Description
Technical field
This disclosure relates to the material properties test technical field of experiment equipment in liquid lead bismuth corrosion and ion irradiation environment,
More particularly to a kind of control oxygen liquid lead bismuth is corroded and ion irradiation cooperating research experimental provision.
Background technique
Liquid lead bismuth eutectic (LBE) has good neutronics, physics and chemical property, is that lead base generally acknowledged at present is cooling
Reactor (LFR) and the preferred coolant material of accelerator-driven sub-critical system (ADS), while being also a kind of important ADS scattered
Split target material.It is served in the working condition that LBE is faced as the structural material in coolant or the Advanced Nuclear Energy Systems of spallation target
Very severe, not only by high temperature, strong irradiation, but also there are also deep-etchings caused by liquid lead bismuth.Liquid lead bismuth is to metallic based structures
The corrosion behavior of material is broadly divided into oxidation corrosion and dissolved corrosion, related with the oxygen concentration dissolved in liquid lead bismuth.In height
Oxygen (> 10-6Wt%) in environment, the metallic atom of metallic based structures material internal is inwardly spread to external diffusion, O ion, in material
Surface will form metal oxide layer, oxide layer, which grows to certain thickness and is easy to happen, to fall off, so increase line clogging windward
Danger.In hypoxemia (< 10-8Wt%) in environment, metal material Fe, Ni and Cr element can largely be dissolved in corrosive medium, cause to tie
Constitutive element part mass loss, to reduce the mechanical load ability of material.Based on the development of control oxygen technology, by accurately controlling liquid
Dissolved oxygen concentration in lead bismuth is allowed to form one layer of densification, the moderate metal oxide layer of thickness on the surface of the material, can be effectively prevented
Or liquid lead bismuth is delayed to corrode.In neutron irradiation environment, the irradiation defect that can be generated inside structural material and surface oxide layer
(spacer and vacancy), due to irradiating enhanced diffustion effect, oversaturated defect will lead to the expansion of alloying element in metallic matrix
Scattered coefficient greatly increases.In addition, the highdensity dislocation structure that irradiation is formed is considered as a metal ion species and the diffusion of O ion
Express passway, it can thus be anticipated that, neutron irradiation and liquid lead bismuth corrosion there is certain synergistic effect in the material.
The synergistic effect effect is as standby with very one of critical issue of high priority in the design of such nuclear-energy plant and construction
Paid attention to, but seldom to the research of neutron irradiation/liquid lead bismuth corrosion synergistic effect at present, acquired experimental data is also very
It is limited, it is part of the reason is that due to related experiment device shortage.Chinese patent 2013106302246 mentions a kind of ion
Irradiation and liquid lead bismuth corrosion synergistic effect research experiment device, cooperate with effect with liquid lead bismuth corrosion although realizing irradiation substantially
It should study, but lack liquid lead bismuth oxygen concentration control system, the synergistic effect that can only generally carry out under saturated oxygen concentration conditions is ground
Study carefully.In addition, current liquid lead bismuth circuit generally also lacks necessary Fluid pressure detection system, experiential function is relatively single.
