Technical Working Group on Small and Medium Sized or Modular Reactors (TWG-SMR)

Background

The IAEA Technical Working Group on Small and Medium Sized or Modular Reactors (TWG-SMR) is an advisory group of high-level experts from Member States with interest in the development and future deployment of SMRs.

The TWG-SMR was established in 2018 to provide advice, recommendations and support to the IAEA for the programmatic planning and implementation related to technology development, design deployment and economics of SMRs that can be used for the production of electricity and/or industrial process heat in both expanding and embarking countries.

The members of the TWG-SMR are appointed by the IAEA Deputy Director General and Head of the Department of Nuclear Energy for a fixed term of four years, following consultation with the respective national authorities and organizations.

Scope

The TWG-SMR focuses on technology development, design, deployment and economics of SMRs that can be used for the production of electricity and/or industrial process heat in both expanding and embarking countries. The Technical Working Group will provide advice, recommendations and formulate programmatic guidance for the IAEA’s activities on SMRs, specifically in the following areas:

  • Research, technology development and innovation;
  • Development of generic technical requirements for user countries;
  • Technology assessment approaches for advanced SMR designs;
  • Reliability, safeguardability, and constructability;
  • Codes and design standardization of structures, systems and components;
  • Industrialization of SMRs, covering design, engineering, manufacturing and supply chain;
  • Site characterization;
  • Economic competitiveness, financial considerations, market needs and cost analysis;
  • Capacity building for embarking and expanding nuclear countries;
  • International cooperation.

Functions

Functions of the TWG-SMR are:

  • a) To provide advice and guidance, and to marshal support in interested Member States for implementation of the IAEA’s programmatic activities on technology development, design, deployment and economics of SMRs for the production of electricity and/or industrial process heat (the Technical Working Group will also provide guidance on developing roadmaps to assess the technology readiness level of SMR designs for deployment in Member States);
  • b) To provide a forum for information and knowledge sharing on national and international programmes in the area of SMR technology development, deployment and human capacity building;
  • c) To act as a link between the IAEA’s activities in specific areas and national technical and industrial communities, as well as delivering information from and to national communities;
  • d) To provide advice on preparatory technical missions in Member States, on the IAEA’s activities in planning and implementing coordinated research programmes, collaborative assessments and other activities, as well as on the review of the results of SMR demonstration projects;
  • e) To develop and/or review selected IAEA publications from the IAEA Nuclear Energy Series or the IAEA Technical Documents series, assess existing gaps and advise on the preparation of new publications or other outputs;
  • f) To identify important topics for discussion by the Standing Advisory Group on Nuclear Energy (SAGNE) and contribute to status reports, Technical Meetings and topical conferences in the field of advanced SMRs and their applications;
  • g) To encourage the participation of young nuclear professionals, in particular from embarking countries, as appropriate, in IAEA activities.

Membership

Members of the TWG-SMR shall be appointed by the Deputy Director General, Head of the Department of Nuclear Energy, following consultation with the respective national authorities or organizations.
