7b90-01 UNITED STATES NUCLEAR REGULATORY COMISSION GEORGIA POWER COMPANY DOCKET NO. 50-321 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Comission (the Comission) is considering issuance of an exemption from the requirements of Appendix J to 10 CFR 50 to Georgia Power Company (GPC), Oglethorpe Power Corporation, Municipal Electric Authority of Georgia, and the City of Dalton, Georgia, the licensees for the Edwin I. Hatch Nuclear Plant, Unit No.1 (Hatch 1), located in Appling County, Georgia.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:
In accordance with GPC's request dated March 5,1979, the exemption would permit the licensees to leak test the Main Steam Isolation Valves at 28 psig with an acceptance criteria of 11.5 scfh for any valve. Leakage from these valves will not be included in the sumation of the local leak rates.
The Need for the Proposed Action:
10 CFR 50.54(o) requires that primary reactor containments for water cooled power reactors he subject to the i
requirements of Appendix J to 10 CFR Part 50. Appendix J contains the leakage I
test requirements, schedules, and acceptance criteria for tests of the leak-tight integrity of the primary reactor containment and systems and components which penetrate the containment. Appendix J was published on February 14, 1973, and by letter dated August 7,1975, the Comission requested GPC to review the containment-leakage testing program for the facility and to provide a plan for achieving full compliance where necessary.
GPC responded on August 28, 1975, by stating that the containment leak I
rate test program for Hatch I had been reviewed and the program was in full m IB8a Bu8)h l
P
' 7590-01 compliance with Appendix J.
However, in a letter dated November 16, 1977, GPC reported that in formulating a test program for the Edwin I. Hatch Nuclear Plant, Unit 2 (Hatch 2), it discovered that the Hatch 1 program needed to be updated.
Consequently, proposed changes to the Hatch 1 Technical Specifications were also submitted in the November 16, 1977 letter.
In response to GPC's proposed changes, the Commission issued Amendment No. 53 to Facility Operating License No. DPR-57 for Hatch 1 on April 12, 1978.
In its letter of April 12, 1978, the Commission indicated that Amendment No. 53 did not resolve all of GPC's proposed changes but that they would be reviewed as part of the review of the Hatch 2 program.
Subsequently, on March 5, 1979, GPC submitted an updated containment leak rate test program which was developed utilizing the then recently-approved test program for Hatch 2.
In its review of this March 5,1979 submittal, the staff determined that an exemption to the requirement of 10 CFR 50, Appendix J is required for the proposed testing of the main steam isolation valves (MSIVs) so that they may be tested at 1/2 the Appendix J required pressure and so that the leakage through the MSIV's is not required to be added in'the summation of the leakage from the other isolation valves and penetrations.
Environmental Impact of the Proposed Action:
The proposed exemption to the Appendix J test requirements'for the MSIV's will not cause post-accident radiological releases to exceed those determined previously for Hatch 1.
The proposed exemption does not otherwise affect facility radiological effluents, or any significant occupational exposures.
Likewise, the proposed exemption does not affect facility nonradiological effluents and has no other
. 7590-01 environmental impact.
Therefore, the Commission concludes there are no measurable radiological or nonradiological environmental impacts associated with the proposed exemption.
Since the Commission has concluded there is no measurable environmental impact associated with the proposed exemption, any alternatives either will have no environmental impact or will have a greater environmental impact.
The principal alternative to the exemption would be to require literal compliance with Appendix J to 10 CFR Part 50.
Such an action would not enhance the protection of the environment.
Alternative Use of Resources:
This action does not involve the use of resources not considered previously in connection with the Final Environmental Statement (FES) relating to this facility, FES for Edwin I. Hatch Units 1 and 2, USAEC (October 1972).
Agencies and Persons Consulted:
The Commission's staff reviewed GPC's request and did not consult other agencies or persons.
FINDING OF NO SIGNIFICANT IMPACT The Commission has determined not to prepare an environmental impact statement for the proposed exemption.
Based upon the environmental assessment, we conclude that the proposed action will not have a significant effect on the quality of the human environment.
. 7590-01 For further details with respect to this action, see the request for exemption dated March 5, 1979, which is available for public inspection at the commission's Public Document Room, 1717 H Street, N.W., Washington, D.C., and at the Appling County Public Library, 301 City Hall Drive, Baxley, Georgia.
Uated at Bethesda, Maryland, this 7th day of October 1986.
