Based on the background discussed earlier regarding the effect of radiation on the corrosivity of liquid metal coolants, the specific impacts of radiation on such coolants can be categorized as follows: Radiation stability. Liquid metals have a single-atom, disordered structure, and the structural defects induced by radiation are negligible; therefore, they exhibit excellent overall stability under high-radiation conditions, and do not undergo significant radiation-induced decomposition like compound media do. Corrosion-related effects: Under normal reactor operating conditions, irradiation does not significantly enhance the corrosion susceptibility of liquid metals; only in specific scenarios (such as when the protective film on a solid surface is stripped off by irradiated particles) could there theoretically be a slight acceleration of corrosion. No significant increase in corrosion was observed in actual reactor tests. Nuclear activation and radioactive by-products: In sodium-cooled reactors, sodium absorbs neutrons to produce the highly radioactive ²⁴Na; activated products such as ²²Na may also be generated, increasing the radiation protection challenges in the primary loop. Lead-bismuth alloy coolants produce the radioactive isotope polonium-210 under irradiation, and thus require strict control. Impact on diffusion and thermal properties: Irradiation has a minimal effect on the solute diffusion coefficient in liquid metals; it does not significantly alter their key thermal properties such as high thermal conductivity and low melting point, thereby ensuring stability in the heat-carrying capacity of the coolant.
