Abstract
In the framework of the European R and D programme on Management and storage of radioactive waste, Task 5 the project Performance assessment of confinement of medium-level and {alpha}-contaminated waste (Pacoma) was carried out. The overall objective of this project is the assessment of the consequences associated with deep disposal of radioactive waste in three types of geological formation. The objective of the present contribution to the Pacoma project is to develop and demonstrate procedures for radiological safety of repositories in salt domes. An analogue study has been performed by the Dutch energy research foundation ECN, where alternative disposal concepts in different salt formations were investigated. In the present report, how far appropriate choice of the repository design parameters can improve the whole system is discussed. The research covers deterministic calculations for three scenarios: the normal evolution scenario with subrosion of the salt dome, the combined brine intrusion scenario with brine intrusion from brine pockets and via an anhydrite vein, and the human intrusion scenario of solution mining of a storage cavern. For the combined brine intrusion scenario alternative waste inventories, different disposal concepts, variants of the layout of dams and sealings are investigated, and results obtained from variations of
