摘要： The present invention discloses a nuclear reactor coolant pump that does not rely on an electric motor, but is operated by means of driving force generated inside a nuclear power plant, so a to be capable of maintaining the safety of the nuclear reactor when the nuclear reactor is operating normally and also in the event of an accident in the nuclear reactor. The nuclear reactor coolant pump comprises: a pump impeller rotatably installed in a first fluid passage of a nuclear reactor coolant system to circulate a first fluid inside the nuclear reactor coolant system; a drive unit receiving steam from a steam generator to generate driving force to rotate the pump impeller, and rotating about the same rotating shaft as the pump impeller to transfer the generated driving force to the pump impeller; and a steam supplying unit forming a passage between the steam generator and the drive unit to supply at least a portion of the steam released from the steam generator to the drive unit.

摘要： A nuclear instrumentation system and method for locating the same are disclosed. The nuclear instrumentation system includes a source range channel, an intermediate range channel and a power range channel, wherein each channel includes one detector installed around the pressure vessel, the detectors of the power range channel and the intermediate range channel both include several fission chambers, the detectors of the intermediate range channel and power range channel share several fission chambers. Some detectors employ fission chambers, so the Gamma radiation resistance property, anti-noise property and anti-electromagnetic interference property are improved. Sharing fission chambers reduces the number of detectors to be installed, thus relieving the workload of the installation and positioning of the follow-up detector. Further, the present application increases the number of some channels, which increases the redundancy, improves system reliability.
