| Title | Failure to Adequately Evaluate and Correct a Failed Open Level Control Valve in the Moisture Separator Drain System |
| Description | A finding of low to moderate safety significance wa
identified where engineering staff did not properly evaluate and correct degraded level control valve for the i12Ai12 moisture separator drain tank, as require by station procedures. In addition, engineers did not properly consider a simila occurrence from 1988. The level control valve failed 25 days prior to the even and caused the moisture separator drain system to operate in a condition outsid its design. As a result, an 8-inch pipe in that system failed and caused the even on October 10, 2004 This issue is greater than minor because it is associated with the Equipmen Performance attribute of the Initiating Events cornerstone and affected th objective of limiting the likelihood of events that upset plant stability an challenge critical safety functions. A Significance Determination Process Phas 2 risk analysis determined that this finding had low to moderate safet significance based on the increased frequency of a transient with the loss of th power conversion system initiating event over the 25-day exposure period.
