OF OPERATING EXPERIENCES Umerick Unit 2 began the month of October at a nominal 100% of rated thermal power On October 4, reactor power was briefly reduced to 91% to perform Main Turbine Control Valve testing and a i Control Rod. pattern adjustment. On October 15, an inadvertent trip on the '2A' Reactor i
, Recirculating Pump was experienced while performing a surveillance test, this caused a reactor j , power decrease to 16.5%, Reactor Power was restored to a nominal 100% on October 16.' On >
