Nuclear facilities — Criteria for design and operation of confinement systems for nuclear worksite and for nuclear installations under decommissioning
This document specifies the requirements applicable to the design and use of airborne confinement systems that ensure safety and radioprotection functions in nuclear worksites and in nuclear installations under decommissioning to protect from radioactive contamination produced: aerosol or gas. The purpose of confinement systems is to protect the workers, members of the public and environment against the spread of radioactive contamination resulting from operations in nuclear worksites and from nuclear installations under decommissioning. The confinement of nuclear worksites and of nuclear installations under decommissioning is characterized by the temporary and evolving (dynamic) nature of the operations to be performed. These operations often take place in area not specifically designed for this purpose. This document applies to maintenance or upgrades at worksites which fit the above definition. NOTE The requirements for the design and use of ventilation and confinement systems and for liquid confinement in nuclear reactors or in nuclear installations other than nuclear worksites and nuclear installations under decommissioning are developed in other ISO standards.
ISO 16647:2018 provides requirements and guidance for the design and operation of airborne confinement systems used during activities at nuclear worksites and nuclear installations under decommissioning. The standard focuses on protecting workers, the public and the environment from radioactive contamination in the form of aerosols and gases. It addresses the temporary, evolving (dynamic) nature of worksite operations and applies to maintenance, upgrades and decommissioning tasks often carried out in areas not originally designed for radiological operations.
ISO 16647:2018 organizes technical requirements and recommendations across the lifecycle of confinement systems. Key topics include:
