SUMMARY
At the beginning of the month, reactor power was limited to approximately 1500 MWth pending resolution of the 'A" Feedwater Regulating Valve (FRV) control oscillations. On November 4, reactor power was reduced to 889 MWth in preparation for maintenance on the "A" FRV. Following maintenance, full power was achieved on November 5, at 1358. For the remainder of the month, the only other power reductions were for load line adjustments on November 5, 6, 7 and 20.
