| Title | Licensee-Identified Violation |
| Description | Title 10 CFR Part 50, Appendix R, requires, in part, that one train of systems necessary to achieve and maintain hot shutdown conditions from either the control room or emergency control station is free of fire damage. On January 14, 2009, the licensee identified an Appendix R non-compliance in that IA would not be free of fire damage to support safe-shutdown (see Section 4OA3.2). However, existing procedures provided guidance to operators for replacing back-up compressed air cylinders, as necessary, to maintain IA capability. The licensee performed a safety significance evaluation and determined that the issue was not of high safety significance based on the ignition sources and the effectiveness of the automatic and manual suppression in the area. The inspectors concurred with the overall results of the licensees evaluation for safety significance. This issue met criteria for enforcement discretion under Interim Enforcement Policy Regarding Enforcement Discretion for Certain Fire Protection Issues (10 CFR 50.48) published in Federal Register Notices dated June 16, 2004; January 14, 2005; and April 18, 2006. |
