| ENS 45883 | 30 April 2010 05:26:00 | At 0300 (CDT) on 04/30/2010, the Plant Computer Group identified that the SPDS stalled and was not updating data points as required. The SPDS also supplies data to several Emergency Response Data System (ERDS) points. Redundant, normal control room indications are still available to the operators. This is considered a Loss of Emergency Assessment Capability and therefore, reportable under 10CFR50.72(b)(3)(xiii). SPDS was restored at 0356 (CDT) on 4/30/2010. The licensee has notified the NRC Resident Inspector. |
