Abstract:
This study is a survey of the factors of importance for the long term
behaviour of bituminized ion exchange resins. Phenomena occurring in
bituminized waste products affected by the treatment, storage and
disposal are identified. Test methods have been developed for characterizing
product properties, which are important for the long-term
behaviour.
The long-term properties of bituminized ion-exchange resins are studied
in a repository environment with access of water equilibrated
with concrete. In these circumstances the most important properties
are related to the interactions of bituminized waste with the surrounding
barriers. The most important phenomena are water uptake due
to rehydration of the resins and subsequent swelling of the product.
