SUMMARY

Fort Calhoun Station operated at a nominal 1005 power for the month of August,1982. The Plant reduced power to shaut 95% for the weekend of August 7-8 to perform a scheduled Moderator Temperature Coeffient test required by the Technical Specifications. The test went very well and pcwer was returned to a nominal 1005 the night of August 8,1982. During August, Fort Calhoun received new fuel for Cycle 8. In all, 32 new fuel bundles have been received and the unloading, inspecting and storing operations are progressing. Also during August, annual licensed operator requalification train-ing began at the Combustion Engineering simulator in Windsor, Connecticut. Requalification training vill continue through October 8, 1982. One Auxiliary Operator-Nuclear, resigned and one new Operator-Helper was assigned to Fort Calhoun. At the end of August, the Operations Depart-ment was three full time operators short of its approved staffing level. Permanent transfer of two operators to Fort Calhoun from within the District is being pursued. In addition, interviews are being conducted to fill the remaining staff openings. No safety valve or PORV chillengea occurred. A. ?ERh CRIT!CE O!RPACTERISTICC LER Number De f! ciency LER-016 During :teady state power operation, it was noted that the "B" channel of the reactor protective system "hxial Power Distribution" unit had a nega-tive axial chape index setpoint which was out-of-tolerance. The cetpoint had drifted in a ncn-con-servative direction. The "B" channel for Axial Power Distribution was bypassed and a maintenance order van written to investigate the problem. Throughout the incident, the redundant RPS Axial Power Distribution channels (A, C & D) reme.ined operable and available to perform their des ign function of initiating a reactor trip if ne cessary.

RESULTS OF SURVEILLA'!CE TESTS A'ID INSPECTIONS Surveillance tests as required by the Technical Specifications Section 3 0 and Appendix B, were performed in accordance with the annual surveillance test schedule. The following is a summary of the surveillance tests which resulted in operations Incidents and are not reported elsewhere in the report: Operations Incident Deficiency 01-1570 ST-RM-2 Failed Fuel Monitors, RM-1 & RM-2 not calibrated on return to power.
