Huclear Instrumentation power range crannel NI 6 was calitrated t.o 25% power while power range channel NI-5 was ec;ntrolling Integrate :
Control System's (ICS) functions. After N1-6 calit> ration was cc u pletel, ICS control was switched from 13I-5 to NI-6 prior to changing the ec.ntrol cod drive system cont rol to the manual ;csition. Since den.and was at 46% tefore the switch, the ICS systen "saw" that reactor power had fropped lower than denand (i.e. 25% vs. h6%) and started pullir.g control rods to increase power. Henctor Protection System (RIS)
