, RB2-S, DG-07, and DG-08E. A fire in one of these areas could potentially adversely affect Emergency Diesel Generators (EDGs) 2, 3, and 4 along with EDG Building ventilation system components that could fail vital auxiliaries (HVAC) to the affected switchgear rooms.</br>This is reportable as an unanalyzed condition that significantly degrades plant safety in accordance with 10 CFR 50.72(b)(3)(ii)(B). Most required fire watches were already in place as a result of a previous similar event reported in Brunswick ENS Report 47341 and Brunswick LER 1-2011-002. Two additional actions have been taken to establish fire watches in areas containing electrical busses E6 and E7.</br>This condition has been entered into the Corrective Action Program (i.e., CR 619341).</br>The licensee has notified the NRC Resident Inspector.e has notified the NRC Resident Inspector. +
