摘要: 简述了中国实验快堆的技术原则、设计特点和工程技术方案．该堆采用铀钚氧化物燃料，奥氏体３１６（Ｔｉ）不锈钢为燃料包壳、堆芯结构材料和钠冷池式结构．同时，在堆芯设置了非能动的余热排出系统．该设计方案在技术上是合适、可行的，在安全上是有保障的． This paper outlines briefly technical, principle,design feature and technical scheme of CEFR. In CEFR, the fuel is plutonium uranium mixed dioxide (Pu.U)O 2. The material of fuel clad and core structure is stainless steel 316(Ti) and sodium cooling pool type configuration and the passive residual heat removal system is installed in core. This design scheme is feasible technolugically and its safety is trusty.
