PURPOSE: A coolant recovery system of a reactor coolant pump is provided to collect coolant discharged through a draining channel in a reactor drain tank, thereby preventing the coolant from coming out to the outside. CONSTITUTION: A drain channel (211) is formed at least one of a pump casing (12) and a seal housing (21) for collecting coolant leaked between the pump casing and the seal housing in a reactor drain tank such that the coolant can be collected in the reactor drain tank even when caskets (26,27) that are installed between the pump casing and the seal housing are damaged. |
