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.

North Anna's AP will have the operator trip the reactor with more than one rod dropped. There is no guidance on tripping or not tripping the reactor depending on what power level the reactor is at or whether a startup is in progress. It does make sense to me though that tripping the reactor with a dropped rod during startup is the right thing to do. If I were going to define"startup" in the context of a dropped rod recovery, I would include the approach to critical and operation below the POAH. Maybe up to 5%. My concern is that the dropped rod could take the reactor subcritical and pulling it could be an approach to critical outside of a procedure. Due to temperature feedback, this would not be as likely in the power range. Our reactor is quite stable at 7% on the steam dumps so that would be where I might call the end of startup.

FCS has two requirements regarding a dropped rod. First, if we drop more than one rod at power, we trip the reactor. Second, if we drop a single rod during startup, we trip the reactor. What we don't have is a definition of when startup is considered complete, with regards to a dropped rod.

Do other plants have similar requirements and do you have a definition of when startup is complete with regards to a dropped rod?

For Surry: If we drop more than one at power, we trip as well. If we drop only one, our TS allow us to look at hot channel factors further and (if we meet some conditions) continue operating with a dropped rod (happened in 2006 for 19 days). If a rod is dropped during a startup or physics testing, the reactor will be tripped. Following recovery of a dropped rod, the recovery is considered complete when the follow up test to verify that the rod is working properly is complete. So it wold depend on the failure.
