Major accident mitigation system of nuclear power station on basis of nano fluid characteristic

Abstract

The invention discloses a major accident mitigation system of a nuclear power station on the basis of the nano fluid characteristic, belonging to the technical field of nuclear power station equipment and safety. The system is composed of a superconductive tube, a heat exchanger, a radioactive grain removing device, a nano fluid preparation chamber, an ultrasonic oscillator, an air cooling tower and the like. The system can quickly adsorb energy in a containment under the major accident, hyperpressure in the containment can be alleviated by releasing and removing radioactive air and radioactive aerosol particles, nano particles can be obtained, and the efficient heat exchange medium nano fluid can be prepared to achieve the goal of alleviating the major accident of the reactor and protecting the integrity of the containment structure. A safety control function is performed and finished when major accidents happen. The system has the advantages of good backup safety, simple flow, stable performance and high reliability, is convenient to implement and simple to control, and treats wastes with wastes.

Description

technical field [0001] The invention belongs to the field of nuclear power plant equipment technology and safety, and in particular relates to a nuclear power plant severe accident mitigation system based on nanofluid characteristics. Specifically, nano-particles produced by nuclear power plants in severe accidents are used to prepare nano-fluids, and then the comprehensive characteristics of nano-fluids and superconducting heat pipes are used to realize and strengthen the passive natural circulation heat removal function of containment. In the event of a serious accident, the operation of the system performs and completes the safety guarantee function, while reducing the radiation hazard, it can also enhance the heat removal effect under the severe accident, maintain the structural integrity of the containment, and realize the suppression of the impact of the reactor accident. Mitigate accidents to achieve the purpose of protecting the public and the environment. Background...

Problems solved by technology

Radioactive aerosols are highly toxic and stay in the air for a long time. If they are not dealt with in time, they will cause a wider range of pollution, and the resulting impact is difficult to control and predict.

However, the existing removal technologies for radioactive particles, such as the French sand pile remover, the Swedish pebble remover, and the German Venturi remover, have poor removal and purification effects on nano-scale particles. Particle removal is a worldwide problem
