Our procedures state the similar, more than 1 rod dropped at power, manually trip the reactor. If a rod were to drop during initial approach to criticality after refueling or physics testing, the procedure for that requires a manual reactor trip.
There is no procedural requirement to trip the reactor during other startups for a dropped rod, however we would have pre-determined actions/termination criteria from Operations and in the IPTE to either manually trip or insert all banks to zero if that were to happen. There is also no specific power level where this would or wouldn't apply. We usually terminate the IPTE for startup once the Main feed Reg Valves are put in service ~25-28% RTP.
