Finding

Title

Licensee-Identified Violation

Description

Unit 2 Technical Specification 3.8.7, Electrical Distribution System Operating, required that the AUTO/MANUAL transfer switch on the 2D RMOV Board be in AUTO to maintain the board operable, otherwise declare the associated RHR subsystem inoperable. TS LCO 3.5.1, Emergency Core Cooling System Operating, required that Unit 2 be placed in Mode 3 in 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months and Mode 4 in 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months if one low-pressure ECCS subsystem is inoperable for greater than seven days. Contrary to this, the licensee discovered during routine surveillance testing that the automatic transfer switch on the 2D RMOV Board was inadvertently left in the MANUAL position between June 19, 2009, and July 18, 2009, without taking the TS required action specified above. This TS violation was entered in the licensees CAP as PER 176648. The finding was determined to be of very low safety significance because it did not constitute a total loss of safety function since Division II of LPCI would have been available during an accident
