Senior Expert Group on Safety Research / Support Facilities for Existing and Advanced Reactors 2 (SESAR/SFEAR2)

The Senior Expert Group on Safety Research / Support Facilities for Existing and Advanced Reactors 2 (SESAR/SFEAR2) is responsible for reviewing and updating the previous SESAR assessments of research facilities required to support the safety of nuclear installations. The group shall recommend actions to be taken by the Committee on the Safety of Nuclear Installations (CSNI) and its member countries to facilitate broader use and sustained operation of essential research facilities required to support nuclear safety.

In conducting its review, SESAR/SFEAR2 should ensure that the facilities in all NEA member countries are considered, either through direct representation on the group, or through opportunities for non-group members to provide input. To the extent possible, consideration should also be given to infrastructure of other major nuclear countries like China and India. SESAR/SFEAR2 should interface with groups within the NEA that conduct similar reviews, with the International Atomic Energy Agency (IAEA) and with other international organisations as necessary.

The scope for the SESAR review should first focus on the support required for water-cooled reactors (BWR, PWR, PHWR), particularly those currently deployed in NEA member countries. Nevertheless, recognising the increased importance of innovative reactor designs, requirements for non-water cooled reactors should be included with generic considerations in the various technical areas (e.g. materials, fuel, severe accidents, etc.).

The primary deliverable from SESAR/SFEAR2 should be a concise report that can be used by senior managers to inform and support policy-level decisions on resources and co-operation agreements required to maintain key research facilities. The detailed assessments used to derive the concise recommendations can be published as an addendum that can be used for reference purposes.

The group should develop recommendations within 1 to 1.5 years and the final report should be completed within 2 years.
