快堆采用液态金属钠作为冷却剂,当一回路钠发生大量泄漏、快堆停堆、快堆退役或堆主回路拆除时,均存在大量被放射性沾污的钠,如何安全处理这些被放射性沾污的钠,对于核安全和环境保护都具有十分重要的意义,是快堆发展在安全方面所面临的重要问题之一。金属钠具有非常强的化学性质,长期直接贮存放射性废钠和长途运输放射性废钠均存在非常大
Fast reactors use liquid metallic sodium as a coolant. When there is a significant amount of leaking sodium in the primary circuit, a fast reactor is de-staged, the fast reactor is decommissioned, or the main loop is removed, there is a large amount of radioactively contaminated sodium. How to safely handle these radioactive contaminants Tainted sodium, which is of great significance to both nuclear safety and environmental protection, is one of the important safety issues facing the development of fast reactors. Sodium metal has very strong chemical properties, long-term direct storage of radioactive waste sodium and long-distance transport of radioactive waste sodium are very large
