MONTHLY OPERATING ACTIVITIES - MAY 1983

,ll Highlights:

,'a,,

si L The Unit entered the reporting period operating it 100% power and remained //

in service for the entire reporting period. Ther'e were five power '

'?

reductions with return to 100%. These are detailed in the Summary.

/'l Total electrical generation was 816,880 MWH.-

f' Summary:

,I >

5/3/83 Unit power reduction was initiated at 0916 nours. Train"B"ofthe)[

Solid State Protection System (SSPS) of Reactor Protection had bee 6 bypassed for 58 minutes for surveillance testing and it was evident that the testing would exceed the G hour allowed by the Technical Specifications. The testing had id_entified a problem with one of the Solid State Boards. The failed board was identified, replaced

/

and tested. The Reactor Protection System was returned te normal at 0924.

Power reduction had been less than 1% by this time, so the' Unit was immediatelv reloaded to 100%.

j

,i 1 5/4/83 Reactor power suddenly reduced to 97% at 0910 hours0.0105 days <br />0.253 hours <br />0.0015 weeks <br />3.46255e-4 months <br /> as the Boron

j{

Injection Tank (BIT) was being'. test pressurized.

It was immediately realized that the power reducti,oh was due to leak through of Boric jr[

Acid from the BIT and the pressurization stopped. Further testing

' l indicated that the pressurization had been performed too s1owly.

A more rapid pressurization causLJ the BIT outlet valvfs to -seal off t ~ J ~

Reactorpowerwasreturnedtoj00%. Total time below 100% was 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.

9 5/5/83 The East Residual Heat Renoval Pump and the North Safety Injection '

PumpweredeterminedtobeinoperablebytheInServiceInspect)3on r

j (ISI) Program. These pumps were in this inoperable status for-hours while they were retested ar.d found to be within the limits '

/

of the ISI Program.

5/13/83 Unit power was reduced to 54%.over a 1-3/4 hour ramp starting at 2200 hours0.0255 days <br />0.611 hours <br />0.00364 weeks <br />8.371e-4 months <br />. The East Main Feedpump was removed from service to drain, clean and refill the Turbine Hydrauli^c Fluid Reservoir. _

n This cleaning and replacement had beccme necessary due to the Hydraulic Fluid becoming contaminEted by inleakage of lubricacing oil. WhiletheTurbine/Pumpwsou(ofserviceaHydraulicrelay '

that interfaces the Hydraulic Fluid and Lubricating 011 Circuits.

was replaced because it was suspect.ed..of cross-leakage.

5/15/83 The East Main FeedpuMp was raturned tv, service at 0245 hours0.00284 days <br />0.0681 hours <br />4.050926e-4 weeks <br />9.32225e-5 months <br />, but-loading was maintained at the 54% level due to low customer demaid. -
