Scope

Under the guidance of the Working Party on Scientific Issues of Reactor Systems (WPRS), the Expert Group will perform specific tasks associated with fuel performance aspects of present and future nuclear power systems, with a focus on normal operating conditions. Reactor types considered include, but are not limited to, the following:

Focus is on LWRs for modelling, all systems for inclusion of data within IFPE.

Objectives:

  1. To provide expert advice to the WPRS and the nuclear community on the development needs (data and methods, validation experiments, scenario studies) for existing and proposed fuel designs. A key activity associated with this objective is the identification and preservation of appropriate experimental data.
  2. To provide specific technical information regarding:

This technical information will generally be derived from a combination of direct experimental evidence and/or the results of theoretical benchmark analyses using accurate, validated modelling methods. In either case the availability of suitable experimental data is a fundamental requirement. A key objective of the group will therefore be to help identify, evaluate and preserve this type of experimental data. In this context the Expert Group will monitor, steer and support the continued development of the International Fuel Performance Experiments (IFPE) Database.

3. To facilitate the dissemination of technical information and knowledge through activities such as workshops, benchmark studies and training activities.

Links to other NEA bodies and international projects

The Expert Group will establish links with other bodies working in the area of Fuel Performance. In particular the Expert Group will liaise closely with the CSNI Working Group on Fuel Safety (WGFS), the NSC Working Party on Scientific Issues of the Fuel Cycle (WPFC), the NSC Working Party on Multi-scale Modelling (WPMM), the NSC Expert Group on Accident Tolerant Fuels for LWRs (EGATFL), the Expert Group on Innovative Fuels (EGIF), the Expert Group on Multi-Physics, Experimental Data, Benchmarking and validation (EGMPEBV) and the WPRS Expert Group on Uncertainty Analysis in Modelling (EGUAM). The Expert Group will also establish links with other international activities that are complementary to the work of the EGRFP, including the Halden Reactor Project and the IAEA Technical Working Group on Water Reactor Fuel Performance and Technology (TWGFPT).

Deliverables:

Meeting frequency:

Once per year for full experts group with additional meetings in support of particular activities (e.g. FUMAC, PCMI benchmark).
