Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] 1. Coagulator design parameters

[0036] The forced loop system is equipped with a coagulator, which is located after the experimental section. Its main function is to annihilate the two-phase flow and reduce the fluid temperature. Its design parameters are:

[0037]

[0038] 2. Condenser structure design

[0039] like figure 1 Shown is the design structure diagram of the coagulator. The coagulator is mainly composed of an upper head assembly 1, an inner cylinder assembly 3, a cylinder assembly 2, a lower head assembly 4 and a support assembly.

[0040] The upper head assembly 1 mainly includes a threaded flan...

Abstract

The invention discloses a design method of a coagulation device and a voltage stabilizer of a natural circulation and forced circulation loop system. The method includes the design parameters, structure design and thermal calculation of the coagulation device, and design parameters, structure design and volume calculation of the voltage stabilizer. The method according to the design parameters and functional requirements of the natural circulation and forced experimental loop determines the design parameters of the coagulation device and voltage stabilizer of the experimental loop system, and the respectively conducts design, analysis and calculation of the coagulation device and voltage stabilizer. The invention improves the reliability of the measures set beyond design basis accident and the diversification of the nuclear power plant safety system, and has high engineering value.

Description

technical field [0001] The invention belongs to the field of reactor thermal water conservancy, in particular to a design method for a coagulator and a voltage stabilizer of a natural circulation and forced circulation loop system. Background technique [0002] The reactor can use the ability of natural circulation to export heat without relying on external power to realize the operation of the passive safety facilities of the reactor under accidents, thereby improving the safety of the reactor. [0003] Since the Fukushima incident in Japan, the international and domestic communities have put forward higher requirements for nuclear energy safety, and more and more attention has been paid to the reliability of mitigation measures for beyond-design basis accidents such as power outages and complete loss of cooling chains. . In the "General Technical Requirements for Nuclear Power Plant Improvement Actions after the Fukushima Nuclear Accident (Trial)" issued by the National N...
