International Fuel Performance Experiments (IFPE) is the public domain database on nuclear fuel performance experiments for the purpose of code development and validation
The aim of the project is to provide a comprehensive and well-qualified database on Zr clad UO2 fuel for model development and code validation in the public domain. The data encompasses both normal and off-normal operation and include prototypic commercial irradiations as well as experiments performed in Material Testing Reactors. This work is carried out in close co-operation and co-ordination between OECD/NEA, the IAEA and the NEA Halden Reactor Project.
Acquisition of data through discussion and negotiation with originators;
Compilation of the data into a standard form and content as agreed by an expert group set up to supervise the work;
Peer review of the data by independent experts;
Integration and indexing of the data into the IFPE database, inclusion of all used reports in electronic form;
Distribution to interested parties and assistance where necessary in use of datasets.
Content of the IFPE database
The database is restricted to thermal reactor fuel performance, principally with standard product Zircaloy clad UO2 fuel, although the addition of advanced products with fuel and clad variants is not ruled out. Emphasis has been placed on including well-qualified data that illustrate specific aspects of fuel performance. Of particular interest to fuel modellers are data on: fuel temperatures, fission gas release (FGR), fuel swelling, clad deformation (e.g. creep-down, ridging) and mechanical interactions. Data on these issues are of great value if measured in-pile by dedicated instrumentation and in this respect, the IFPE Database is fortunate in having access to several diverse experiments. In addition to direct in-pile measurement, every effort is made to include PIE information on clad diameters, oxide thickness, hydrogen content, fuel grain size, porosity, Electron Probe Micro Analysis (EPMA) and X-ray Fluorescence (XRF) measurements on caesium, xenon, other fission product and actinides.
To date about 1452 rods/samples from various sources encompassing BWR, CAGR, PHWR, PWR, and VVER reactor systems have been included. The full list of data is available on the dedicated webpage.
