OPERATIONS SUMARY MARCH,1987 The unit entered March in a refueling shutdown condition with fill of the Reactor Coolant System (RCS) in progress.

On March 1,1987 the RCS was filled and by March 3,1987 a 40# steam bubble was established in the pressurizer.

On March 2, during electrical preventive maintenance in the 1 "A" Auxiliary Transformer Control Cabinet, an electrician, while attempting to rectify an improperly installed relay cover, caused the 1 "A" auxiliary transformer to trip. This, in turn, caused the 1 "B" Emergency Diesel Generator to start and load. There was no major safety significance associated with the auto start of the Emergency Diesel Generator.

LER 87-002 provided details of this event.

On March 12, 1987, there was a small release of chlorine gas from the river water chlorinator system. The event occurred during a scheduled switchgear outage and restoration evolution. The root cause has been determined to be lack of procedural guidance. There was no environmental impact as a result of this relatively small gas release. This event was not reportable and no LER was processed.

The plant proceeded to heatup on March 20 reaching hot shutdown at 2140 on that date. An integrated remote shutdown system test was successfully completed on March 22, 1987. Following Heat Sink Protection System (HSPS) testing, the system was enabled (except high OTSG level isolation) to support power operation.

The reactor was taken critical and low power physics testing commenced on March 23, 1987.

Following low power physics testing and overspeed testing of the main turbine, the plant proceeded to approximately 81% reactor power whereby it is limited by indicated high OTSG levels (72%

"A"; 90% "B").

The plant remained at approximately 81% power whereby it is limited by high OTSG levels for the remainder of the month. HSPS high level isolation remains bypassed.

MAJOR SAFETY RELATED MAINTENANCE During the month of March, TMI-l was completing the scheduled 6R refueling outage and restoring plant cleanliness and returning systems to normal for l

plant startup.

The following major maintenance items were performed:

Local Leak Rate Testing - Local Leak Rate Testing (LLRT) was performed on Valves CA-V-1, 2, 3, 5, A/B,13; SA-V-2, 3: Penetrations 104, 105, 106, 210, 211; Reactor Building Fire Service Spool Pieces and AH-V-1 A/B/C/D. All testing was satisfactorily performed.

Heat Sink Protection System (HSPS) - The HSPS OTSG level instrument calibration was a significant work item in March. A vendor representative was present to aid in the calibration effort. The calibration / static alignment work was performed on the startup range transmitters first and then on the operating range transmitters. All of the calibration work was performed to support the plant startup prcgram.

Weekly checks / readings will be taken to verify instrument accuracy for the next several weeks. At that time, a determination will be made for the need to continue these checks / readings.
