NF ISO 7753, M60-481 (09/2023)

This document gives the requirements and recommendations relating to the use of SYDAC in the context of the operation of a nuclear installation. The requirements and recommendations relating to the design of SYDACs are given in the IEC 60860 standard. This document applies to operations involving fissile materials outside nuclear reactors, but within the limits of nuclear installations. This document applies when a need for SYDAC has been established. Information relating to the need for SYDAC is given in Annex C. This document does not include details relating to administrative aspects, which are considered to be the responsibility of a rigorous management system (ISO 14943 gives details relating to these aspects). Details relating to nuclear accident dosimetry and personnel exposure assessments are not the subject of this document. This document is devoted to systems sensitive to the flow of neutrons and gamma radiation. Specific detection criteria can also be met with integrative systems; systems detecting neutrons or gamma radiation can also be used. Similar considerations then apply.
