Description
The source of the bentonite will be carefully selected and quality checked. Oil-spills in the tunnel could be a potential source of localised contamination. The effect could be a reduction in sorption of radionuclides in the bentonite buffer. It is expected that significant contamination or oil-spills can be detected and remedied, so that only a very small fraction of the bentonite would be affected.
