CORRECTED PAGE standby power converter unit, and switching modules with new equipment rated at 50 kVA. The UPS system modification is scheduled to be completed for Unit I during the current refueling outage.
The proposed modification of the UPS system (50 kVA) was evaluated for its impact on the DC battery load study. The loads fed from the UPS power con-version module are not altered by this modification. However, there is an increase in the load from the batteries due to a decrease in the efficiency of the new 50 kVA system. Even with the additional 20 amp increase, the configuration of two lighting inverters is a conservative loading of the B division battery and bus. The loading of the power conversion modules does not exceed the combination of the greatest load on the battery system which was used for the load study. While the capacity margin of the batteries is slightly reduced, the proposed modification has been bounded by the 1984 battery load study. The proposed change to Surveillance Requirement 4.8.2.3.1.(b) to delete reference to 37.5 kVA power conversion modules and to clearly add a definition of the load configuration is ac-ceptable.
3.0 ENVIRONMENTAL CONSIDERATION
S An Environmental Assessment has been prepared pursuant to 10 CFR Part 51.32 and published in the FEDERAL REGISTER on May 27, 1987 at 52 FR 19787.
4.0 CONCLUSION
The Commission has issued a " Notice of Consideration of Issuance of Amend-ments to Facility Operatir.g Licenses and Opportunity for Prior Hearing" which was published in the FEDERAL REGISTER (51 FR 44158) on December 8,1986, and consulted with the State of North Carolina. No public coments or requests for hearing were received, and the State of North Carolina did not have any coments.
We have concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities vill be conducted in compliance with the Com-mission's regulations, and the issuance of the amendments will not be inimical to the comon defense and security or to the health and safety of the public.
