Fluorine salt test system and method based on molten salt rector passive residual heat removal system

Abstract

The invention discloses a fluorine salt test system and a method based on a molten salt rector passive residual heat removal system. The fluorine salt test system comprises an argon gas assist systemformed of a argon gas bottle, a buffer tank, a argon gas pipe and a valve on the pipe, a storage tank used for storing fluorine salt for a long time, a simulated core tank used for simulating the relative position of the molten salt rector core, a heat pipe can with the quick heat radiation effect, a contrast tank used for playing a contrast effect on the heat pipe can and a fluorine salt pipe system connecting fluorine salt pipes of fluorine salt tank with the valve. The invention also provides the test method of the test system, which comprises the following steps: heating the fluorine saltin the storage tank into liquid state, entering the simulated core tank through the fluorine salt pipe under the pressure difference of the argon gas, flowing into the contrast tank or the heat pipe can to perform test under the action of the gravity, and finally flowing back to the storage tank along the fluorine salt pipes. The fluorine salt test system provided by the invention can bear high-temperature work condition, the test process operation is simple and the system loop is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of molten salt reactor passive waste heat discharge system, in particular to a fluoride salt experiment system and method based on the molten salt reactor passive waste heat discharge system. Background technique [0002] With the development of new-type molten salt reactors, related molten salt experiments are also being carried out in full swing. Fluoride salts are generally used as coolants for molten salt reactors in the world, so fluoride salts are used in relevant experimental research. At present, there are very few experiments on fluoride salts in the world, and the relevant experimental data of fluoride salts is extremely scarce, so it is particularly important to build a large-scale experimental bench. The circuit design of the fluoride salt experiment plays a vital role in the smooth development of the experiment. A good design scheme can not only save costs, but also an important guarantee for th...

Problems solved by technology

This system is safe, reliable, and easy to operate, but it is only suitable for sodium with a low melting point and less corrosiveness, and it is no longer suitable for fluorine salts with special corrosiveness and high melting point

[0004] Another example is the Chinese patent CN103280247A which provides a passive waste heat removal system for fluorine-salt cooling high-temperature reactors, which mainly includes an air cooling tower, a molten salt pool, a support ring, a splitter plate, and a heat exchanger. ...
