HFA Relays in Use in Class 1E Safety Systems", dated March 12, 1984
Subject:
Replacement of General Electric HFA Relays Used in Class IE Safety Systems; IE Bulletin 84-02
Dear Sir:
In response to IE Bulletin No. 84-02, " Failure of General Electric Type HFA Relays in Use in Clase 1E Safety Systems", we have investigated the various applications of GE HFA relays a*. Seabrook Station.
CE HFA relays are used in both Class 1E Safety Systems and Non-Class 1E Systems. We have identified five HFA relays per unit at Seabrook Station that perform safety-related functions within a Class 1E Safety System. Other HFA relays identified are used in Non-Class 1E Systems or, if used in a Class 1E Safety System, do not perform a safety-relar.ed function. All HFA relays identified were manufactured prior to the availability of the Century Series relays with tefzel coil spools.
We plan to replace all HFA relays,used in Class 1E Safety Systems, which perform safety-related functions with Century Series HFA relays. The replacement of the relays will be completed prior to fuel load.
Since we plan to continue to use HFA relays with nylon or lexan type coil spools in non-safety-related applications, administrative controls dealing with maintenance, storage, and handling of spare relays and parts will be instituted to insure the segregation of safety-related and non-safety-related relays and parts.
