Dear Mr. Keppler:
The purpose of this transmittal is to update information provided in Reference (a) relative to the HFA relay assembly cracking replacement program.
General Electric (NSSS-San Jose) has completed the replace-ment of lexan coils on all of the safety-related NSSS HFA relays for Units 1 and 2 with the exception of some Unit 2 relays that were damaged during construction.
The remaining Unit 2 NSSS safety related relays will be replaced with new qualified relays.
General Electric (IS&E), contracted by Commonwealth Edison Company, has completed the replacement of lexan coils on all of the safety-related balance-o f-plant HF A relays for Units 1 and 2, with the exception of four relays that were not upgraded due to a lack of l
qualified replacements.
Reference (b) recommended that a periodic visual inspection program be established and maintained until such time as the relays are upgraded or replaced.
Such a program will be l
implemented by LaSalle County Station by February 1,1983.
