Salem Generating Station, Unit 1 Public Service Electric & Gas Company Hancocks Bridge, New Jersey 08038 IDENTIFICATION OF OCCURRENCE:

Nos. 11 and 12 Boric Acid Transfer Pumps - Inoperable.

This report was initiated by Incident Report 82-124.

CONDITIONS PRIOR TO OCCURRENCE:

Mode 1 - Rx Power 87% - Unit Load 960 MWe.

DESCRIPTION OF OCCURRENCE:

The pumps were declared inoperable, and with no operable pump in the boron flow path, Technical Specification Action Statements 3.1.2.2.a and 3.1.2.6 were entered.

DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:

The BATP flows had decreased due to an increase in impeller to volute clearance whien resulted from normal wear.

ANALYSIS OF OCCURRENCE:

This occurrence led to operation in a degraded mode permitted by a limiting condition for operation, and is reportable in accordance with Technical Specification 6.9.1.9.b.

Boration capability existed through the flow path from the Refueling Water Storage Tank via a charging pump.

Consequently, no risk to the health or safety of the general public was involved.

Action Statement 3.1.2.2.a requires:

With the flow path from the boric acid tanks to the Reactor Coolant System inoperable, restore the inoperable flow path to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, or be in at least hot standby and borated to a shutdown margin equivalent to at least 1% delta k/k at 200 F within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

Lg < 82-032/03L 6 ANALYSIS OF OCCURRENCE (continued) :

Action Statement 3.1.2.6 requires:

With no boric acid transfer pump operable, restore at least one boric acid transfer pump to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, or be in at least hot standby within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and borated to a shutdown margin equivalent to 1% delta k/k at 200 F.

CORRECTIVE ACTION

No. 11 BATP impeller clearance was adjusted and the pump was satisfactorily tested.

The pump was declared operable at 0610 hours0.00706 days <br />0.169 hours <br />0.00101 weeks <br />2.32105e-4 months <br />, May 16, 1982, and with one operable pump in the boron flow path, Action Statements 3.1.2.2.a and 3.1.2.6 were terminated.

No. 12 BATP subsequently tested satisfactorily, and was declared operable on May 19, 1982.
