New Laser-flash Experiments for Irradiated Fuels Under Contrainted Conditions

Abstract

A new group of facilities dedicated to the characterisation of irradiated nuclear fuel under conditions reproducing a variety of in-pile events is being constructed at JRC/ITU. The first planned experiment is the measurement of the local thermophysical properties (local thermal diffusivity, gap condductance)of the fuel. The set-up is used both for steady state and perturbative experiments (heating power variations or other excursions simulating in-pile transients or accidents like RIA).JRC.E.3-Materials researc
