UNITED STATES NUCLEAR REGULATORY COMMISSION ADVISORY COMMITTEE ON REACTOR SAFEGUARDS WASHINGTON, D. C. 20555 Honorable Nunzio J. Palladino Chainnan
- u. s. Nuclear Regulatory Co11111ission Washington, DC 20555
Dear Dr. Palladino:
September 10, 1984
SUBJECT:
ACRS REPORT ON THE MILLSTONE NUCLEAR POWER STATION UNIT NO. 3 During its 293rd meeting, September 6-8, 1984, the Advisory Corm1i ttee on Reactor Safeguards reviewed the application of the Northeast Nuclear Energy Company (the Applicant) for a license to operate the Millstone Nuclear Power Station Unit No. 3.
This application was considered by the ACRS Subcommittee on the Millstone Nuclear Power Station Unit No. 3 and the Subcommittee on Reliability and Probabi1istic Assessment at a combfoed meeting held on August 28 and 29, 1984 at Windsor Locks, Connecticut.
Members and consultants of these Subcommittees toured the facility on August 28, 1984.
During our review, we had the benefit of discussions with representatives and consultants of the Applicant, Westinghouse Electric Corporation, Stone & Webster Engineering Corporation, and the NRC Staff.
We also had the benefit of the documents referenced.
The ACRS corm1ented on the construction permit application for the Millstone Nuclear Power Station Unit No. 3 in a report dated April 16, 1974.
The Millstone Nuclear Power Station Unit No. 3 is located on Long Island Sound, on the east side of Niantic Bay, in Waterford, Connecticut.
Mill-stone Unit No. 3 uses a four-loop pressurized water reactor, with a rated thermal power level of 3411 MW, supplied by the Westinghouse Electric Corporation.
It is similar to that of the Comanche Peak Steam Electrk Station.
The containment for the plant, similar to that of the Surry Power Station Units 1 and 2, is a subatmospheric design, incorporating a steel-1 foed reinforced concrete structure and a supplementary 1 eak col lec-tion and release system.
The Millstone Nuclear Power Station Units 1 and 2, presently in operation, are located on the same site. Unit 1 uses a boiling water reactor, with a rated thermal power level of 2011 MW, and Unit 2 uses a Cont>ustion Engineer-ing pressurized water reactor-, with a rated thermal power level of 2700 MW.
Our review included an evaluation of the management organization, the opera-tional staff, and the training program for the operating and maintenance staff. The tour of the plant included the training center located on the Millstone site.
A plant-specific simulator for Millstone Unit No. 3 is expected to be installed and in operation well before startup.

Honorable Nunzio September 10, 1984 During our discussions, the Applicant demonstrated an extensive knowledge of the operation, design, and construction features of the plant.
We conclude that the Applicant is well qualified to operate Millstone Unit No. 3.
During our meeting, the NRC Staff identified a number of open issues that must be resolved prior to the granting of an operating license.
We believe that these can be resolved in a manner sati sfactor:y to the NRC Staff.
We wish to be kept informed.
In response to a request from the NRC Staff, the Applicant submitted a Probabilistic Safety Study (PSS) in August 1983.
The PSS is now being reviewed by the NRC Staff.
In our meeting with the Applicant, a number of plant features were identified that have been modified as a result of the PSS.
The NRC Staff is continuing its review of the PSS with special atten-tion being given to resistance to seismic events.
At this time, we are not prepared to comment on the suitability of the current NRC Staff confirmatory requirement concerning seismic capability.
We expect to continue our review of the PSS and to review the NRC Staff's analyses as they become available.
However, this review need not be completed before a decision is made on an operating license for this unit.
We believe that, subject to the resolution of open items identified by the NRC Staff and subject to the satisfactory completion of construction, staffing, and preoperational testing, there is reasonable assurance that the Millstone Nuclear Power Station Unit No. 3 can be operated at power levels up to 3411 MWt without undue risk to the health and safety of the public.
Sincerely,
~.~~
