SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 8 TO FACILITY OPERATING LICENSE NPF-68 GEORGIA POWER COMPANY, ET AL.
DOCKET NO. 50-424 V0GTLE ELECTRIC GENERATING PLANT, UNIT 1 1.0 INTRODUgION By letter dated February 4,1988, Georgia Power Company, et al., (the licensee) requested a change to the Technical Specifications for Vogtle Electric Generating (VEGP), Unit 1.
Plant,(TS) by deleting the control building sump effluent line radiationThe proposed c tions monitor, RE-17646, 2.0 EVALVAHON The proposed amendment deletes monitor RE-17646 from TS Table 3.3-9, "Radioactive Liquid Effluent Monitoring Instrumentation," and from TS Table 4.3-5, "Radioactive Liquid Effluent Monitoring Instrumentation Surveillance Requirements."
In support of this change, the licensee has provided the following information:
Radiation monitor RE-17646 is a part of the Process and Effluent Radiation Monitoring System (PERMS) and functions to minimize the release of radioactive liquid effluent from the control building sump. As a result of a recent piping modification, this function can now be performed by another PERMS monitor.
In the original piping configuration, the normally non-radioactive discharge from the control building sump was monitored by RE-17646 then tied in to the turbine building drain header at a point downstream of radiation monitor RE-0848.
A high radiation signal from RE-17646 would cause isolation of control building sump discharge flow into the turbine building drain header.
The piping has been modified so that the cuntrol building sump discharge now ties in to the turbine building drain header upstrea:n of RE-0848. Detection of high radiation by RE-0848 causes automatic diversion of drain header flow from its normal flow path (to the oily waste separator, then the waste retention basin, and then the blowdcsa sump) to the "dirty" turbine building drain tank.
Monitor RE-17646 is not necessary for the mitigation of any accident analyzed for Plant fogtle.
Since RE-0848 now provides for minimizing radioactive discharge from the control building sump, RE-17646 can be deleted with no safety consequences. Georgia Power Company is proposing to delete RE-17646 to reduce the manpower commitment and expense required for maintenance and surveillance.

-2 The NRC staff hds reviewed the above information and finds that monitor RE-0848 will function adequately to minimize radioactive otscharge from the control building sump.
Therefore, monitor RE-17646 is no longer needed, and the NRC staff concludes that this change is occeptable.
3.0 ENVIRONMENTAL CONSIDERATION
This amendment involves a ch6nge in a requirement with respect to installation of o facility component located within the restricted area as defined in 10 CFR Part 20. The staff has determined that the amendmen involves no significant incre6se in the amounts, and no significant change in the types, of dny effluents that may be released offsite, and that there is no significant increase in individual or cun.ulative occupational exposure.
The NRC staff has made a determination that the amendment involves no significant hazards consideration, and there has been no public coment on such finding. Accordingly, the amendment meets the eligibility Criteria for Cdtegorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepored in connection with the issuance of the amendtnent.
4.0 _ CONCLUSION The Consnission made a proposed determination that the amendment involves no significant hazards consideration which was published in the Federal ReLster i
on April 20,1988, (53 FR 13016), and consulted with the state ToTINioFgia. 70 public comments were received, and the state of Georgia did not have any comments.
The staff has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safet endangered by operation in the proposed manner, and (2)y of the public will not be such activities will be conducted in compliance with the Comission's regulations, and the issuance of this amendment will not be inimical to tne comon defense and security or to the health and safety of the public.
