标准摘要
[中文适用范围]： 本国际标准规定了有关核设施通风系统设计和使用的适用要求，如热室、核燃料制造和检查实验室、钚处理设施、后处理厂、浓缩设施、核废物处理站、储存设施、通风和安全壳系统的目的是确保安全功能并保护工人、公众和环境免受这些设施运行过程中造成的放射性污染的扩散。 本国际标准不适用于核电站和一些在事故情况下可能出现高压的研究堆的安全壳外壳。 它确实适用于这些设施的辅助房间。 确保核反应堆安全功能的通风系统的设计和使用要求将在另一项国际标准中制定。 [外文原描述]： ISO 17873:2004 specifies the applicable requirements concerning the design and use of ventilation systems in nuclear installations such as hot cells, nuclear fuel fabrication and examination laboratories, plutonium-handling facilities, reprocessing plants, enrichment facilities, nuclear-waste treatment stations, storage facilities, etc. The purpose of ventilation and containment systems is to ensure safety functions and protect workers, public and environment against the spread of radioactive contamination resulting from the operational processes of these installations. ISO 17873:2004 does not apply to the containment envelope of nuclear power plants and some research reactors where high pressure can occur during accident scenarios. It does apply to auxiliary rooms of these facilities.
英文名称Nuclear facilities — Criteria for the design and operation of ventilation systems for nuclear installations other than nuclear reactors
