Technical Specifications require that refuel floor high exhaust radiation monitors be operational during the movement of irradiated fuel. Specifically, TS tables 3.3.6.2-1 and 3.3.7.1-1 requires radiation monitors be operational for conditions such as
core alterations and during movement of irradiated fuel assemblies in
secondary containment. Contrary to these requirements, on February 5, 2008, irradiated fuel moves were performed (six irradiated bundles) with both the Unit 1 and Unit 2 refuel floor high exhaust radiation monitors bypassed. The function of the high exhaust radiation monitor instrumentation is to initiate systems that limit fission product release during and following postulated fuel handling accidents. This issue is captured in
PPLs corrective action program as CR 967350. NRC management determined this finding to be of very low safety significance because no event occurred that would require the high radiation monitor interlocks to function; the time period of TS inoperability was brief (less than a
12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> shift); and all other preventive and mitigation features for the postulated design basis fuel handling accident remained available
