Title	Reactor Manually Tripped from 20% Power During Load Reduction.
Event Description	Unit 4 reactor was manually tripped from 20 percent power per 4 - GOP - 103 "Power Operation to Hot Standby" (normal shutdown procedure), during a load reduction to take the unit off line. The reason for the load reduction was an oil leak of approximately 100 drops per minute on the "4B" steam generator feed pump. The reactor was tripped when directed by 4 - GOP - 103. All rods fully inserted, no relief valves lifted, and all other systems functioned normally. The licensee notified the NRC Resident Inspector. * * UPDATE FROM V. BARRY TO M. RIPLEY 1125 EST 03/24/05 * * * The licensee provided the following information via facsimile (licensee text in quotes): Upon review, the manual reactor trip from 20 percent power is not reportable in accordance with 10 CFR 50.72(b)(2)(iv)(13) since it was part of the pre-planned sequence of reactor shutdown steps contained in procedure 4-GOP-103, "Power Operation to Hot Standby." In addition, the reactor shutdown was not required by Technical Specifications. The NRC Resident Inspector will be notified of this retraction.
