SUBJECT:
SUMMARY
OF MEETING WITH SANDIA LABORATORIES ON SYSTEMS INTERACTION Members of the NRC staff met with representatives of Sandia Laboratories on January 8,1980 in Bethesda, Maryland to discuss the draft Final ',eport prepared by Sandia Laboratories on Phase I of the Generic Task No. A-17, Systems Interaction in Nuclear Power Plants.
A list of persons who attended the meeting is enclosed with this summary report.
The significant items discussed at this meeting are summarized in the following paragraphs.
Dr. Hanauer, Director of Unresolved Safety Issues Program, presented the overall objectives of the NRC staff review of the Phase I tr,chnical assistance on systems interaction that is included in the draft Final Report by Sandia Laboratories.
There are two main objectives of the NP,C staff review.
The first objective of the NRC staff review is to provide Sandia Laboratories with guidance on revising the draft Fi.',al Report.
The kind of guidance that we intend to provide is in the nature of making the report clearer, for example, and to correct any technical inaccuracies obviously.
Dr. Hanauer stated that we will not censure the work of Sandia Laboratories.
This first objective review will be accomplished mostly by the task members of the Unresolved Safety Issues (USI) Program staff.
Of course, we welcome any comments from other members of the NRC staff.
The USI review staff consists of D. Fischer, J. Zwolinski, M. Srinivasan, T. Scarbrough, and J. Angelo. Our goal is to complete this part of the review and inform Sandia Laboratories of our findings by February 1,1980.
The second objective of the NRC ctaff review is to take the results and conclusions made by Sandia Laboratories in the draft Final Report and make a determination on implementing the findings for operating reactors, reactors under construction, and reactors currently in the licensing review process.
The NRC findings will be issued in a NUREG Report which will contain the proposed requirements and safety evaluation.
This NUREG will be issued for peer, public and ACRS review.
The proposed date for issuance of the NUREG is April 15, 1980.

JAN 141980 This second review objective whose goal is the issuance of a NUREG Report is now scheduled for April 15, 1980.
The NRC staff members who are expected to participate in this review effort, including technical input to the proposed requirements and safety evaluation, should have been designated by the NRR Division Directors involved (DSS and 00R).
Jack Hickman of Sandia Laboratories presented a brief overview of the scope and objectives of the technical assistance effort by Sandia Laboratories on systems interaction. Mr. Hickman explained that one of the principal objectives was to develop a method of examining a nuclear plant design for interaction potentials that would have broad application.
The second objective was to apply this method in a rather severely restricted way to search for interactions in a narrow range of interactions, and then to assess the Standard Review Plan to determine whether the plan addressed these interaction potentials.
Following this brief management overview of the program, W. Cramond and G. Boyd of Sandia Laboratories presented detailed information on the development of the fault trees and on the use of the Set Equation Transformation System (SETS) computer code to evaluate the fault trees for the commonalities which identify systems interaction potentials.
Basically, there are three independent fault trees:
one tree for each of the three safety functions which were considered as top events that could lead to the single top event defined as " unacceptable core damage."
