Objectives and scope

Under the guidance of the Nuclear Science Committee (NSC) and under the mandate of the Working Party on Scientific Issues of the Fuel Cycle (WPFC), the objective of the Expert Group on Innovative Structural Materials (EGISM) is to conduct joint and comparative studies to support the development, selection and characterisation of innovative structural materials that can be implemented in advanced nuclear fuel cycles, under extreme conditions such as high temperature, high dose rate and corrosive chemical environment and long service lifetime.

Innovative structural materials may comprise, but are not limited to:

The objectives of the expert group are to:


Consistent with the above objectives, the activities of the expert group will include:

1. State-of-the-art assessment of specific areas to be considered as priority areas of research

2. Experimental protocols and standards and share of available experimental installations

3. Common experimental database

Relationships with other bodies

The expert group will liaise closely with other NSC subsidiary bodies, especially the Expert Group on Liquid Metal Technology (EGLM), the Expert Group on Fuel Recycling Chemistry (EGFRC), the Expert Group on Accident-tolerant Fuels for Light-water reactors (EGATFL) and those operating under the guidance of the Working Party of Multi-Scale Modelling for Fuels and Structural Materials for Nuclear Systems (WPMM), in order to ensure the complementarity of their respective programmes of work and to provide advice and support, where required, and undertake common activities, where appropriate. The expert group will collaborate with other international organisations such as the International Atomic Energy Agency (IAEA), European Commission (EC) and the Generation IV International Forum (GIF).


The deliverables of the EGISM will be the following:
