Problems solved by technology

The research on the three metals of sodium metal, lead and lead-bismuth alloy as the reactor core coolant is the most abundant, but there are few studies on the use of liquid metal gallium as the reactor core coolant, and there is no addition of a small amount of gas to the liquid metal gallium. Afterwards, the research on the cycle ability, thermal conductivity and other aspects

Abstract

The invention discloses a small modular reactor coolant system. In the system, liquid metal gallium is used as a coolant, a certain amount of gas is added to the coolant, and the natural circulation capacity of the liquid gallium metal is increased by the gas, which can also increase its Disturbance to enhance the heat transfer effect; through this system, the liquid gallium metal can be repeatedly increased or decreased, and the doped gas can also be arbitrarily increased or decreased, the air pressure can be adjusted, and the heat transfer capacity and natural circulation of the liquid gallium metal under various conditions can be recorded and analyzed. It provides basic data for building flexible and diverse small modular reactors.

Description

technical field [0001] The invention relates to the field of nuclear energy, in particular to a small modular reactor coolant system. Background technique [0002] With the continuous growth of energy demand and the continuous strengthening of environmental protection awareness, the role of nuclear reactors has become more and more prominent. The rapid development of nuclear reactors also poses challenges to the thermal conductivity of the reactor coolant and the safety of the reactor. From the current point of view, most of the nuclear reactors in the world are pressurized water reactors, which use water as the reactor core coolant. However, in recent years, the research on the use of liquid metal as the reactor core coolant is constantly being carried out. . Compared with pressurized water reactors, liquid metal coolant reactors have better natural circulation capability, greater power density, operate at low pressure, have better inherent safety, smaller size and more c...
