The Browns Ferry Nuclear Plant outage planning team is considering unlatching control rods from the drywell under-vessel instead of from the refuel floor during next outage. Does anyone have an analysis of the additional dose cost and /or schedule savings for undervessel control rod unlatching compared to the refuel floor when considering the higher dose rates, and the dose accrued to remove/replace the extra shoot-out steel, etc?
