DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:

Personnel Error -

The Control Operator had given instructions to open the supply valve, but not in sufficient time to prevent the temporary loss of required level in the tank.

ANALYSIS OF OCCURRENCE:

In the process of using the AFWST as a makeup supply of water to the steam generators, the supply valve for the AFWST was throttled too far to compensate for the water removed.

CORRECTIVE ACTION

The tank was refilled to > 200,000 gallons of stored water and the Action Statement was terminated at 1040 hours0.012 days <br />0.289 hours <br />0.00172 weeks <br />3.9572e-4 months <br />.

The Control Operator has been counseled for his error in judgment.
