| Title | DID Not Provide Adequate Compensatory Guidance to Verify Condensate Storage Tank Operability |
| Description | The inspectors identified a Green finding of very low safety significance when Ginna failed to ensure adequate procedures were developed to support implementation of compensatory measures for a degraded condition associated with the condensate storage tanks (CSTs). The CSTs at Ginna have flexible bladders installed on top of each tank to minimize air infiltration. On March 7, 2007, Ginna discovered that the bladders had degraded which allowed water to accumulate on top of the bladder surface. Ginna performed an operability determination (00) that limited the amount of water that was allowed to accumulate on the bladder surface because it could bias the CST level indication system. The inspectors determined that Ginna did not provide operators with adequate procedures, equipment, and training to verify the 00 leakage limits were met as specified by CNG-OP-1.01-1002, Conduct of Operability Determination/Functionality Assessments, Revision 0000. Ginna \'s corrective actions included increasing the pump down frequency on the CST and verifying the leakage was within the limits specified in the 0 0 . Ginna entered this issue into their CAP for resolution. This finding is more than minor because it affected the equipment performance attribu te of the Mitigating Systems Cornerstone objective of ensuring the availability, reliability and capability of systems that respond to initiating events to prevent core damage. The inspectors determined that the finding was of very low safety significance (Green) because it did not result in a loss of safety function and did not screen as potentially risk significant due to a seismic, flooding, or a severe weather-initiating event. This finding has a cross-cutting aspect in the area of human performance because Ginna did not ensure that complete, accurate, and up-to-date design documentation and procedures were available (H.2.c per IMC 0305) |
