制御棒が引き抜かれたのと同様の状態となる。Then, the pressure inside the case becomes higher than that inside the sealed cylinder. Here, the pressure inside and outside the cylinder is balanced by shrinking the closed cylinder in its axial direction. As a result, some of the liquid lithium inside the sealed cylinder is pushed out and returned to the tank. The neutron absorber in the case, that is, the lower end of the liquid column of liquid lithium, is raised by that amount, resulting in a state similar to when a control rod is pulled out in a conventional nuclear reactor.

の状態となる。Further, when the control device discharges the coolant in the case, the restoring force of the closed cylinder pushes out the coolant that has been injected into the case and flows back into the reactor vessel. When the closed cylinder is expanded, liquid lithium flows into it from the tank. That is, the lower end of the liquid column of liquid lithium in the case has been lowered, resulting in a state similar to when a control rod is inserted in a conventional nuclear reactor.

液体リチウムの一部は押し呂され。Here, the pump 22 and valve 24 of the controller 13 are used to control the output of the nuclear reactor. The pump 22 is started to suck the coolant in the reactor vessel 2 through the pipe 16 and inject it into the lower space 23 in the case 17 via the pipe 15. Then,
The pressure within the lower space 23 becomes higher than that within the sealed cylinder 20. Here, the bellows joint 19 of the closed cylinder 20 is compressed, and the closed cylinder 20 contracts in its axial direction, thereby balancing the pressure inside and outside the cylinder. Due to the shrinkage of the sealed cylinder 20, a portion of the liquid lithium inside the cylinder is pushed out.

の状態となる。Furthermore, when the pump 22 is stopped and the valve 24 is opened, the hermetic cylinder 20 expands due to the restoring force of the bellows joint 19 of the hermetic cylinder 20, and as a result, the coolant injected into the lower space 23 is discharged. Extruded, piping 15, valve 24. It is refluxed into the reactor vessel 2 via the pipe 16. As a result, the pressure in the lower space 23 is lowered. Also,
When the sealed cylinder 20 is expanded, the sealed cylinder 2 is removed from the tank 21.
Liquid lithium flows into 0. That is, case 17
The lower end of the liquid lithium column inside the reactor has been lowered, similar to when a control rod is inserted in a conventional nuclear reactor.

Therefore, the output of the nuclear reactor can be controlled in the same manner as the conventional insertion and removal of control rods into the reactor core.
また、原子炉停止時にはポンプ２２を停止させ、弁２４
