MR Number: 1-01-0003 Limerick 2 Date: 02/26/01 Philadelphia,Pennsylvania SRI Dockets: 50-353 BWR/GE-4 Subject: TECHNICAL SPECIFICATION REQUIRED SHUTDOWN DUE TO SAFETY RELIEF VALVE ACTUATION Reportable Event Number: 37778 Discussion: At 9:19 p.m. on Friday February 23, 2001, shortly after operators began a planned shutdown to repair a safety relief valve (SRV), the SRV unexpectedly opened and remained open until reactor pressure decreased to 130 psig. Operators performed a rapid plant shutdown in accordance with station procedures, implemented applicable emergency operating procedures, and by early Saturday morning placed the unit in cold shutdown. The licensee is continuing its investigation of the cause of the unexpected SRV opening. During replacement of the affected SRV, the licensee found that some of the studs and nuts used in the flange to connect the SRV tailpipe to the SRV had fallen off and some stud/nut combinations in the flange had as-found torque values that were less than the specified torque value of 230 ft-lbs. There was no evidence that the flange joint failed while the valve was open and the licensee concluded that the as-found flange configuration was sufficient to maintain operability. The licensee inspected the SRV tailpipe to SRV flange on all Unit-2 SRVs and found some additional examples of stud/nut torque valves less than the specified value. The licensee preliminarily determined that the torque value was insufficient to prevent relaxation of the bolting pre-load, increased the specified torque value to 300 ft-lbs, and re-tightened all stud/nut combinations to the higher torque value. Regional Action: The resident staff continues to follow the licensee's actions in response to this event.
