Finding

Title

Licensee-Identified Violation

Description

On February 15, 2010, the licensee failed to enter TS LCO 3.7.10 ECCW System, as required, when an unisolable leak was identified on piping associated with the ECCW B subsystem. The cause was a failure to complete a timely evaluation of the leaks impact on operability of ASME Class 3 system piping. This was identified in the licensees CAP as CR 10-71622. Corrective actions included taking appropriate TS actions as required when the operability impact was identified at 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br /> and 40 minutes after the initial identification of the piping leak. Additional actions include plans to improve operator training in the area of timely and correct operability determinations. The violation was determined to be of low safety significance through a licensee-conducted probabilistic risk assessment evaluation.
