j SUMARY OF CHANGES AND JUSTIFICATION This proposal supplements a May 14, 1986 submittal and makes changes to that 4

submittal. The May 14 submittal sought to move two tables (listing secondary i

containment bypass leakage paths and containment isolation valves) from the i

Technical Specifications to the bases and to add three penetrations and update the tables for other planned modifications.

Subsequent discussions have concluded that it is not necessary to add the three penetrations (Outage service penetrations) to the table. This conclusion was reached as these penetrations terminate in the annulus and thus any leakage would exhaust through the annulus ventilation system.

The annulus ventilation system is described in FSAR section 6.2.3 for operation and filters which would minimize any j

actual radioactive leakage through the service penetrations. This portion of the May 14 proposal is thus withdrawn.

l The other changes to the table are the result of an internal audit which determined that several valve designations in Table 3.6-2 (proposed B 3/4.6-2, Containment Isolation Valves) were incorrect. These are summarized below:

Change CF-151A to CF-151B

,l CF-135A to CF-135B NF-233A to NF-233B NM-25A to NM-25AC NV-849A to NV-849AC NM-3A to NM-3AC NM-22A to NM-22AC b

The changes in valve train designations are strictly administrative in nature and j

do not impact plant safety or operation.

ATTACHMENT 3 I

ANALYSIS OF SIGNIFICANT HAZARDS CONSIDERATIONS As required by 10CFR 50.91, this analysis provides a determination that the proposed changes to the Technical Specifications do not involve any significant hazards considerations, as defined by 10CFR 50.92.

i The deletion of the service penetrations from the table requires no significant hazards considerations analysis as this action is simply withdrawing a portion of an earlier, not yet approved, proposal.

Operation in accordance with the proposed change would not involve a significant j

increase in the probability or consequences of an accident previously evaluated.

j The change in valve designations is an administrative matter that causes no j

operational changes were made to the valves; this fact leads to the conclusion

'l that no accident scenarios are affected - in terms of probability or consequences, j

Operation in accordance with the proposed change would not create the possibility of a new or different kind of accident from any accident previously evaluated.

The changes in valve designation are an administrative matter which do not involve any hardware modifications or operational changes.

In the absence of such a change, no new possible accident sequences or scenarios are created.

Operation in accordance with the proposed change would not involve a significant reduction in a margin of safety. The changes in valve designatione are administrative in nature and do not impact plant operations or any operational margins.

4 f

Based upon the preceding analyses, Duke Power Company concludes that the proposed j

changes to the McGuire Nuclear Station Technical Specifications do not involve any l

significant hazards considerations.
