| Title | Inadequate Procedures for Inspection of Fire Barriers |
| Description | The inspectors identified a Green, NCV of Operating License Condition 2.C.(18), Fire Protection Program, for failure to adequately establish a surveillance procedure for fire penetration inspections. The licensee entered the problem into their corrective action program (CAP) as condition report, CR -17-04029. The inspectors used IMC 0612, Appendix B, Issue Screening, dated September 7, 2012, and determined that the performance deficiency ( PD ) was more than minor and therefore a finding because it was associated with the Mitigating System Cornerstone and the respective attribute of protection against external factors (fire). This finding had a credible impact on safety and adversely affected the cornerstone objective because STP -728.043 failed to specify adequate inspection of penetrations added by modification of which one penetration (5045) was degraded. The inspectors used IMC 0609, Appendix F, Fire Protection Significance Determination Process, dated September 20, 2013, and determined that the finding impacted the fire confinement finding category. Based on review of respective Attachment 2, Degradation Rating Guidance Specific to Various Fire Protection Program Elements, dated February 28, 2005, the inspectors determined that the degradation rating was low based on the size of the degradation identified. Specifically, the separation of foam seal material was approximately 3 from the mating conduit surfaces and there was greater than 12 of foam seal material when it was initially installed. As a result, this finding was determined to be of very low safety significance (Green) based on the guidance in IMC 0609, Appendix F, Attachment 1, Fire Protection Significance Determination Process Worksheet, dated September 20, 2013 |
