UNITED STATES NUCLEAR REGULATORY COMMISSION ADVISORY COMMITTEE ON REACTOR SAFEGUARDS WASHINGTON, D. C. 20555 May 9, 1978 Mr. Lee V. Gossick Executive Director for Operations U. S. Nuclear Regulatory Cornnission Washington, DC 20555
SUBJECT:
LIQUID PATHWAY GENERIC STUDY
Dear Mr. Gossick:
During its 216th and 217th meetings, April 6 and 7, and May 4 and 5, 1978, the Advisory Conmittee on Reactor Safeguards reviewed the Liquid Pathway Generic Study (NUREG-0440), which discusses the irrpacts of ac-cidental radioactive releases to the hydrosphere from floating and land-based nuclear pov1er plants. NUREG-0440 was also considered during a Subcornnittee meeting in Washington, DC on March 22, 1978. This matter and an earlier draft version of this report have been the subject of ongoing review by the Committee since 1975. During its review, the Conmittee had the benefit of presentations by representatives of the NRC Staff and Offshore PCMer Systems (OPS).
Although the discussions at these meetings indicated that there are still areas of disagreement between the NRC Staff and OPS on specific details of the various assurrptions entering the calculations, it appears that a reasonable perspective has been developed on the range of poten-tial accidents, the identity and sources of the critical radionuclides, and the acconpanying dose patterns and consequences. The current study also appears to provide a basis for evaluating possible design nodifi-cations. Although the Cornnittee recorrmends that the NRC Staff and OPS continue to work to resolve disagreements and to eliminate weaknesses in these assessments, the ACRS believes that the perspective provided by the study can serve as a useful basis for current evaluations of the health and safety risks of radionuclide releases to the hydrosphere from land-based and proposed floating nuclear pov1er plants.
Sincerely yours,
~~
Chairman 604
