Problems solved by technology

[0003] Most of the existing submarine reactors use pressurized water reactors. Due to the inherent characteristics of pressurized water reactors, it is difficult to miniaturize them, and the structure is bulky, and the pressurized water reactors generally operate with a forced circulation of the main pump, which brings noise problem

Embodiment Construction

[0028] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0029] On the basis of the forced circulation mode in which the main pump forces the coolant to circulate, the present invention adds a natural circulation mode in which the coolant is naturally circulated by using a branch. When switching to the natural circulation mode, the main pump is turned off, thereby eliminating the main pump Running noise.

[0030] figure 1 An embodiment according to the invention is shown.

[0031] Such as figure 1 As shown, the dual-cycle mode reactor includes a main vessel 1, a core 2, a heat exchanger 3, a main pump 4, a valve 5, and a steam turbine power generation system 6. In the primary loop system, a first branch is connected in parallel with the main pump ...

Abstract

The invention discloses a double circulation mode reactor and a control method for running noise of a reactor. The double circulation mode reactor comprises a main container, a reactor core, a heat exchanger, a main pump, a valve, a steam turbine set and a first branch, wherein the first branch is in parallel connection with the pump; the valve used for controlling the branch to switch on / off is arranged on the first branch; and a switching relation between the valve and the main pump is as follows: in a forced circulation process, the valve is switched off and the cooling agent passes by the main pump, and in a natural circulation process, the valve is switched on and the cooling agent passes by the branch. The reactor has the advantages of compact structure, small volume, low noise, simple reactor operation, wide power adjusting scope and capability of frequently adjusting power according to the requirements and running in a double circulation mode.

Description

technical field [0001] The invention relates to a reactor, in particular to a reactor capable of reducing operating noise and a method for controlling the operating noise of the reactor. Background technique [0002] The submarine reactor is a very complex and special system, which not only requires the reactor to be compact in structure, small in size, and low in noise, but also needs to be characterized by simple operation, large power adjustment range, and frequent power changes. [0003] Most of the existing submarine reactors use pressurized water reactors. Due to the inherent characteristics of pressurized water reactors, it is difficult to miniaturize them, and the structure is bulky, and the pressurized water reactors generally operate with a forced circulation of the main pump, which brings Noise problem. [0004] Therefore, it is necessary to take measures to control the operating noise of the main reactor pump. The measure for switching the operation mode of the...
