SUBJECT:
GENERIC SAFETY ISSUE 191: 1999-04-14 MEETING
SUMMARY
A public meeting was held at the Department of Energy's Energy Training Complex in Albuquerque, New Mexico on August 18th and 19th to discuss the NRC-sponsored debris transport test program and possible industry involvement in the NRC-sponsored debris transport test program.
The debris transport test program is part of the generic safety issue (GSI) 191 study. The purpose of the GSI 191 study is to determine whether debris accumulation in containment following a postulated loss-of-coolant accident will prevent or impeded the performance of the emergency core cooling system. The meeting was requested by representatives of Nuclear Energy Institute (NEI) and the three pressurized water reactors owners groups (PWROGs).
Besides representatives from NRC, NEl, and PWROGs, representatives from various vendors and utilities (domestic and foreign) attended and participated in the meeting.
Copies of the original and amended meeting agenda are included in Attachment 1. A list of meeting attendees is included in Attachment 2. Presentations were given by Los Alamos National Laboratory (LANL) and the University of New Mexico (UNM) on the purpose of the test program, the design of the test facility, the application of test findings, and interpretation of survey' responses and their use.
Copies of the slides used during the meeting are available for distribution. A copy of the draft test plan has been placed in the NRC's public document room. The test program was developed jointly by the LANL and the UNM's Civil Engineering Department. The tests will be conducted at the UNM. Meeting attendees were given a tour of the test facility (see attached j
figure). A number of useful comments were provided by meeting attendees on the test I
program and the application of test results. Overallit appears that the response to NRC-
[
sponsored debris transport test program was favorable.
h FO NEl coordinated a survey sent to all PWR bcensees requesting infn.mation on containment and sump design. The response were submitted to the NRC on Ju. : 9,1999.

l Bes' ides discussing the technical merits of the NRC-sponsored debris transport test program, presentations were made or discussions were held regarding revision to GSI-191 study schedule, PWROGs involvement in the GSI-191 study, use of risk insights in GSI-191 study,
' and ongoing activities by Ontario' Power Generation.
Considerable time ' as spent explaining how NRC typically interact with stakeholders (and it w
merits repeating here):
(1)'
- all stakeholders should be given equal opportunity to participate (e.g.,
attendance at public meetings or comments on regulatory guidance).
(2)
NRC staff can make test data and analysis that do not form bases for regulatory position public (e.g., scaling analysis for test facility) because it is not considered predecisional.
(3)
NRC staff cannot make analysis that forms the bases for a regulatory position public prior to approval from NRC management.'
(4)
, NRC may make a regulatory position and the analysis that supports that position available for public comment prior to finalizing the position.
. NRC staff and NRC contractors can hold extensive, detailed technical or policy
-(5)
' discussions in a public forum, but should refrain from private conversations.
.(6)
NRC staff can hold private conversations with stakeholders (e.g., establishing agenda for a public meeting), so stakeholders should feel free to contact NRC L
staff., it is the responsibility of the NRC staff to avoid inappropriate conversations (e.g., discussing predecisional or proprietary matters).
Commitments l
The NRC staff made the following commitments during the meeting:
(1).
Stakeholders may be given the opportunity to witness tests, if visits can be accommodated with minimal interruptions to test schedule and burden on the people conducting the tests.
(2)
NRC staff committed to place the results (parametric tests only) from the NRC-sponsored debris transport tests in the NRC's public document room within two I
weeks of their generation.
(3)
NRC staff committed to place a technicalletter report, by LANL, documenting the work of the debris transport phenomena identification ranking table panel in the l
NRC's public document room, after it has been finalized and reviewed by the l --
NRC staff.
(4)-
The PWROGs have committed to draft a " status" letter that explicitly discusses to what extent they wish to participate in the GSI-191 study.
