Final 10CFR50.55(e) Report: Brown Boveri K-Line Circui t Breaker with Overcurrent Trip Device Model OD-4 or OD-5 (CDR 85-00-11)

Dear Sir:

In References (b) and (c), we reported a 10CFR50.55(e) deficiency regarding Brown Boveri K-Line circuit breakers with overcurrent trip devices Model OD-4 or OD-5. Incorrect short time delay band levers (links) were supplied in these trip devices. The incorrect levers may limit the travel of the short-time armature and cause the short-time element to be inoperative in the maximum band. This could inhibit a safety-related circuit breaker from performing its intended safety func-tion.

The corrective action, as specified in Reference (c) (i.e., replace-ment of the incorrect levers), has been completed for Unit 1. As such, this is considered our final report on this item for Unit 1.
