Small Modular Reactor (SMR) Regulators' Forum

Small Modular Reactors (SMRs) are advanced reactors that produce electricity of up to 300 MW(e) per module, which is less than current power generation reactors. Many SMRs can be made in factories and transported by truck or rail.

The establishment of regulatory controls for this relatively new type of reactor requires focused and consistent attention. The SMR Regulators’ Forum, created in March 2015, provides support by enabling discussions among Member States and other stakeholders to share SMR regulatory knowledge and experience.

The Forum enhances nuclear safety by identifying and resolving common safety issues that may challenge regulatory reviews associated with SMRs and by facilitating robust and thorough regulatory decisions.

The Forum's work is expected to result in:

  • Positions statements on regulatory issues;
  • Suggestions for revisions to or new IAEA documents;
  • Information to help regulators enhance regulatory frameworks;
  • Reports on regulatory challenges with discussion on paths forward; and
  • Suggestions for changes to international codes and standards.

The Forum was initially created as a pilot project that was conducted from March 2015 to May 2017. That project studied how emergency planning zones and the principles of graded approach and defence-in-depth should be applied to SMRs.

The pilot project resulted in several reports:

In November 2017, Forum members established new working groups  to discuss the following topics:

  • Licensing Issues;
  • Design and Safety Analysis; and
  • Manufacturing, Commissioning and Operations.

Interim reports on those three topics are available :


  1. Employment
  2. Women
