The OECD NEA and IPSN have agreed to jointly organize, from 10 to 21 June 2002,an international accident dosimetry inter-comparison exercise, using a unique facility of this type in Europe: the IPSN research reactor SILENE.
The main objectives are:
a) to validate the performance of accident dosimetry systems through controlled irradiation in a characterised mixed neutron and gamma rays field and
b) to provide the opportunity to validate criticality and particle transport codes used, for example, to assess the dose in the case of an accident and to size facility shields.
The SILENE facility is an experimental reactor built by the IPSN at Valduc, France. It was designed for criticality accidents studies (physics and radiobiology). Runs using 3 different configurations (various neutrons spectra and gamma/neutron ratios) are proposed for the two-week-inter-comparison, furthermore, 2 weeks are needed for the preparation. More than 50 laboratories plan to participate to this inter-comparison.
