NRC CAL – NOV (White)

On December 8, 2011, the NRC issued a White Significance Determination Process finding and a Notice of Violations for two violations to Exelon Generation Company, LLC. as a result of inspections at the Limerick Generating Station, Unit 2. The White finding was based on the failure to ensure that sufficient technical guidance was contained in an operating procedure. This failure resulted in two valves failing to fully shut, which rendered two reactor systems inoperable for greater than the Technical Specification allowed outage time. The two violations are based on the Licensee’s failure to: 1) establish adequate procedures; and, 2) exceeding Technical Specifications for two reactor systems.
