Scope
Under the guidance of the Working Party on Scientific Issues and Uncertainty Analysis of Reactor Systems (WPRS), the Expert Group on Reactor Fuel Performance (EGRFP) 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 the International Fuel Performance Experiments (IFPE) database.
Objectives
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 IFPE database.
3. To facilitate the dissemination of technical information and knowledge through activities such as workshops, benchmark studies and training activities.
Working Methods
The EGRFP will report to the Working Party on Scientific Issues and Uncertainty Analysis of Reactor Systems (WPRS) and will meet once per year for plenary meetings, with additional meetings in support of particular activities (e.g. FUMAC, ATF-TS, PCMI benchmark).
Links to other NEA bodies and international projects
The EGRFP will establish links with other bodies working in the area of fuel performance. In particular, the EGRFP will liaise closely with the CSNI Working Group on Fuel Safety (WGFS), the NSC Working Party on Scientific Issues of Advanced Fuel Cycles (WPFC), the NSC Working Party on Multi-scale Modelling of Fuels and Structural Materials for Nuclear Systems (WPMM)1, the WPFC Expert Group on Innovative Fuels (EGIF)2, the WPRS Expert Group on Physics of Reactor Systems (EGPRS) and the Expert Group on Reactor ystems MUlti-Physics (EGMUP). The EGRFP will also establish links with other international activities that are complementary to its work, including the Halden Reactor Project, the Framework for Irradiation Experiments (FIDES) and the IAEA Technical Working Group on Fuel Performance and Technology (TWGFPT).
Deliverables:
Report on experimental data requirements for LWR fuel modelling;
- discussion of data gaps;
- discussion on quantification of data uncertainties and why this is important for fuel performance modelling;Survey of future fuel performance activities and participant interest. Further deliverables to be upon completion of survey.
