    • The present invention relates to a reactor coolant pump of an integrated reactor and more specifically, to a method which excludes the loss of a large coolant and smoothly performs the maintenance of the reactor coolant pump while minimizing a maintenance space around the reactor coolant pump at a reactor coolant pump such as an integrated reactor etc. The present invention of the reactor coolant pump of the integrated reactor comprises: a motor pump which is formed on the outer side of a reactor container and circulates a fluid; an external circulation flow path which is connected to the inner side of the reactor container from outside the reactor container and circulates the fluid by the motor pump; a turbine impeller which is formed inside the reactor container to convert the power of the fluid inserted from the external circulation flow path with mechanical torque; a casing which is formed outside the turbine impeller to maintain a pressure boundary by separating the external circulation flow path and a reactor coolant system flow path; a pump impeller which is formed to circulate cooling water of a reactor coolant system by converting the mechanical rotary power into fluid power; and an integrated axis which connects the turbine impeller and the pump impeller. The present invention separately installs the motor pump with the reactor container in a proper space using the external circulation flow path which is connected with the reactor container. Therefore, accessibility for the motor pump whereby the repair of the disorder is required the most in the reactor coolant pump is improved, maintenance is easily performed, and a space for maintaining the reactor coolant pump is not required around the reactor container.
