摘要： The present disclosure provides a refuelling device for lifting a fuel rod assembly from a reactor core of a nuclear power generation system in a deployment location and transporting it to a storage location. The refuelling device comprises a device body having an open base and defining a chamber for housing a coolant. A sealing plate is movable between an open position in which the chamber is open and a closed position in which the chamber is sealed. The device further comprises a shielding element formed of radioactive shielding material and moveably mounted within the chamber. It has a storage cavity having an open lower end, the shielding element being movable between a retracted position in which it is fully contained within the chamber and an extended position in which it extends from the chamber through the open base of the device body. The device further comprises a rod lifting system having a rod connector for releasable connection to the fuel rod assembly and configured to raise the fuel rod assembly to within the storage cavity when the device is in the deployment location, the sealing plate is in the open position and the shielding element is in its extended position.

摘要： A method of constructing a nuclear reactor module includes providing formwork defining a chamber in which is mounted a nuclear reactor comprising a nuclear reactor pressure vessel configured to contain nuclear fuel when in use, the formwork being housed within a containment structure configured to contain an internal pressure generated by an escape of coolant from a reactor coolant circuit. The method further includes filling one or more voids within the formwork with concrete through at least one concrete supply pipe that extends from outside of the containment structure, through the containment structure, and to the formwork; and venting the one or more voids within the formwork through one or more vent pipes, thereby forming a concrete support structure for the nuclear reactor.
