Overview and use of model regulations for the predisposal management of radioactive waste Primary Legislation (Law, Decree etc) Subordinate Legislation (Regulations) Guidance documents (Guidance, Code of Practices, etc) Legislation - Hierarchy
Overview and use of model regulations for the predisposal management of radioactive waste • Legislation normally comprises of primary legislation and sub-ordinate legislation, the provisions both of which are legally binding • Primary and sub-ordinate legislation is usually supplemented by Guidance Documents (e.g. ‘Codes of Practice’). • Such guidance documents give practical advice or recommendations on ways by which the legal requirements of the primary and sub-ordinate legislation can be met.
Overview and use of model regulations for the predisposal management of radioactive waste Primary Legislation / The Law • The legal basis for regulating Safety is provided by primary legislation generally referred to as the ‘Law’ and issued by the supreme law-making organ of the government (i.e. the national legislature or parliament). • Examples: • Law on Radiation Protection, Human Health and Environmental Protection; • Law on the Use of Atomic Energy.
Overview and use of model regulations for the predisposal management of radioactive waste Sub-ordinate Legislation / The Regulations • Sub-ordinate or Secondary legislation, often known as Regulations or Decrees according to the country’s legal system, are issued by a Government Minister or other ‘Competent Authority’ (often the regulatory body) as specified under the Law. • In this case they establish the general principles (if not already established under the Law) and specify particular requirements necessary to achieve compliance with the provisions of the Law. • Regulations are normally of general application but may authorize the imposition of site-specific conditions and requirements or in some cases be site specific. • They are subject to change more frequently than the primary law.
Overview and use of model regulations for the predisposal management of radioactive waste Sub-ordinate Legislation / The Regulations • There may be one or more regulations for implementation of the Law. • Preparation of the regulations may require extensive co-operation and consultations with other national organizations. • This can be facilitated if there is an advisory body. • However it may be difficult to set up such an advisory body in some countries. • In such cases the organization preparing the regulations must find some other means to ensure that the regulations cover all necessary aspects, do not conflict with other regulations under other laws and do not place unnecessary restrictions on operators.
Overview and use of model regulations for the predisposal management of radioactive waste Sub-ordinate Legislation / The Regulations • Regulations should be written in straightforward language so that users and others can clearly understand them. • Users should know what they have to do to comply and be able to demonstrate they do. • Lack of clarity or ambiguity in regulations can lead to failure by the regulators to enforce them when poor practices are observed.
GSR Part 1 Requirement 32 – Regulations and Guides • The regulatory body shall establish or adopt regulations and guides to specify the principles, requirements and associated criteria for safety upon which its regulatory judgments, decisions and actions are based
GSR Part 1 Requirement 33 and 34 – Preparation of Regulations Promotion of regulation R34 Review of regulation R33 • Process for regulations • Consultation • International standards • Feedback from experience • Framework for authorization • Consistent • Comprehensive • Graded approach ◄ 1/2/2020 11
Overview and use of model regulations for the predisposal management of radioactive waste Sub-ordinate Legislation / The Regulations
Overview and use of model regulations for the predisposal management of radioactive waste Regulatory Strategies • What is a regulatory strategy? • An approach to regulation that determines the overarching types of demands that are made on licensees/ applicants • It is more specific than a regulatory mandate—which is the scope of responsibility given by the government to the regulator, and • More general than regulatory methods—which are the ways that the regulator determines if operators are fulfilling demands (inspections, document reviews etc.)
Overview and use of model regulations for the predisposal management of radioactive waste Importance of Regulatory Strategies • Strategies affect the behavior of licensees and therefore have an impact on safety • Development of regulatory framework is based upon the adopted strategy • Strategies are a major determinant of how a regulator carries out oversight • e.g. resources used, types of expertise needed
Overview and use of model regulations for the predisposal management of radioactive waste Context Influencing the Regulatory Strategy • Regulatory mandate • Nature of the nuclear industry • Culture and history • of the country, • of the regulatory agency, and • of the facilities and activities being regulated
Overview and use of model regulations for the predisposal management of radioactive waste Alternative Regulatory Strategies • Prescriptive • Case-based • Outcome-based • Risk-based • Process-based • Licensee self-assessments
Overview and use of model regulations for the predisposal management of radioactive waste Strategies for Establishing Practice-Specific Regulations and Guides • The RB has several options : • Adopt international safety standards • Develop its own national practice-specific regulations, codes and guides • Using standards from the industry or independent organizations • The option chosen should be decided on a risk informed basis
Overview and use of model regulations for the predisposal management of radioactive waste Adopt International Safety Standards into National Regulations and Guides • Depending upon the RB’s enabling legislation, the RB may be able to reference or quote in regulations and license conditions IAEA practice-specific safety standards, thereby making these into legal requirements. • The disadvantage of doing so is that when the IAEA changes a safety standards, this will call for the RB to make corresponding changes to its regulations and guides.
Overview and use of model regulations for the predisposal management of radioactive waste Develop National Practice-specific Regulations, Codes and Guides • National regulations, codes and guides are usually desirable because they refer to specific national circumstances. • It is also advantageous to prepare regulations, codes and guides in local languages and include photographs and illustrations that are more relevant than those that are prepared outside the State.
Overview and use of model regulations for the predisposal management of radioactive waste Develop or adopt industry standards • The RB may also take the approach of developing or adopting industry standards produced by medical, academic, or professional standards associations such as those developed and prepared by the ISO, IEC, etc. • The development of consensus industry standards is a process usually managed by a standards agency. The process should include participation by RB experts at drafting meetings and the RB should have input into the final version.
Overview and use of model regulations for the predisposal management of radioactive waste Consultation about Regulations and Guides • Having taken the decision to develop or revise regulations, the RB shall take into account • consistency with international standards, • obligations imposed by conventions, • relevant industrial standards, • advances in technology and • possible discrepancies with regulations and guides from other states.
Overview and use of model regulations for the predisposal management of radioactive waste Consultation about Regulations and Guides • New regulatory requirements should be published in draft form for a suitable period of review and comment by licensees and other stakeholders. • Consultation meetings should be held and documented (who attended, when, where, what was discussed and the outcomes of the discussions) • Reports of consultation meetings may be made available to the interested parties, e.g. by posting them on the RB website.
Overview and use of model regulations for the predisposal management of radioactive waste Guidance Documents • Guidance documents give practical advice or recommendations on ways by which the legal requirements of the primary and sub-ordinate legislation can be met. • In some Member States they might be not legally binding. • They are normally issued by the regulatory body to give recommended, generally applicable, detailed operational and technical standards or criteria to ensure that the objectives of the Law and Regulations are achieved. • The Guidance documents are expected to be subject to revision and amendment with changes in the national practice, technical developments, and in the evolution over time of international and national radiation protection standards, goals and policies.

Overview and use of model regulations for the predisposal management of radioactive waste Role and Structure of Regulations Performance regulations: • give general requirements; • specify overall radiation safety requirements and basic operational parameters; • and key objectives to be achieved. • Prescriptive Regulations: • givedetailed requirements; • state how to achieve radiation safety. Most regulations contain both types: • i.e. some are more performanceoriented, other descriptive oriented
Overview and use of model regulations for the predisposal management of radioactive waste Performance Regulations - Example 1. Dose constrains (a) Dose constraints or reference levels will be used when the exposure situation, but not necessarily the exposure itself, usually benefits individuals. (b) Records shall be maintained to demonstrate compliance with this regulation.
Overview and use of model regulations for the predisposal management of radioactive waste Advantages • easy to develop; Performance Regulations (cont) • are focused on objectives: i.e. what should be achieved in terms of protection and safety; • applicable to a range of practices; • easily adapted to evolving circumstances and technology (i.e. do not need to be changed frequently).
Overview and use of model regulations for the predisposal management of radioactive waste Disadvantages • need to be interpreted in relation to each practice; • time and skill is needed from both regulatory staff and the users. Performance Regulations (cont)
Overview and use of model regulations for the predisposal management of radioactive waste Prescriptive Regulations - Examples 2. Dose constraints (1) Dose constraints or reference levels of 1–20 mSv would be used when the exposure situation, but not necessarily the exposure itself, usually benefits individuals. This would be the case, for instance, when establishing dose constraints for occupational exposure in planned exposure situations or reference levels for exposure of a member of the public in existing exposure situations. (2) The records prescribed by the Regulatory Body on dose received by the workers and on the results of monitoring the working place shall be maintained to demonstrate compliance with this regulation.
Overview and use of model regulations for the predisposal management of radioactive waste Prescriptive Regulations Prescriptive Regulations: • define exactly how to achieve adequate dose restrictions; • may define where to conduct workplace monitoring; • may define what type of instruments shall be used; • may define how and what type of records should be maintained; • may be specific to certain types of practices.
Overview and use of model regulations for the predisposal management of radioactive waste Advantages • easy to determine when requirements are met; Prescriptive Regulations (cont) • reduce time and skills necessary to conduct a licensing review or an inspection; • enable authorization and inspection process to focus on simple verification of compliance.
