👉 Radiation fluid, also known as radioliquid or radioactive coolant, is a specialized medium used in nuclear reactors to transfer heat generated by the fission process. Unlike conventional coolants like water or gas, which primarily transport heat through convection, radiation fluid can efficiently conduct heat through electromagnetic radiation. This is particularly crucial in high-temperature environments where other cooling methods might be insufficient or impractical due to the risk of boiling or phase change. Commonly used in advanced reactor designs, such as molten salt reactors and some high-temperature gas-cooled reactors, radiation fluid ensures effective heat removal from the reactor core, maintaining safe and efficient operation.
