✦ Synopsis

The irradiation induced creep in fuel compact materials for R.T.R. applications H. Veringa, R. Blackstone (Reactor Centrum Nederland, Petten, The Netherlands) and R. Liilgen (JRC Euratom Petten N.H., The Netherlands). Restrained shrinkage experiments up to 3 x 102' ncm-* (DNE) in the temperature range of 60&12OO"C on three different dummy coated particle fuel compact materials were performed in the High Flux Reactor at Petten, the Netherlands. The data were evaluated to obtain the steady state irradiation creep coefficient of the compacts. It was found that for the materials investigated, the creep coefficient is temperature dependent, but no clear relationship to the Young's modulus could be established. Under certain conditions, this irradiation induced plasticity influences the elastic properties, while also the creep coefficient increases. This effect coincides with the formation and further opening of cracks due to stresses caused by irradiation shrinkage of the matrix material.
