SUMMARY OF FINDINGS Callaway Plant NRC Inspection Report 50-483/02-09 IR 05000483-02-009; on 08/12/2002-08/16/2002; Union Electric Co; Callaway Plant Supplemental Inspection Report This inspection was conducted by the Chief, Technical Support Staff, a Project Engineer, and an Engineering Associate. The inspection was performed to independently verify that adequate corrective actions had been taken for the White finding identified in NRC Inspection Report 50-483/02-07. The White finding involved the corrective actions taken to address the on-demand failure of an auxiliary feedwater pump to start. The inspection did not identify any safety significant findings. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described at its Reactor Oversight Process web site at http://www.nrc.gov/NRR/OVERSIGHT/index.html.

Cornerstone: Mitigating Systems The NRC performed this supplemental inspection to assess the licensees corrective actions associated with the inoperability of a motor-driven auxiliary feedwater pump. This performance issue was previously characterized as having low to moderate risk significance in NRC Inspection Report 50-483/02-07. During this inspection, the NRC concluded that the licensee had effectively identified and implemented corrective actions for the root and contributing causes for the inoperability of the auxiliary feedwater pump. Based on effective implementation of the corrective actions, it appeared that the inoperability of the pump as a result of foam being entrained in the suction of the pump was adequately addressed.

The effectiveness of the overall corrective action program changes documented in NRC Inspection Report 50-483/02-09, and the licensees letter to NRC, dated May 8, 2002, will be reviewed during the Problem Identification and Resolution inspection, currently scheduled for December 2002. The performance issue associated with the White inspection finding will remain open until that review is completed.
