Safety evaluation of geological disposal concepts for low and medium-level wastes in rock-salt (Pacoma project)
In the framework of the Performance Assessment of Confinements for MLW and Alpha Waste (PACOMA), the disposal options dealing with rock-salt were studied. The overall objectives of these studies were to develop and demonstrate procedures for the radiological safety assessment of a deep repository in salt formations. An essential objective was to show how far appropriate choices of the repository design parameters can improve the performance of the whole system. The research covers two waste inventories (the Dutch OPLA and the PACOMA reference inventory), two disposal techniques (conventional and solution mining) and three types of formations (salt dome, pillow and bedded salt). The methodology used in the consequence analysis was deterministic. The models and calculation tools used to perform the consequence analysis were the codes EMOS, METROPOL and BIOS. The results are expressed in terms of dose rates and doses to individuals as well as to groups. Detailed information with respect to the input data and the results obtained with the three codes are presented in the three annexes.
