50-247 UNIT Unit No. 2 DATE 3-3-78 COMPLETED BY J. Makepeace TELEPHONE 914-739-8823 Summary of Operating Experience - February, 1978 Unit No. 2 operated at full power, with an output of approximately 830 MW, until February 3, 1978, when a turbine runhack to about 500 MW occurred as the result of the failure of a sumner unit as-sociated with a bistable in the overpower delta-T circuitry.

Fol-lowing a return to power, another turbine runback occurred at 0029 hours3.356481e-4 days <br />0.00806 hours <br />4.794974e-5 weeks <br />1.10345e-5 months <br /> on February 10, 1978, which was caused by an electrical dis-turbance originating at Buchanan Substation when a pothead on trans-former No. 1 blew.

The electrical disturbance in turn caused a false indication of a dropped rod (Channel 44) with a resultant turbine runback to 70% (approximately 550 MW).

The operators had to further reduce load to approximately 400 mG because of pro-blems with low vacuum in the main condenser.

At approximately 2200 hours0.0255 days <br />0.611 hours <br />0.00364 weeks <br />8.371e-4 months <br /> on February 12, 1978, a load reduction was initiated in preparauien for removing the Unit from service for a scheduled refueling outage.

At 0018 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> on February 13, 1978, Unit No. 2 was removed from service for the Cycle 2/3 refueling outage.

At the time the main generator breaker was opened, the Unit had completed over 118 days and 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> of continuous on-line-generation.

This run was a re-cord for large, 4 loop, PWR reactors, surpassing the previous re-cord of 118 days, 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 5 minutes held by Commonwealth Edison's Zion 2 unit.

Immediately after shutdown, special metal impact monitoring system (MIMS) pump transient data was collected by Westinghouse relative to the loose object in the RCS.

Following this, the RCS was cooled down to approximately 125*F and depressurized for iodine spiking.

On February 15, 1978, the RCS was repressurized to about 425 psig and RCP's 21 & 23 placed in service for system cleanup.

Draining of the secondary side of the four nuclear steam genera-tors was started on February 15, 1978, and completed the follow-ing day.

This draining was done to permit modification, cleaning and inspection work on the secondary side.

Docket No. 50-247 Summary of Operatinc Experience - February, 1978 (Cen t ' d. )

The reactor was maintained in the cold shutdown condition with two RCP's (No. 21 & No. 23) in service for system cleanup until February 24, 1978, at which time both pumps were shut down prior to depressurization of the RCS and drain down.

Inmediately prior and during pump shut down, Westinghouse personnel collected additional data on the MIMS equipment, relating to the loose ob-ject know to exist at the bottom of the reactor vessel.

Drain down of the RCS to the nozzle area was accomplished on February 25, 1978.

The Unit remains in the cold shutdown condition as preparations continue for the Cycle 2/3 refueling activities.
