Proposed Technical Specification Change Propcsed Chenge '

Reference is made to Pilgrim Nuclear Power Station, Unit #1 Technical Specification, Appendix A, Section 3.7. A, " Primary Containment", Item 3.7. A.4.a(3).

Remove the following: 3.7.A.4.a(3)

"The position alann... opening exceeds 3/32".

Add the following: 3.7.A.4.a(3)

"Neither of the two position alarm systems which annunciate on Panel C-7 and Panel 905 when any vacuum breaker opening exceeds 3/32", are in alarm."

Remove the following: Item 4.7.A.4.a(3)

"Until such time...shall be performed."

-Remove the following: Bases 3.7.A and 4.7.A "Each dry-well suppression... longer be applicable."

Add the following: Bases 3.7.A and 4.7.A Each drywell suppression chamber vacuum breaker is equipped with three switches. One provides full open indication only. Another provides closed indication and an alarm on Panel C-7 should any vacuum breaker come off its closed seat by greater than 3/32". The last provides a separate and redundant alarm on Panel 905 should any vacuum breaker come off its closed seat by greater than 3/32". The two alarms above are those referred to in Section 3.7. A.4.a(3) and 3.7. A.4.d.

Reason for Change A change to Item 3.7.A.4.a(3) will clarify the ambiguous language that now exists. Specifically the words "when installed" are deleted and the proposed change details the applicable Drywell to Torus Vacuum Breaker alarms. ,

i Item 4.7.A.4.a(3) is no longer needed because the position indicators with alarm in the control room are installed on the drywell-pressure suppression chamber vacuum breakers.

Safety Considerations

This change does not oresent an unreviewed safety question as defined in 10 CFR 50.59(c). It has been reviewed and approved by the Operations Review Committee and reviewed by the Nuclear Safety Review and Audit Committee.

Schedule of Change This change will be put into effect upon receipt of approval by NRC.

Fee Determination Pursuant to 10 CFR 170.22 Boston Edison Company proposes this change as Class II.
