REPORTABLE OCCURRENCE 251-81-1 LI'CENSEE EVENT FIPORT PAGE TWO Additional Event Description and Probable Consequences During startup, for a period of about 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, the condensate storage tank (CST) contained less than the 185,000 gallons required by TS 3.8.1.c.

Unit was under-going low power physics testing after refueling.

Operation in this mode is permitted by TS 3.8.3.

The CST inventory during this interval was not reduced below approx-imately 180,000 gallons. The only effect of having a reduced volume in the CST is illustrated in FSAR Figure 9.11-1.

The event had no effect on public health and safety. Previous occurrences of low CST levels from various causes have been reported as: LER 250-78-4, LER 250-78-11, LER 250-78-12, LER 250 '8-13, LER 250-79-11, LER 250-79-29, LER 250-80-2, LER 251-78-7, LER 251-78-13, LER 251-78-14, LER 251-79-17, LER 251-80-2, LER 251-80-4.

Additional Cause Description and Corrective Actions There were no equipment functional problems associated with this event.

Increased water demand during low power physics testing exceeded water treatment plant output and resulted in CST level decreasing to less than the TS 3.8.1.c limit.

Plant changes and modifications currently scheduled will reduce the potential exposure to events of this type. Additional water storage capacity is being provided as a part of the planned upgrade of the demineralized water /deareation system. This modification is currently scheduled to be completed during the -

second quarter of 1981. A steam generator blowdown recovery systcm will be installed on each of the nuclear units.

This modification is currently scheduled to be I

completed during the steam generator replacement outage on Unit 4 during the second quarter of 1982 and on Unit 3 during the second quarter of 1983.
