SUBJECT:
CONFlRMATORY ACTION LETTER
Dear Mr. Cook:
in Februa:
of this year, NRC inspectors identified deficiencias in Illinois Powor's (IP) maintenance program fcr safety related electrical circuit breakers. Following this finding, IP performed inspections and tosts in an offr:rt to establish reasonablo assuranco that safety related breakors will work when called upon. You reported the cornpletion of sufficient inspections and tests for the establishmont of such reasonablo assuranco during a public mooting on July 3,1997.
On July 22,1997, a saloty related Westinghouso 4160 volt,1200 amp breaker failed to open when cated upon in servico. This breaker had boon subjected to tho int.poctions and tests discussed above. _ On the same day, a non saloty related Westinghouse 4160 volt, 1200 amp breaker failed to close when called upon. As a result of the non-safoty related breaker failure, IP identified an ortor in the applicablo maintenanco proceduto which resulted in mis adjustment of a criticat intomal mechanism. During a public mooting on July 31 1997, IP informed the NRC that in addition to identifying this error, a method to identify the problem which led to the s.afety related breaker falluto of July 22 had boon found,' and that all necessary correctivo actions had boon taken for the other safoty related Westinghouse 4160 volt breakors. Durin0 this mooting,IP informed the NRC that'
- reasonable assuranco existed that safety related breakers would function when called upon.
' On August 5,'1997, another saloty related Westinghouse 4160 volt,1200 amp breaker
- failed to opon when called upon in mvico. This breaker had boon subjected to the inspections, tests, and correctivo actions discussed above.
