Dear Mr. Arlotto:

Subjecc:

INTERNAL SEALING OF CONDUITS THROUGH FIRE BARRIERS In response to the differing guidance in BTP 9.5-1 Appendix A, NUREG 0800 and 10 CFR 50.48 Appendix R,

and in che interest of providing cost-effective fire proteccion based on sound technical information, a group of 23 nuc lear utilities has embarked on a

research project to evaluate internal conduit seal

..g requirements and develop design guidelines based on fire test data.

This project is being coordinated by Visconsin Electric Power Comp -ny wich the technical assistance of Professional i;oss Concrol, inc.

The project consists of the following tasks:

1.

Collect and evaluate exis-ing fire test data on internal conduit sealing.

2..Survey existing plant configurations of conduit penecracions.

Develop and concIucc a test program to provide acldirinnal data.

4.

Develop generic guidance for internal sealing of conduits.

This proj ecc is scheduled for completion by the end of 1986 calendar year.

Because of this effort, che participating companies may delay final policy decisions on internal conduit sealing until this more complete technical basis is available.

'Me will keep the NRC informed and would welcome the opportunity to present the results of the project to you.
