While performing a post-fire safe shutdown … While performing a post-fire safe shutdown (PFSSD) review per Enforcement Guidance Memorandum (EGM) 09-002, 'Enforcement Discretion for Fire Induced Circuit Faults', and Regulatory Guide (RG) 1.189, Revision 2, five issues were identified that could be potentially reportable. EGM 09-002 provides enforcement discretion for non-compliances related to fire-induced multiple spurious operations (MSOs). The enforcement discretion period allows 6 months from the date of issuance of RG 1.189, Rev. 2 to perform the following:</br> - Identify noncompliances related to multiple fire induced circuit failures</br> - Implement compensatory measures for the noncompliances, and</br> - Place the noncompliances in the licensees' corrective action program</br>The five fire-induced issues that were identified are:</br> - Three issues which could potentially prevent operation of the Residual Heat Removal Pump(s),</br> - An issue where all four Reactor Coolant Pumps may not stop from the Control Room, and </br> - An issue where a Centrifugal Charging Pump could spuriously start and fill the pressurizer solid.</br>RG 1.189 was issued on November 2, 2009. Therefore, the 6-month identification period ends on May 2, 2010. For issues identified during the 6-month identification period, enforcement discretion continues for an additional 30 months to resolve identified issues.</br>The 10 CFR 50, Appendix R Fire is not a Design Basis Accident. While Appendix R fires are postulated to cause a Technical Specification (TS) inoperability of a (System, Structure or Component) SSC, the failure to previously identify these issues does not constitute an actual TS inoperability. Rather, the issues identified during this MSO are noncompliances with the Current Licensing Basis (CLB). Therefore, the affected systems are considered operable but degraded or non-conforming as defined in Regulatory Issue Summary (RIS) 2005-20.</br>The licensee has notified the NRC Resident Inspector.e has notified the NRC Resident Inspector. +
