Objective

As the PAGIS (Performance Assessment of Geological Isolation Systems for Radioactive Waste) /1/ and PACOMA (Performance Assessment of COnfinements for Medium and Alpha Contaminated Waste) /2/ safety studies have indicated, the migration of the critical radionuclides in the Boom clay is one of the key factors in the overall HLW disposal concept in Belgium. For this reason this programme aims at identifying the relevant migration mechanisms and at quantifying the migration parameters for these radionuclides.

This programme, a continuation of ongoing research, involves both percolation/diffusion experiments in the laboratory and in situ (underground lab.).

Work programme:

1. Migration experiments in the laboratory
For a selected list of critical (14C, 99Tc, 135Cs, 237Np) and possibly critical radionuclides (79Se, 93Zr, 107Pd, U-, Am- and Cm-isotopes) as well as for dissolved organic molecules migration experiments in clay cores will be executed.

2. In situ migration experiments
In situ migration tests with HTO (tritiated water) and 134Cs were started previously and are regularly monitored.
Additional tests with Am, Tc and HTO are planned.
