Attachment I Response to Request for Additional Information Regarding Revisions to Loss-of-Power Diesel Generator Start Instrumentation Limiting Safety System Settings and Diesel Generator Load Test Value is initiated with subsequent closing of the diesel generator supply breaker(s) to the bus(es) that experienced the UV. Component cooling water pumps are tripped if a safety injection signal is present and safeguards loads are sequenced on.
When being fed from the onsite diesel generators, actuation of the bus UV system strips all bus loads, except containment spray, MCC C and D and required downstream MCCs and component cooing water breakers on buses 14 and 16. The diesel generator supply breakers to its respective safeguards buses are not tripped. If a safety injection signal is present then safeguards loads will be re-sequenced onto their respective bus once voltage recovers above the UV relay reset values, component cooling water pumps will not be in-service. If a safety injection signal is not present then loads are started upon bus voltage recovery, as required.
