A self-sustaining update module device for molten salt fuel

Abstract

The invention is a molten salt fuel self-sustaining renewal module device. The invention belongs to the technical field of nuclear fuel renewal cycle, and the device comprises: a removal area, a first reaction container, a first heating layer, a second reaction container, a second heating layer, molten salt flowing through pipelines, a waste area, a radiation shielding area, Raw material area, supplementary area, auxiliary area, molten salt inlet, cooling fins and molten salt outlet. The present invention uses the electric power generated by the molten salt reactor itself, the waste heat of the molten salt fuel itself, and the decay heat generated by the fission products as energy sources to update the molten salt fuel online, remove the fission products, and replenish fissionable and fissile substances. The combined use of small molten salt reactors can realize the modularization, convenience, and mobility of small molten salt reactors. Regular replacement of molten salt update modules can make molten salt reactors continue to operate stably during their service life. When needed, the collected fission products can be further processed by recovering the molten salt renewal module, so as to facilitate the recycling of fuel.

Description

A self-sustained updating module device for molten salt fuel technical field The present invention relates to the technical field of nuclear fuel renewal cycle, is a kind of molten salt fuel self-sustaining renewal module device. Background technique [0002] In the design of large nuclear reactors that use molten salt as fuel, additional molten salt may be built outside the nuclear reactor On-line processing facilities, through the chemical treatment of molten salt spent fuel, to remove fission products and increase fissionable nuclides, so that in During the operation of the molten salt reactor, the change of the composition of the molten salt fuel after such immediate on-line or periodic processing It is guaranteed to be within a small fluctuation range, thereby ensuring the stable power output of the molten salt reactor. However, the molten salt online processing facilities are generally For a larger plant area, its construction will increase the construction cost...

AI Technical Summary

Problems solved by technology

However, molten salt on-line processing facilities are generally relatively large-scale factories. On the one hand, their construction will increase the construction cost of nuclear power facilities, and on the other hand, it is not conducive to the application and promotion of molten salt reactors.
