Dear Sir:

SUBJECT:

FORKED RIVER NUCLEAR GENERATING STATION DOCKET NO. 50-363 RESPONSE TO IE BULLETIN 79-28 In response to the action requested in the IE Bulletin No. 79-28 regarding the replacement of top cover gaskets on stem mounted limit switches, Model EA 180 with a date code between 02-79 through 08-79, manufactured by NAMCO Controls, we wish to advise you of the following:

1. NAMCO EA 180 switches have not been installed in any safety related equipment located inside or outside containment, as far as the Forked River Facility is concerned.
2. The electrical equipment assigned to the Forked River Facility is in the process of being purchased or to be delivered at a later date. Therefore, our action of examining and identifying the four digit number on the switches cannot be taken at this time.
3. The plans and programs, including schedules for corrective action, cannot be proposed without proper findings. However, as a pre-cautionary measure, the equipment specification for valve assemblies used in safety related circuits shall include a requirement for the vendor receiving the equipment award to certify by test, design review, and/or analysis that the stem mounted limit switches to be installed for valve operation is qualified to perform its intended function under accident conditions.

Very truly yours, Udt! . .M' Ivan R. Finfro ,J.
