| Title | Degradation of 3-hour fire Barrier |
| Description | The inspectors identified a finding of very low safety significance (Green) and an associated non-cited violation (NCV) of license condition 2.C.(3), Fire Protection, for failure to maintain a three hour barrier between two safety-related rooms. Specifically, the inspectors noted a through-wall crack in the three hour fire wall between the 1-1 and 1-2 diesel rooms. The licensee entered the issue in the corrective action program (CAP) as CR-PLP-2008-02696, and repaired the crack. The finding is more than minor because it is associated with the protection against external factors (fires) attribute of the mitigating system cornerstone and affected the objective to maintain the reliability and capability of systems that respond to events to prevent undesirable consequences. In accordance with IMC 0609, Appendix F, Fire Protection SDP, the inspectors conducted a Phase I SDP screening. The inspectors determined the finding is of very low safety significance (Green), because the fire areas had fully functional, automatic water-based fire suppression, which provided adequate coverage in both rooms and no transient combustible loads were present in either room.
