1.0 INTRODUCTION
l By letter dated November 29,1988 and supplemented March 15,1990(W.E. Morgan, Ceco,fication change to delete specific load profiles for eac1 battery andto USN Speci battery char! er for LaSalle County Station Units 1 and 2.
Listings of DC bus load pro iles will be maintained in the Updated Final Safety Analysis Report (UFSAR).
2.0 EVALUATION Specific load profiles for the batteries and battery chargers in the Technical Specifications need to be revised by a supplement each time modifications are added to the DC loads. This change eliminates the need to revise the Technical Specifications every time a DC system load profile change is made by removing the detailed listing of the load profile from the Technical'Specifi-cations. "he DC bus load profiles are presently listed in Tables 8.3-12 through 8.3-14 of the UFSAR. The battery charger specifications are listed in Section 8.3.2.1.1, Unit Class 1E D-C Power System, of the UFSAR. The licenseeannuallyupdatestheUFSARinaccordancewith10CFR50.71(e).
After discussions with the 11censee, a statement was added to the Bases to indicate that the battery load profile and battery charger specifications will be maintained and are located in the UFSAR. The licensee is obligated under 10 CFR 50.59 to have Comission approval if a change in the facility as described in the safety analysis report involves an unreviewed safety question.
This change would make the Technical Specifications similar to the Byron Station Technical Specifications.
The revised pages also reflect format changes to make the Unit 2 Technical Specification pages similar to the Unit 1 pages.

These amendments involve changes to a requirement with respect to the instal-I lation or use of a facility component located within the restricted area as i
defined in 10 CFR Part 20 or a change to a surveillance requireinent. The staff has determined that the amendment involves no significant increase in the I
amounts, and no significant change in the types, of any effluents that may be released offsite and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that this amendment involves no significant hazards consideration and there has been no public comment on such finding. Accordingly, this amendment meets the eligibility criteria for categorical exclusion set i
forthin10CFR51.22(c)(9). Pursuantto10CFR51.22sb),noenvironmental impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.

No public comments were received, and the State of Illinois did not have any coments.
The staff has concluded, based on the considerations discussed aLove, that:
l (1) there is reasonable assurance that the health and safety of the will not be endangered by operation in the prososed manner, and (2) public l
such t
activities will be t:onducted in compliance wit 1 the Commission's regula-tions, and (3) the issuance of these amendments will not be inimical to the common defense and security or to the health and safety of the public.
