UNITED STATES NUCLEAR REGULATORY COMMISSION ADVISORY COMMITTEE ON REACTOR SAFEGUARDS WASHINGTON, D. C. 20555 October 19, 1981 Honorable Nunzio J. Palladino Chainnan U.S. Nuclear Regulatory Commission Washington, DC 20555
SUBJECT:
REPORT ON THE SHOREHAM NUCLEAR POWER STATION UNIT 1
Dear Dr. Palladino:
During its 258th meeting. October 15-17 1 1981 1 the Advisory Committee on Reactor Safeguards completed its review of the application of the Long Island Lighting Company (LILCO) for a license to operate the Shoreham Nuclear Power Station Unit 1. A Subcommittee meeting was held in Washington. D.C. on Sept-ember 30 1 1981 to consider this project. A tour of the facility was made by members of the Subcommittee on April 30 1 1981. During its review, the Com-mittee had the benefit of discussions with representatives of the Applicant and the NRC Staff. The Committee also had the benefit of the documents listed. The Committee reported on the construction pennit application for this plant in a letter to AEC Chainnan Glenn T. Seaborg dated December 18 1 1969.
The Shoreham plant is located on Long Island in the Town of Brookhaven, Suffolk County. New York, about 55 miles east-northeast of downtown New York City. It uses a GE BWR-4 nuclear steam supply system with a rated power level of 2436 MWt and a Mark II pressure suppression containment with a de-sign pressure of 48 psig. The Shoreham plant is one of three included in the Mark II Owners Group lead plant program. The NRC Staff has completed its review of the lead plant program and has issued NUREG-0487 and Supple-ments I and II, "Mark II Containment Lead Plant Program Load Evaluation and Acceptance Criteria." The NRC Staff has concluded that Shoreham satisfies these criteria. In addition. LILCO has committed to evaluate the final ge-neric load definition of NUREG-0808 1 "Mark II Containment Program Load Eval-uation and Acceptance Criteria," against the load specification used in the interim evaluation (NUREG-0487). Subject to satisfactory completion of this work, the NRC Staff has found the Shoreham containment acceptable.
We concur in this finding.
LILCO described the management organization and the technical personnel available for operation of the Shoreham plant. Because of LILCO's lack of BWR operating experience, the NRC Staff is requiring that the control room staff and senior plant management be provided with advisors who have sub-stantial BWR operating experience.
We concur with the NRC Staff that sup-plemental personnel experienced in BWR operation are needed until adequate operating experience is developed by the LILCO staff.

Dr. Nunzio October 19, 1981 LILCO described three safety review committees which will be a pennanent part of the Shoreham organization.
We believe that these committees should include some expertise from sources outside LILCO's or its contractors' or-ganizations to provide balanced professional judgment on matters that could affect public health and safety.
LILCO should organize the planned safety review committees as soon as practical so they will have time to develop an understanding of plant related safety matters prior to plant operation.
LILCO also described its program and philosophy for training of personnel.
The initial training that the operations staff has received using a contractor-run training organization appears adequate.
However, LILCO should establish an in-house training program to be maintained on a continuing basis so that operational skills are enhanced.
LILCO has initiated a Shoreham plant assessment based on probabilistic risk assessment techniques.
The Applicant's assessment effort in this area will provide a valuable addition to his operational knowledge.
An outstanding issue in the NRC Staff's Safety Evaluation Report dated April 1981 and Supplement 1 to that report dated September 9, 1981 involves the re-mote shutdown system.
The NRC Staff is concerned that a single, random fail-ure in the instruments and controls of systems controlled from the remote panel or in the systems themselves may prevent the remote shutdown panel from per-fonning its function. This item should be resolved in a manner satisfactory to the NRC Staff. The Committee wishes to be kept informed.
The NRC Staff has identified other outstanding issues in its Safety Evaluation Report.
We believe that these outstanding issues can be resolved and recom-mend that this be done in a manner satisfactory to the NRC Staff before op-eration at full power.
We believe that if due consideration is given to the recommendations above, and subject to satisfactory completion of construction, staffing, and pre-operational testing, there is reasonable assurance that Shoreham Nuclear Power Station Unit 1 can be operated at power levels up to 2436 MWt without undue risk to the health and safety of the public.
Sincerely,
~~Ma~
Chafnnan
