Description

technical field

[0001] The invention belongs to the technical field of heavy water reactor nuclear fuel loading and unloading, and in particular relates to a remote emergency operation tool and operation method for a heavy water reactor nuclear power plant loading and unloading machine. Background technique

[0002] The heavy water reactor nuclear power plant loading and unloading machine is an important equipment used to replace the nuclear fuel of the heavy water reactor. The silo is a device for storing fuel bundles on the loading and unloading machine, which is driven by a hydraulic motor during normal operation. The B rod and the L rod are the equipment for replacing the fuel bundle on the loading and unloading machine, and they are also controlled by hydraulic motors under normal conditions. The silo, B bar and L bar are the key equipment to ensure the normal progress of refueling.

[0003] In order to ensure the safety of the loading and unloading machine, the refue...
