Abstract

The effects of radiation on the properties of intermediate level waste forms relevant to their storage and disposal have been determined as part of a wider programme of characterisation of low and intermediate level waste forms initiated by the CEC. The aims of this work were to provide immediate data on the effects of radiation on important European intermediate level waste forms through accelerated laboratory tests, and to develop an understanding of the degradation processes so that long-term effects at low dose rates can be predicted with confidence from short-term experiments at high dose rates. The main findings obtained are summarised. The programme included cement waste forms containing inorganic wastes, organic matrix waste forms and cement waste forms containing a substantial component of organic waste. Irradiations were carried out by external gamma sources and by the incorporation of alpha emitters, such as 238Pu. Irradiated materials included matrix materials, simulated waste forms and real waste forms.
