Dear Mr. Collins:

g River Bend Station Unit 1 Docket No. 50-458 Final Report /DR-120 On May 27, 1983, Gulf States Utilities Company (GSU) notified Region IV of a condition potentially reportable under 10CFR50.55(e) concerning the improper storage and subsequent deterioration of four standby switchgear circuit breakers (DR-120). GSU subsequently issued an Interim Report dated June 27, 1983.

Investigation revealed the improper storage of circuit breakers was limited in scope and that the internal devices of the circuit breakers required for proper ACB operation had not been affected. GSU concludes that had this condition remained uncorrected, it could not have adversely affected the safe operations of the plant and is therefore not reportable under 10CFR50.55(e). This completes GSU's response on this subject.

Sincerely, r

[J.E.Bo er i
