Molten salt reactor core and molten salt reactor system

Abstract

The invention discloses a molten salt reactor core and a molten salt reactor system. The molten salt reactor core comprises a reactor core active area, a reflecting layer, a coolant inlet and a coolant outlet, the reflecting layer is arranged around the outer side of the reactor core active area, and a control drum is arranged in the reflecting layer; the reactor core active area is provided with a coolant pipeline area and a fuel molten salt area, the coolant pipeline area is provided with a plurality of coolant pipelines, and helium and xenon mixed gas or supercritical carbon dioxide circulates in the coolant pipelines; the fuel molten salt area is filled with fuel molten salt; the volume ratio of the coolant pipeline area to the fuel molten salt area is (6-9):10; and the top end of the coolant pipeline is connected with the coolant outlet, and the bottom end of the coolant pipeline is connected with the coolant inlet. The molten salt reactor core is simple in structure, the heat exchange efficiency of the reactor core is improved, the construction cost and the construction threshold of the reactor core are reduced, operation is safer, and meanwhile the electric power of a molten salt reactor system is improved to a great extent.

Description

technical field [0001] The invention relates to a molten salt reactor core and a molten salt reactor system. Background technique [0002] Nuclear power has the advantages of high energy density, stable working performance, and good environmental adaptability, which can provide a strong guarantee for deep space, deep sea exploration, and stable energy supply in remote areas. Different from conventional large commercial reactors, small reactors have advantages in terms of construction period, construction cost risk, operational safety and deployment flexibility. Small reactors have attracted widespread attention from countries all over the world, especially countries with developed nuclear energy, such as the United States and Russia. The United States has launched space reactor research projects since the 1960s, and has developed a variety of space reactors, including the SNAP series of space reactors, 710 space reactors, and SP-100 space reactors; after 2000, the Prometheu...
