1.0 DESCRIPTION

OF CHANGE This change,-which is editorial in. nature, is a rewording of the criteria required to demonstrate the operability of the Source Range Monitor (SRM) channels by verifying the SRM count rate. The specific changes are described as follows and shown in Attachment 2.

For Surveillance Requirement 4.3.7.6.c.1, the SRM count rate of "0.7 cps" is changed to "3.0 cps".

Surveillance Requirement 4.3.7.6.c.2 which states, "The signal-to-noise ratio is greater than or equal to 2.0, unless verified within the previous 31 days", is deleted.

The footnote designated by "f" which corresponds to the SRM count' rate.of 3.0 cps in Surveillance Requirement 4.3.7.6.c.1 is revised to read "The count rate may be as low as 0.7 cps if_the signal-to-noise ratio is 22.0.

Similar changes are also proposed for Technical Specification Surveillance Requirement 4.9.2.c.

2.0 REASON FOR CHANGE This change is requested to clarify the count rate required to demonstrate operability of the SRM channels and to delete the redundancy of Surveillance Requirements 4.3.7.6.c.2, 4.9.2.c, and their associated footnotes designated by "f".

There has been no change to the content of these Surveillance Requirements, therefore the criteria for demonstrating SRM channel operability are unchanged.

3.0 BASIS FOR NO SIGNIFICANT HAZARDS FINDING The proposed license change does not involve a significant hazards consideration because operation of the Shoreham Nuclear Power Station, in accordance with this change, would not:

(1) involve a significant increase in the probability or consequences of an accident previously evaluated as the proposed change is a clarification but does not alter the content or criteria of the surveillance requirements.

7- .

. G*

'.O SNRC-1451 Attachment 1 Page 2 of 2 (2) create the possibility of a new or different kind of accident from any accident previously evaluated as the surveillance requirement criteria have not been revised.

(3) involve a significant reduction in a margin of safety as

-the surveillance requirement criteria have'not been revised.

'The Commission has provided guidance concerning the applicability of standards for determining whether a

? significant hazard. consideration exists by providing certain examples (48 FR 14870) of amendments that are considered not likely to involve significant hazards consideration. Example (i) relates to a purely administrative change to the technical specifications.

While the examples given by the Commission do not specifically correlate to this requested classification, LILCO submits that they are essentially the same.

Therefore, based upon the above considerations, and analyses, LILCO has determined that this proposed change does not involve a significant hazards consideration.

4.0 TIMING OF CHANGE Since this change is editorial in nature and does not alter technical content or criteria, LILCO requests that it become effective upon issuance.
