8. We originally responded to this question thinking the tgRC was asking power source for startup logic. Power source for system and auxiliary systems in items gb are as follows:

All systems require offsite A.C. {115 kY) or onsi te A.C.

(dpean'] generator)except for:

HPCI (FNW +u~n) - requires offsite A,C. not loaded on diesels.

ADS - requires D.C.. power for operation of solenoids. =

SRV - requires no power source.

CS7: requires no power source.
