PROPOSED CHANGE TO TECHNICAL SPECIFICATIONS UNIT NOS.- 1 AND 2 Description of Change LCR 85-20 In Table 3.3-10 of Section 3/4.3 of the Technical Specifications, increase the number of installed detectors and minimum required operabl~ for the Control Room Area as.shown* on the attached pag,e revisions.

Reason for Change Our original commitment in response to Appendix R was to add fire detection capabilities to the peripheral areas of the tontrol Room.

This commitment was subsequently determined to*be unnecessary on the basis that those areas that were continuously occupied did not require fire detection capabilities.

This -

resulted in the addition of detectors to the Auxiliary Equipment Room only.

As a result of an NRC inspection, it was concluded that this did not completely address 10CFRSO Appendix R requirements.

Therefore, additional detectors have been added to the peripheral areas of the Control Room resulting in -the changes

(~

to the Technical Specifications described above.

\\

SIGNIFICANT HAZARDS CONSIDERATION EVALUATION This change constitutes an additional limitation, in that it adds additional fire detection instruments to a table of instruments required to be OPERABLE.

This corresponds to example (ii) of the guidance provided by the Commission, in Federal Register 48FR14870, for Amendments That Are Considered Not Likely To Involve Significant Hazards Considerations.

Based on the above, and on our determination that operation of the Salem plant with the requested changes in place would not increase the probability or consequences of any previously analyzed acc:tdent, would not_ create the possibility for any new accident, and, by adding-additional instrumentation to detect fires, will increase the margin of safety, we deem that this change does not involve a significant hazards consideration.
