NEA Expert Group on the Scientific Issues of Fuel Behaviour (TFSFB)
The NEA Expert Group on the Scientific Issues of Fuel Behaviour (TFSFB) deals with the status and trends of scientific issues of fuel behaviour. The aims of the TFSFB are to:- Compile high quality experiments for the International Fuel Performance Experiments (IFPE) database. Emphasis is given to high burn-up in water reactors under normal operating conditions. Priority goes to completed international programmes, the data of which would otherwise be lost, but also to data released from national programmes.
- Co-ordinate the qualification of these data through review and by organising user group meetings. Take initiatives so that it may be adopted as an international standard.
- Co-ordinate computer code validation and benchmark studies.
The expert group organises co-ordination meetings that are held in conjunction with the IFPE database user group meetings every 12-18 months.
The IFPE database will be consolidated during the next three years through updating and addition of new experiments.
Seminars and experts' meetings are held as needed to address high-priority issues for validating the modelling of phenomena of particular concern (thermal performance, fission gas release, pellet-clad interaction, etc.)
The TFSB's work is carried out in co-ordination with the IAEA and the NEA CSNI Working Group on Fuel Safety Margins.
