Docket No. 50-285
Dear Mr. Collins:
IE Bulletin 83-08; Electrical Circuit Breakers With an Undervoltage Trip Feature in Use in Safety-Related Applications Other Than the Reactor Trip System The Omaha Public Power District conducted a review of the subject bulletin.
The Port Calhoun Station does utilize GE AK-2 circuit breakers extensively throughout the 480 V distribution system.
However, examination of electrical schematics, wiring diagrams, and plant calibration procedures revealed that safety-related cir-cuit breakers are tripped by shunt devices only.
As such, they do not utilize the UV trip feature discussed in IE Bulletin 83-08.
Therefore, this letter hereby serves as a negative declaration, as required by the subject bulletin.
