Abstract

Before radioactive waste packages can be accepted for disposal, low rates of gas release from waste products have to be guaranteed to minimize the release of radioactive and/or chemically-reactive gases into the environment or the atmosphere of a repository. The following issues have been investigated:

- The validity of the average gas formation rate estimated by a single gas analysis at room temperature with respect to gas release in the repository;
- The possibilities of determining the gas release rate for extremely loose packages;
- The decision criteria for the subsequent treatment of packages to minimize gas release in a repository.

In addition, a device for technical in-drum hydrogen absorption has been developed to reduce pressure build-up. Gas formation rates in radioactive and non-radioactive waste drums and containers filled with pellets of various compositions were determined in long-term tests. The influence of temperature on gas production was also evaluated by heating the waste packages from room to repository temperature. ture.
