ISO 26802:2010规定了与核电厂和研究反应堆安全壳和通风系统的设计和运行相关的适用要求，并考虑了以下因素。 对于核电站，ISO 26802:2010仅针对具有基于IAEA建议的二次约束系统的反应堆。 对于研究反应堆，ISO 26802:2010特别适用于意外情况可能对安全壳屏障的完整性或密封性造成挑战的反应堆，即可能发生高压或高温瞬态的反应堆，以及需要隔离安全壳厂房和关闭安全壳厂房相关通风系统的反应堆。 ISO 26802:2010的要求适用于在意外情况下压力或温度升高不会损坏通风系统的研究反应堆，尽管ISO 17873中给出了适用于通风系统设计和使用的要求。

ISO 26802:2010 specifies the applicable requirements related to the design and the operation of containment and ventilation systems of nuclear power plants and research reactors taking into account the following. For nuclear power plants, ISO 26802:2010 addresses only reactors that have a secondary confinement system based on IAEA recommendations. For research reactors, ISO 26802:2010 applies specifically to reactors for which accidental situations can challenge the integrity or leak-tightness of the containment barrier, i.e. in which a high-pressure or -temperature transient can occur and for which the isolation of the containment building and the shut-off of the associated ventilation systems of the containment building is required. The requirements of ISO 26802:2010 apply to research reactors in which the increase of pressure or temperature during accidental situations do not risk damaging the ventilation systems, although the requirements applicable for the design and the use of ventilation systems are given in ISO 17873.
