Dear Dr. Palladino:
Subject:
TWO HUNDRED-SEVENTY-EIGHTH MEETING OF THE ADVISORY COMMITTEE ON REACTOR SAFEGUARDS, JUNE 9-11, 1983 278th ACRS Meeting The Committee met with representatives of the NRC Staff to discuss the proposed adoption of leak-before-break criterion in lieu of 'the double-ended pipe break for selected features of PWR plant design.
The Comittee met with representatives of the NRC Staff and completed its report to the NRC regarding the proposed NRC Safety Research Program Budget for FYs 1985 and 1986.
The Committee completed a report regarding General Electric Company's application for a final design approval of the GESSAR II (a GESSAR-238 nuclear island).
Copies of the reports and letters on the subjects noted above have been sent to you.
The Committee met with representatives of the NRC Staff to discuss proposed revisions to the GE SAFER /GESTR ECCS analysis methods for boiling water reactors.
The Committee met with representatives of the NRC Staff to discuss ACRS comments regarding proposed NRC priorities for resolution of generic items. ACRS comments regarding a portion of these items have been sent to the EDO.
Additional discussion of remaining items will be scheduled during the 279th ACRS meeting.
The Committee was briefed by the NRC Staff on SECY 82-1B, Proposed Commission Policy Statement on Severe Accidents and Related Views on Nuclear Reactor Regulation, and its implementation with regard to Final Design Approval of projects such as GESSAR-II.
The Committee was briefed by R. Mattson regarding information developed during the NRC Task Force review of the generic implications of the Salem Nuclear Station circuit breaker failure.
The Committee met with H. Denton, Director of NRR, and V. Stello, DEDR0GR, to discuss the status of and plans for SEP III, IREP, and NREP programs.
