The requirements and guidance in this document are consistent with modern national and international practices addressing issues and elements that control and enhance nuclear safety. With a graded approach, the application of requirements is commensurate with the risks and particular characteristics of the facility or activity.Īn applicant or licensee may put forward a case to demonstrate that the intent of a requirement is addressed by other means and demonstrated with supportable evidence. The use of a graded approach is not a relaxation of requirements. Licensees are expected to review and consider guidance should they choose not to follow it, they should explain how their chosen alternate approach meets regulatory requirements.įor existing facilities: the requirements contained in this document do not apply unless they have been included, in whole or in part, in the licence or licensing basis.Ī graded approach, commensurate with risk, may be defined and used when applying the requirements and guidance contained in this regulatory document. It also provides more information about how CNSC staff evaluate specific problems or data during their review of licence applications. Guidance contained in this document exists to inform the applicant, to elaborate further on requirements or to provide direction to licensees and applicants on how to meet requirements. It is intended for inclusion in licences as either part of the conditions and safety and control measures in a licence, or as part of the safety and control measures to be described in a licence application and the documents needed to support that application. This document is intended to form part of the licensing basis for a regulated facility or activity. In this document, the terms category I to V sources are used as defined in the IAEA’s Code of Conduct on the Safety and Security of Radioactive, IAEA Safety Guide RS-G-1.9, Categorization of Radioactive Sources or IAEA/TECDOC-1344, Categorization of Radioactive Sources. Part A of this document applies to category 1, 2, and 3 sources and provides "prudent management practices" for category 4 and 5 sources. Part A of this document applies to sealed radioactive sources (encapsulated or solid) and does not apply to unsealed radioactive substances. This document supersedes CNSC guidance documents G-208, Transportation Security Plans for Category I, II, or III Nuclear Material, and G-274, Security Programs for Category I or II Nuclear Material or Certain Nuclear Facilities, and REGDOC-2.12.3, Security of Nuclear Substances: Sealed Sources. Category I, II and III nuclear material are defined in appendix E to this guide. This document also sets out guidance to help applicants for a CNSC licence to transport Category I, II or III nuclear material to prepare and submit a "written transportation security plan" that meets the requirements of section 5 of the Nuclear Security Regulations. This document sets out guidance to help applicants for a Canadian Nuclear Safety Commission (CNSC) licence in respect of Category I or II nuclear material – other than a licence to transport – or a nuclear facility consisting of a nuclear reactor that may exceed 10 MW thermal power during normal operation, to prepare and submit the security information to be included with the application, pursuant to the Nuclear Safety and Control Act. For sealed sources, this document applies to transport by road within Canada only (there are other instruments and technical instructions that regulate the safe transport of dangerous goods by sea, air and rail). Part B of this document also provides information and guidance on how to comply with the minimum security measures, including measures related to transport vehicles, containers and security plans. Part A of Regulatory document REGDOC-2.12.3 version 2, Security of Nuclear Substances: Sealed Sources and Category I, II and III Nuclear Material sets out the minimum security measures that licensees must implement to prevent the loss, sabotage, illegal use, illegal possession or illegal removal of sealed sources during their entire lifecycle, including while the sources are in storage, transport or being stored during transportation. The full list of regulatory document series is included at the end of this document and can be found on the CNSC’s Regulatory documents Web page. This regulatory document is part of the CNSC’s Security series of regulatory documents, which also covers high-security facilities and site security.
