Dear Sir:

Subject:

~ Docket Nos. 50-361 and 50-362 San Onofre Nuclear Generating Station Units 2 and 3 As requested, this letter provides our response for San Onofre Units 2 and 3 to IE Bulletin No. 83 08: " Electrical Circuit Breakers with an Undervoltage Trip feature in Use in Safety-Related Applications Other than the Reactor Trip System."

Safety-Related systems at San Onofre Units 2 and 3 have been reviewed, and it has been determined that a circuit breaker with an undervoltage trip' attachment is not being used in a saftey-related application other than as a reactor trip breaker. Therefore, IE Bulletin 83-08 is not applicable-to San Onofre Units 2 and 3 and no further action related to this bulletin will be taken.

Subscribed on this 7Eb' day of Mm'Z) ,1984.
