JOSEPil M. FARLEY NUCLEAR PLANT UNIT 2 NARRA11VE SLM MRY Of OPERATIONS August 1991 There was one reactor trip during the month of August. At 1704 on August 6, while operating at approximately 100 percent power, a reactor trip occurred. Apparently, a lightning induced transient in the rod conirol system caused some of the control rods to drop which resulted in a negative flux rate reactor trip. Testing and inspection of the rod control system revealed no damage. All power susply voltages were normal and the surge suspressor on the rod control power ca)inets backup power supplies was found to se functioning properly. All control rods were exercised several times and the operability of the rod control system was verified per FNP-2-STP-5.0 (full Length Control Rod Operability Test) and TNP-0-ETP-3643 (Verification of Rod Control System Operability). The following major safety-related maintenance was performed during the month: 1. 2E Service Water Pump and Motor was replaced on 8-15-91 and returned to service on 8-22-91. 2. 2B Service Water Pump was replaced on 8-27-91 and returned to service on 8-28-91. 3. Miscellaneous corrective and preventive maintenance was performed on the diesel generators. 1 l l File:mm/licens/nrc-mont
