ATTACHMENT B TECHNICAL SPECIFICATION CHANGE REOUEST LASALLE COUNTY STATION UNITS 1 and 2 NO SIGNIFICANT HAZARDS CONSIDERATION Commonwealth Edison has evaluated the proposed Technical ,

Specification Amendment and determined that it does not represent a f significant hazards consideration. Based on the criteria for defining a l significant hazards consideration established in 10 CFR 50.92 operation of LaSalle County Station Units 1 and 2 in accordance with the proposed amendment will not:

l l 1) Involve a significant increase in the probability or consequences of an I

accident previously evaluated because:

1 This proposed change of the Technical Specifications is an administrative  ;

change to specify the new compartment location for the normal and 1 emergency 480 VAC circuit breakers. j l l l l

2) Create the possibility of a new or different kind of accident from any accident previously evaluated because:

This proposed change of the Technical Specifications is an administrative change to specify the new compartment location for the normal and l emergency 480 VAC circuit breakers.

1

3) Involve a significant reduction in the margin of safety because:

1 This proposed change of the Technical Specifications is an administrative change to specify the new compartment location for the normal and emergency 480 VAC circuit breakers.

Gaidance has been provided in 51 FR 7744 (reference (c)), for the application of standards to license change requests for determination of the I

existence of significant hazards considerations. This document provides I

examples of amendments which are not likely considered to involve significant hazards considerations. This proposed amendment most clearly resembles example e(i) of those examples deemed not likely to involve a significant hazards consideration. It is purely an administrative change meant to clarify the requirements.
