Embodiment 1

[0024] Such as figure 1 , a passive balance system for a nuclear reactor, comprising: a nuclear power plant 1 having a nuclear reactor 11; a balance structure 2, in which the nuclear power plant 1 is fixed in the balance structure 2; a support mechanism 3, which is connected by a movable hinge 4 and supports the balance structure 2; The hinge 4 is hinged with the support mechanism 3 in a manner that can automatically rotate relative to the support mechanism 3 , and the bottom of the movable hinge 4 is connected to the top of the balance structure 2 . The nuclear reactor passive balance system can realize the nuclear reactor 11 in a balanced state without external force, so as to prevent the nuclear reactor 11 device from tilting or even overturning caused by the marine environment. The balance structure 2 rotates the movable hinge 4 under the action of gravity of the nuclear power plant 1, so that the nuclear reactor 11 is in a vertical or nearly vertical state. The bottom of...

Embodiment 2

[0030] Since the offshore nuclear power platform is easily affected by wind and waves, and the offshore nuclear power platform may also be in a moving state, the balance structure 2 is prone to swing displacement in the horizontal direction, making the nuclear reactor 1 in a state of vibration. Further, as image 3 As shown, in Embodiment 2, a weight 6 is added on the basis of the passive dynamic balance system of the nuclear reactor in Embodiment 1. The weight is a solid iron ball, and the mass of the solid iron ball is smaller than that of the nuclear power system. A weight 6 is flexibly connected to the bottom of the balancing structure 2 . The weight 6 plays the role of reducing the swing amplitude of the balance structure 2 under the action of its own inertia, further reducing the inclination angle of the nuclear reactor 1 . In addition, the weight 6 can also counteract the kinetic energy generated by the swing of the balance structure 2 to play a stabilizing role. exis...

Abstract

The invention relates to a nuclear reactor passive balance system. The nuclear reactor passive balance system comprises a nuclear power apparatus, a balance structure, a supporting mechanism and a movable hinge, wherein the nuclear power apparatus has a nuclear reactor; the nuclear power apparatus is fixed in the balance structure; the supporting mechanism is connected and supports the balance structure by virtue of the movable hinge; and the movable hinge can be hinged with the supporting mechanism in a manner of automatically rotating relative to the supporting mechanism, and the bottom of the movable hinge is connected with the top of the balance structure. By adopting the nuclear reactor passive balance system, the balance state of the nuclear reactor can be realized without external force, so that the inclination and tumbling of the nuclear reactor apparatus caused by an ocean environment can be prevented.

Description

technical field [0001] The invention relates to the field of nuclear engineering, in particular to a nuclear reactor passive balance system and a nuclear reactor passive balance method. Background technique [0002] The marine environment will cause sway, tilt and heave effects on the offshore nuclear reactor platform and devices, especially the inclination caused by the marine environment to the nuclear reactor device will easily lead to a nuclear reactor core accident, which will bring a great test to the safe operation of the nuclear power plant. The application and development of offshore nuclear power plants are limited. Existing offshore nuclear power plants have set clear requirements on the inclination angle, which limits the allowable inclination angle of the device. Contents of the invention [0003] The invention aims to provide a nuclear reactor passive dynamic balance system to solve the inclination problem of the nuclear reactor device caused by the marine e...
