Supplement 1, dated 1
August 3, 1989 l
Reference 1 required licensees to identify and trace to the circuit breaker manufacturer (CBM),.all i
molded-case circuit breakers (MCCBs) stored for use in C
safety-related applications.
Union Electric provided the results of this review to the NRC as Reference 2.
Based on a preliminary review of responses to Bulletin 88-10, the MRO staff issued Referenco 3 which requested licensees to:
1.
Review written reports submitted to the NRC i
in accordance with Bulletin 88-10 and verify that the, responses meet the hulletin l
provisions as clarified by the bulletin supplement, and; 2.
Prepare and retain documentation for possible audit that indicates that the l
review has been performed as requested.
Union Electric has reviewed the Bulletin 88-10 response (Reference 2) against the clarifications a
contained in the bulletin supplement.
As a result the review of breaker traceability was expanded to include original spares purchased under the construction program which were received after August 1, 1983.
