UNITED STATES NUCLEAR REGULATORY COMMISSION ADVISORY COMMITTEE ON REACTOR SAFEGUARDS WASHINGTON, D. C. 20555 Honorable Nunzio J. Palladino Chairman U.S. Nuclear Regulatory Commission Washington, D. C.
20555
Dear Dr. Palladino:
October 13, 1982
Subject:
ACRS REPORT ON WASHINGTON PUBLIC POWER SUPPLY SYSTEM NUCLEAR PROJECT NO. 2 During its 270th meeting, October 7-8, 1982, the ACRS completed its review of the application of the Washington Public Power Supply System (WPPSS) (Ap-plicant) for a license to operate th.e WPPSS. Nuclear Project No. 2 (WNP-2).
A Subcommittee meeting was held in Richland, Washington on September 2-3, 1982 to consider this project.
A tour of the facility was made ~Y members of the Subcommittee on September 2, 1982.
During its review, the Committee 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 permit application for this pl ant (then designated as Hanford No. 2 Nuclear Power Plant} in a report to AEC Chairman James R. Schlesinger, dated October 19, 1972.
WNP-2 is located in the southeastern area of the U.S. Department of Energy's Hanford site in Benton County, Washington.
WNP-2 uses a General Electric BWR/5 nuclear steam supply system with a rated power level of 3323 MWt and has a Mark II pressure suppression containment system with a design pressure of 45 psig.
Fuel loading is scheduled to begin during September 1983.
WPPSS is a municipal corporation and a joint operating agency of the state of Washington.
WNP-2 is the first WPPSS unit (of an originally planned five units} to be considered for an operating license.
A work stoppage was initiated in June 1980, in order to assess QA/QC problems.
WPPSS has since brought in more experienced management that has resulted in substantial improvement in the Licensee's project management teams and management controls, and in the attitude of the project personnel toward quality.
Presently, at WNP-2 there is an ongoing reverification program involving sampling, inspection, and documentation review.
The NRC will continue to monitor progress of this program.
The Committee wishes to be kept infonned.
The NRC Staff and the Applicant are in the process of determining the proper criteria and verification procedures for electrical isolation and for identification of Class lE and associated circuits.
This matter should be resolved in a manner satisfactory to the NRC Staff. The Com~ittee wishes to be kept informed.

Honorable Nunzio October 13, 1982 The WNP-2 design uses multiplexing in the service water control system.
This is the first plant we have reviewed that uses this type of service water control.
Because of the importance of this system to safety, we recommend that the NRC Staff confirm that service water needed for shutdown decay heat removal can be made available even if the multiplexing system malfunctions.
The Committee wishes to be kept infonned regarding this matter.
The NRC Staff has identified a number of Unresolved Safety Issues as being applicable to WNP-2.
There are also a number of Outstanding Issues, Con-firmatory Issues, and License Conditions.
We believe that these matters can be resolved in an acceptable manner.
The ACRS believes that if due consideration is given to the matters noted and to our recommendations above, and subject to satisfactory completion of construction, staffing, and pr.eoperational testing, there is reasonable assurance that WNP-2 can be operated at power 1 evel s up to 332_3 MWt without undue risk to the health and safety of the public.
