Subject:  Interim 10CFR21 Report 21-97-059: Refurbished Circuit Breakers

          Returned From Nuclear Logistics Incorporated with Various

          Discrepancies



Dear Madam or Sir:



     On December 19, 1997, a Condition Report was initiated to

investigate several discrepancies found during receipt inspection of

three safety-related Westinghouse DHP circuit breakers.  These circuit

breakers had been sent to Nuclear Logistics Incorporated (NLI) for

refurbishment.  Examples of discrepancies include: Loose nut on puffer

diaphragm, trip latch clearance out of specification, main contact

clearance out of specification, and main contact separation out of

specification.  Illinois Power initially decided to attempt to resolve

these discrepancies under the Maintenance Work Request Program.  However,

once work had started, Illinois Power personnel determined that the

discrepancies were more complicated than originally thought and

discontinued work on investigating and correcting the discrepancies.  The

circuit breakers were subsequently returned to NLI to resolve the

identified discrepancies.  NLI is also assisting with the determination

of the impact of the identified discrepancies and the reportability

determination under 10CFR21.



     Illinois Power is still evaluating these conditions under 10CFR21

and has not yet determined if the identified discrepancies are

reportable.  Illinois Power will complete the evaluation of this issue by

April 15, 1998.



     Additional information about this issue may be obtained by

contacting F. D. Chenoweth, Nuclear Station Engineering Department, (217)

935-8881 extension 3658.





                         Sincerely yours,



                         Walter G. MacFarland, IV

                         Chief Nuclear Officer
