Ifthe micro is not operating, and theradiation level increased above the alarm trip point, the relay contact outputs used to initiateESFAS action, would not have changed state as required. To confirm the condition, a testinput signal, that exceeded the alarin trip point, was injected into the Local Radiation Processor

(LRP). The alarm relay at the LRP changed state, but the relay output at the RDU did not,i'ndicating,that an unidentified fail condition exists in the design. Further information isavailable'in'PG&E's Fax. dated 1/24/97.
