| Title | Licensee-Identified Violation |
| Description | License Condition 2.C(10) specifies that the licensee shall comply with the requirements of the fire protection program as specified in Attachment 4 to the license. The Updated Safety Analysis Report, Section 9B.4.7, specifies, in part, Fire protection features shall be capable of limiting fire damage so that one train of systems necessary to achieve and maintain hot shutdown conditions from either the control room or emergency control station(s) is free of fire damage. Contrary to the above, on May 21, 2007, the licensee determined that they failed to ensure that the Division 1 emergency diesel generator, which was required to achieve hot shutdown, remained operable, hence, free of fire damage under all conditions. Specifically, if service water became unavailable because of a spurious actuation (e.g. valve closure) coincident with a loss of offsite power, the emergency diesel generator could potentially fail prior to transfer of control to the remote shutdown panel. The licensee promptly implemented appropriate compensatory measures and initiated plans to correct the deficiency. The licensee documented this deficiency in Condition Report 2007-02102 and planned to correct the deficiency in 2009. This finding had very low safety significance (Green). This item is further discussed in Section 4OA3.2 |
