At th~ completion of hot no flow rod drop test, we were unable to restart a Reactor Coolant Pump because pressure could not be main-tained in the Volume Control Tank.

Action Statement 3.4.1.1 was entered_ at 1402 hours0.0162 days <br />0.389 hours <br />0.00232 weeks <br />5.33461e-4 months <br /> which requires with Keff less than 1.0, operation may proceed provided at least one reactor coolant loop is in operation with an associated Reactor Coolant or Residual Heat Removal Pump.*

(* -

The asterisk allows all Reactor Coolant Pumps and Residual Heat Removal Pumps may be de-energized for up to one hour, provjded no.operations are permitted which could cause dilution of the Reactor Coolant System boron concentration.

. DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:

Equipment Failure ANALYSIS OF OCCURRENCE:

At a previous time, the Volume Control Tank relief valve had lifted and the disk became cocked in a partially open position.

When the valve was disassembled, no apparent reason c*ould be found for the disk bei~g cocked and it was decided to replace the internals.

CORRECTIVE ACTION

The valve was removed from the system, inspected and a new disk stem installed.

The valve was tested satisfactorily and reinstalled with the Action Statement being terminated at 1510 hours0.0175 days <br />0.419 hours <br />0.0025 weeks <br />5.74555e-4 months <br /> with a Reactor Coolant Pump being started.
