Project Background:

Introduction of experimental device: Advanced Reactor Structural Materials High Temperature Liquid Metal Corrosion Experimental Equipment is mainly used to study the corrosion resistance of candidate materials in ultra-high temperature and atmospheric pressure liquid metal environments. The experimental subject is a high temperature and high pressure static kettle, and the experiment is conducted in a glove box, which isolates air and moisture. At the same time, the glove box provides an inert gas atmosphere to avoid danger.

Project Introduction:

The most significant feature of the fourth generation nuclear energy system is the emphasis on inherent safety, with sodium cooled fast reactor engineering having the most extensive experience and closest approach to commercialization. Meanwhile, alkali metal (lithium, sodium, potassium) heat pipe cooled reactors have attracted much attention due to their high heat transfer performance, good isothermal properties, and variable heat flux. The use of liquid metal as the heat transfer working fluid of these two types of reactors is crucial for the future development of nuclear reactors. However, liquid metal has high chemical activity and can cause serious corrosion to the core structural materials of the reactor. Therefore, exploring the compatibility between liquid metals and structural materials is of great significance.

Engineering highlights:

1) The glove box integrates reaction vessels to ensure a non-moisture and non-oxygen environment;

2) PLC control and touch screen operation is simple and convenient, and can monitor the real-time running moisture&oxygen value of 0.1PMM and the laser welding machine situation;

4) The entire process has achieved a non-moisture and non-oxygen operating environment, rather than a single point environment control;

5) The overall design adopts a modular approach, making maintenance very convenient in the later stage;

6) Connected with reaction vessels and other equipment, loading and unloading are more convenient, and the process can be controlled in a non-moisture and non-oxygen environment.
