REASON FOR CHANGE _

This change to the Technical Specif) cations is proposed to provide an operational flexibility and to utilice the scheduled refueling outage ' for the periodic surveillance requirement of the full-length (shutdren and control) rod drop. times. This Technical Specification Change vill be 1

applicable only to this surveillance interval. and will not affect the l

future surveillance' requirements.

7 DESCRIPTION OF CHANGE 1

Section 4.1.3.3 of the Technical Specifications (Page 3/4 1-21) requires the boa drop time of full-length rods to be demonstrated through measurement

]

prior to reactor criticality at least once' per 18 months. _ Section 4.0.2, l

Applicability of Surveillance Requirements (Page 3/4 0-1), allows the

{

surveillance interval to be extended beyond the specified time as long as the extension does not exceed 25 percent of the specif'ed surveillance interval.

l l

It is requested that this surveillance interval be changed on a single occasion at this time to allow an extension of 2 additional days to complete the scheduled Plant surveillance tast. The increase would be 18 months plus 4.5 months (25 percent) and 2 days. or until midnight April 11,1980.

SAFETY EVALUATION l

1 The time extension proposed in this change for rod drop time surveillance is less than 0.3 percent of the maximus'ellowable time intertal in the l

Technical Specifications.

The individual full-length rod drop times from j

the fully withdrewn position hei.1 been within the Technical Specification limit at Trojac. The probability of this change affecting the rod drop 1

time is extremely remote.

j l

Based upon the above considerecions, another 2 days, e.g., shutting down l

on April 11 vs. fpril 9, is essentially insignificant and would be I

inconsequential from a safety viewpoint. Therefore, it can be concluded i

that there would be no change in the probcbtlity or consequences of accidents previously considered and no new accidents would be created.

j The margin of safety would not be decreased. This change does not involve an unreviewed safety question.

EFFECT ON FSAR This change does not require any changes in the existing FSAR.

j i

i ENVIRONMENTAL EVALUATION l

l The proposed Technical Specification change has no effect on the environ-l ment, the Final Environmental Report or the F1nal Environmental Statement and does not involve an unreviewed environmental question.
