标准摘要
[中文适用范围]： 对于具有包覆镁合金的金属天然铀燃料的反应堆（类型 1）和具有包覆不锈钢的浓缩铀氧化物燃料的反应堆（类型 2），补充的目的是在 IEC 出版物中给出的建议中添加建议。 [外文原描述]： Applicable more particularly to instrumentation for gas-cooled graphite-moderated reactors, Type 1: reactors having metallic natural uranium fuel clad with magnesium alloy, and Type 2: reactors having enriched uranium oxide fuel clad with stainless steel. The IEC 60231 series of standards is no longer up-to-date and will not be revised by IEC. The standards are maintained for the time being for bibliographical purposes and because they were used in the past for the design of nuclear power plants which are still in operation.
