UNITED STATES NUCLEAR REGULATORY COMMISSION ADVISORY COMMITTEE ON REACTOR SAFEGUARDS WASHINGTON, D. C. 20555 October 18, 1983 Mr. William J. Dircks Executive Director for Operations U. S. Nuclear Regulatory Commission Washington, DC 20555
Dear Mr. Dircks:
SUBJECT:
SEVERE ACCIDENT DECISIONS FOR EXISTING NUCLEAR POWER PLANTS During its 282nd meeting, October 13-15, 1983, the ACRS met with members of the NRC Staff to continue discussion of a draft document dealing with severe accident policy development entitled, "Severe Accident Decisions for Existing Nuclear Power Plants."
This report was also discussed with members of the NRC Staff during a Subcommittee meeting on October 12, 1983.
We consider the current draft to represent an improvement over the one on which we commented in our \
September 2, 1983 letter to Chairman Palladino.
We endorse the current proposal to blend deterministic and probabilistic ap-proaches in order to construct an appropriate regulatory framework.
The Committee also recommends that a similar approach be used for future plants.
The general approach seems reasonable.
We expect to study and comment further on the relationships being established among regulatory questions, policy issues, technical questions, and the research needed to provide information not currently available.
We observe that the Severe Accident Research Program was planned before this proposed approach was developed.
We recommend that those managing and performing the research be asked to ensure that such research will contribute importantly to answering the regulatory questions.
We plan to continue our review of this activity.
Sincerely,
~CB J. J. Ray 9-Chairman 1977
