Plenary: Challenges in Clearance
Dr. Joerg Feinhals
CEO at Association for Radiation Protection for Germany and Switzerland. Recently retired
Abstract: Clearance is the most used option to minimize the volume of radioactive waste. German NPPs are using clearance for approx. 97% of the waste generated during decommissioning.
After a historical reflection of the development of clearance regulations, the main future challenges in clearance are discussed. These are among others:
- Personal expertise: We do not have enough well trained experts in clearance for the next decades in Germany, as all German NNPs will be soon shut off and starting dismantling and not enough trained people are available.
- Dose concept for release of sites: Even in EC we have very different national requirements. While Germany is using also the de minimis dose concept for land areas, other countries like Sweden are using different dose concepts for release of sites (e.g. 100 µSv/a).
- Dependency between the national plan for disposal of radioactive waste and clearance regulations. Modifications of clearance regulations can affect the amount of waste very decisively. If the effectiveness for clearance is reduced by modifications of clearance regulations, the planned (or already realized) capacity of national disposal facility can be not enough.
The discussion of these issues underpins the importance of clearance within the next decades.
