UNITED STATES NUCLEAR REGULATORY COMMISSION ADVISORY COMMITTEE ON REACTOR SAFEGUARDS WASHINGTON, D. C. 20555 July 13, 1982 Honorable Nunzio J. Palladino Chairman U. S. Nuclear Regulatory Commission Washington, DC 20555
Dear Dr. Palladino:
SUBJECT:
ACRS REPORT ON THE PERRY NUCLEAR POWER PLANT, UNIT 1 During its 267th meeting, July 8-10, 1982, the Advisory Committee on Reactor Safeguards reviewed the application of the Cleveland Electric Illuminating Company (Applicant), acting on behalf of itself and as agent for Duquesne Light Company, Ohio Edison Company, Pennsylvania Power Company, and the Toledo Edi son Company, for a 1 icense to operate the Perry Nuclear Power Plant, Units 1 and 2.
The plant is to be operated by the Cleveland Electric Illuminating Company.
A tour of the facilities was made by members of the Subcommittee on the morning of June 28, 1982, and a Subcommittee meeting was held in Cleveland, Ohio on June 28 and 29, 1982 to consider the application.
During its review the Committee had the benefit of discussion with represen-tatives of the Applicant, the NRC Staff, and members of the public.
The Committee al so had the benefit of the documents 1 isted.
The Committee commented on the application for a permit to construct this plant in its reports dated December 12, 1974 and May 12, 1975.
The Perry Nuclear Power Plant is located in Lake County, Ohio near Lake Erie approximately 35 miles northeast of Cleveland, Ohio and 21 miles southwest of Ashtabula, Ohio.
Units 1 and 2 use General Electric BWR-6 nuclear steam supply systems with a rated power of 3579 MWt and a Mark III pressure suppression containment system with a design pressure of 15 psig. Construc-tion of Unit 1 is about 83% complete and Unit 2 is about 43% complete.
Because loading of fuel for Unit 2 is scheduled for May 1987, the Committee does not believe it appropriate to report at this time on the operation of Unit 2.
Our review included the management organization, technical support staff, status of operational staffing, and the training program.
This is the first nuclear power plant to be operated by the Applicant.
The plant staff has a minimum amount of boiling water reactor (BWR) nuclear background.
We agree with the NRC Staff on the urgent need for additional personnel with BWR experience within the operating management.
The Applicant should fill the position of Superintendent of Plant Operations in the near future.
Experi-enced senior technical support personnel should be included in the staffing plans of the Applicant.
This matter should be resolved in a manner satis-factory to the NRC Staff.
We wish to be kept informed.

Honorable Nunzio July 13, 1982 As a result of adverse experience on the Perry project several years ago, the Applicant restructured its quality assurance procedures and its quality control and assurance organization.
The revised organization has been reviewed and audited by the NRC Staff.
We wish to receive a report from the NRC Staff which discusses design and construction problems, their disposi-tion, and the overall effectiveness of the effort to assure appropriate quality.
The Applicant has committed several technical staff members to matters related to probabilistic analysis and studies of systems interactions.
We believe that efforts of this sort by the operating utilities are to be encouraged.
The Mark III suppression pool dynamic loads have been identified as an Out-standing Issue in the NRC Staff's review.
The NRC Staff has provided the Applicant with a proposal for the appropriate design basis loads, and it appears that the Perry design wi 11 be able to accommodate these loads.
Additional concerns with the design of the Mark III containment have been recently brought to our attention.
The NRC Staff is currently assessing these issues for impact on the Mark III design.
We will continue to discuss with the NRC Staff, on a generic basis, Mark III suppression pool dynamic loads and other additional Mark III issues.
Hydrogen control systems for Mark III containments are being developed by the Mark III Owners Group.
Efforts by this Owners Group are being directed toward the development of a hydrogen ignition system which makes use of distributed ignition sources.
The NRC Staff has indicated that they will be able to meet with the Committee on this matter in the near future.
We expect to review this system on a generic basis.
Acceptability of this system is designated as a License Condition.
We recommend that the Applicant and the NRC Staff conduct studies to evalu-ate the margins available to accomplish safe shutdown, including long-term heat removal, following an earthquake of somewhat greater severity and lower likelihood than the safe shutdown earthquake.
We believe it is important that there should be considerable assurance that the combination of seismic design basis and margins in the seismic design is such that this accident source represents an acceptably low contribution to the overall risk from this plant.
We recommend that any needed modifications be made before the plant resumes operation following the second refueling.
We wish to be kept informed on the progress and results of these studies.

Honorable Nunzio July 13, 1982 During our review, the NRC Staff identified a number of other License Conditions, Confirmatory Matters, and Outstanding Issues which remain to be resolved.
Except for the issue of turbine missiles, we are satisfied with the progress on these topics, and we believe that they should be resolved in a manner satisfactory to the NRC Staff.
We wish to be kept informed con-cerning resolution of the turbine missile issue, and wish to receive a technical report which discusses and evaluates the problems involved.
If due consideration is given to the recommendations above, and subject to satisfactory completion of construction, staffing, and preoperational testing, the ACRS believes there is reasonable assurance that the Perry Nuclear Power Pl ant, Unit l can be operated at power levels up to 3579 MWt without undue risk to the health and safety of the public.
