24 - HR CONDITION OF LICENSE REPORT DUE TO T.S. NOT MET
The licensee provided the following information:
"On March 29, 2005, Seabrook determined that the requirements of T.S. 3.8.1.1 were not met when the Reserve Auxiliary Transformer (RAT), AC supply to the Bus E5, was removed from service on February 14, 2005. T.S. 3.8..1.1, Action a. requires that the operability of the remaining AC power source be verified within 1 hour, and at least once every 8 hours thereafter. This action requirement was not completed on February 14, 2005 when the RAT AC power supply to Bus E5 was removed from service. At the time of this event the unit Auxiliary Transformer AC power supply to Bus E5 and E6, and the RAT AC power supply to bus E6, were in service. This event is reportable pursuant to Seabrook Station license, Condition 2.G., as a violation of the Technical Specifications.
The licensee notified the NRC Resident Inspector.

ACTUATION OF THE REACTOR PROTECTION SYSTEM AND AUXILIARY FEEDWATER SYSTEM WHILE ESTABLISHING INITIAL CONDITIONS FOR LEAK TEST IN MODE 3.
The licensee faxed the following information:
"On 3/29/05, with the Callaway plant at 0 % power in Mode 3, Steam Generator (S/G) levels were being maintained using 'B' Condensate Pump. Reactor Coolant System (RCS) temperature was being controlled using Condenser Steam Dumps. Preparation was in progress for performance of a leak test on Main Feedwater Isolation Valve AEFV0041. As part of the leak test, condensate flow was temporarily isolated to 'C' S/G and the Auxiliary Feedwater System was aligned to provide water to the 'C' S/G. When low was initiated to 'C' S/G using auxiliary Feedwater, level initially increased due to the injection of a small volume of warm water contained within the Feedwater piping at the S/G, then proceeded to rapidly decrease due to S/G shrink caused by the injection of Auxiliary Feedwater with a temperature of approximately 70 degree F. Level in 'C' S/G decreased until S/G Lo Lo Level reactor trip and Auxiliary Feedwater Actuation signals were generated. Performance of the leak test was terminated and RCS temperature and S/G levels were stabilized at normal parameters for Mode 3."
The licensee informed the NRC Resident Inspector.
