Nuclear reactor oxygen control type liquid metal used under 200-300 DEG C and compatibility process thereof

Abstract

The invention discloses a nuclear reactor oxygen control type liquid metal used under 200-300 DEG C and a compatibility process of the nuclear reactor oxygen control type liquid metal used under 200-300 DEG C. The nuclear reactor oxygen control type liquid metal comprises, by weight percentage, 0.2-0.4 wt.% of Ag, 3.0-5.0 wt.% of Sb, 1.0-2.0 wt.% of Mn, 10.0-15.0 wt.% of Bi, 8.0-12.0 wt.% of Cd, 2.0-3.0 wt.% of Ga, 20.0-30.0 wt.% of Pb and the balance tin. The oxide composition for controlling the oxygen activity is composed of 10.0-12.0 wt.% of PbO, 2.0-5.0 wt.% of CuO, 1.0-4.0 wt.% of Sn2O3, 5.0-8.0 wt.% of AgO, 10.0-20.0 wt.% of ZnO and the balance Fe2O3. When the scheme is applied to liquid metal and pipeline design in the field of nuclear power, the equipment is simple, the construction cost is low, and the heat transfer performance is good; and under the working temperature of 200-300 DEG C, the structure (liquid metal plus oxygen control module plus stainless steel pipeline) can be used for 10 years without major overhaul.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a tin alloy. Background technique [0002] With the rapid development of industrial technology, the demand for energy is getting stronger and stronger. However, my country's traditionally coal-based energy structure has brought serious air pollution. To fundamentally reduce air pollution in our country, we must reduce the proportion and share of coal burning in primary energy. It can be expected that green energy will occupy a higher proportion in the future, which will play an important role in fundamentally solving air pollution and mitigating future climate change. There are two types of nuclear energy: fission energy and fusion energy. At present, controllable fusion energy is in the research stage, and commercial nuclear energy projects are all based on fission. A country's national defense strength and national economic level can be measured from the use of nuclear energ...

Problems solved by technology

But it is regrettable that the corrosion and dissolution of liquid metal heat transfer materials in stainless steel pipes have not been well resolved.

From the perspective of material science, this patent proposes an oxygen-controlled liquid metal for nuclear reactors to solve the chemical compatibility problem of liquid metal in stainless steel pipes at high temperatures
