Summary of Operating Experience April 1988 l L

^

[

The plant entered the month in Mode 1 at 100% power. {

i On April 5, the 'B' centrifugal charging. pump developed a

! significant leak through its mechanical shaft seal. The pump was a removed from service and isolated'to stop the leak. The pump was ,

repaired and returned to service on April 7.

. On April 7 at 0436 hours0.00505 days <br />0.121 hours <br />7.208995e-4 weeks <br />1.65898e-4 months <br />, a turbine runback reduced power to 72%.

The runback was caused by loss of the generator stator cooling pumps due to loss of their electrical power. Power was restored  ;

l to 100% at 0815 hours0.00943 days <br />0.226 hours <br />0.00135 weeks <br />3.101075e-4 months <br />.

Power reduction for the 1988 refueling shutdown was begun at 1800 >

j on April 12. The turbine generator was removed from service at  :

0019 hours2.199074e-4 days <br />0.00528 hours <br />3.141534e-5 weeks <br />7.2295e-6 months <br /> on April 13 and the. reactor shutdown at 0021, placing j the plant in Mode 3.

On April 13, pressurizer safety valve 8010C setpoint was found to ,

i be lower than its Technical Specification allowed value during i safety valve testing. The setpoint was adjusted, Gnd the valve [

was retested satisfactorily.

i Plant cooldown and depressurization was begun o's April 13 at 2325 l hours. The plant entered Mode 4 at 0535 on Apr il 14 and Mode 5 at- -

0627 on April 15. The reactor vessel head was detensioned on l April 20 at 2235, placing the plant in Mode 6. As of April 30, the plant remained in Mode 6 with unloading of fuel from the

reactor vessel in progress.
