Division of Systems Safety and Analysis

SUBJECT:

PUBLIC MEETING ON JANUARY 7, 1993 (flRE BARRIER ACCEPTANCE CRITERIA)

On January 7,1993, a public meeting was held with various industrial-representatives who have sold fire barrier-products to the commercial nuclear power industry.

A list of the meeting attendees is attached.

A copy of the meeting handouts is available through the public document room.

During the past 18 months, the NRC has been evaluating problems associated with Thermo-Lag fire barrier systems.

The NRC^has issued 5 informa' ion-notices, a bulletin, and supplement and a generic letter which' addresses lhermo-Lag.

i The purpose of the meeting was to discuss the applicability of the issues that have been identified to other fire barrier systems.

The staff stated that it is conducting a programatic review and has not completed its reassessment of i

other fire barrier systems.

It is our intent to address other fire barrier I

products through a generic letter supplement in the September 1993 time-frame.

The fire barrier representatives were interested in receiving assurances that their products continue to be acceptable.

The staff stated that we cannot draw that conclusion until our review is completed. However, if the staff had information that other fire barrier products had failure mechanisms similar to Thermo-Lag, we would have issued similar generic communications.,

If industry has specific product information that address the issues identified through our generic communications, they should submit it to aid in resolution of the issues.

l Additional discussions focused on the regulatory process for the proposed staff acceptance criteria for fire barrier assemblies used _to separate safe shutdown functions. The staff stated that it plans to follow the normal-generic review process for implementation of the proposed criteria, ggut mn-d by Conrad E. McCracken, Chief 9302010202 930114 Plant Systems Branch PDR ORO NRRB Division of Systems Safety and Analysis PDR
