UNITED STATES NUCLEAR REGULATORY COMMISSION ADVISORY COMMITTEE ON REACTOR SAFEGUARDS WASHINGTON, D. C. 20555 October 20, 1981 Honorable Nunzfo J. Palladino Chainnan U.S. Nuclear Regulatory Commission Washington, DC 20555
SUBJECT:
INTERIM REPORT ON GRAND GULF NUCLEAR STATION UNIT 1
Dear Dr. Palladino:
During fts 258th meeting, October 15-17, 1981, the Advisory Committee on Reactor Safeguards reviewed the application of the Mfssfssfppf Power and Light Company (MP&L), Middle South Energy, Inc., and the South Mississippi Electric Power Association for a license to operate the Grand Gulf Nuclear Station Units 1 and 2.
The units are to be operated by the Mississippi Power and Light Company.
A Subcommittee meeting was held fn Jackson, Mississippi on September 17-18, 1981 to consider this project. A tour of the facility was made by members of the Subcommittee on September 17, 1981. During its review, the Committee had the benefit of discussions with representatives of the Applicant, the NRC Staff, and members of the public.
The Committee also had the benefit of the documents listed. The Committee commented on the construction pennit application for this station fn its report dated May 15, 1974.
The Grand Gulf Station is located fn Claiborne County, Missfssfppf on the east side of the Mississippi River about 25 miles south of Vicksburg, the nearest city having a population fn excess of 25,000 persons.
Each Grand Gulf unit fs equipped with a General Electric BWR-6 nuclear steam supply system with a rated power level of 3833 MWt and a Mark III pressure suppression containment system with a design pressure of 15 psfg.
Construction of Unit 1 fs over 90% complete while Unit 2 is about 20% com-plete and construction of ft has been temporarily suspended.
Because of the extended schedule for Unit 2, the Committee does not believe ft appropriate to report on operation of Unit 2 at this time.
The Committee review included the management organization, capability, and operator training of MP&L.
This fs the first nuclear power plant to be operated by this utility. While the plant staff has a reasonable amount of 678
Honorable Nunzio October 20, 1981 nuclear background, the ACRS agrees with the NRC Staff on the need for ad-ditional personnel with BWR experience, at least during the first year or two of operation.
MP&L also needs to fill certain senior technical person-nel positions in its management organization. The Committee rec011111ends that the MP&L Nuclear Safety Review Board include two or more experienced voting members from outside MP&L having appropriate backgrounds.
During this meeting, the NRC Staff identified a large number of license conditions and confirmatory matters, and several outstanding issues which remain to be resolved. Except for the two issues identified below, the ACRS is satisfied with progress on the other topics and believes that they should be resolved in a manner satisfactory to the NRC Staff.
We have not completed our review of the following outstanding issues identi-fied in the NRC Staff Safety Evaluation Report:
. dynamic loads on structures above the Mark III suppression pool due to froth impact
. hydrogen control The ACRS will complete its review of the full power operating license when the Staff and the Applicant have made sufficient additional progress in resolving these items.
In the interim, the ACRS believes that if due consideration is given to the recommendations above, and subject to satis-factory completion of construction, staffing, and preoperational testing, it would be acceptable for Grand Gulf Nuclear Station Unit 1 to be operated at power levels up to 5% of full power.
