Description
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 backfill material and EDZ. It is expected that significant contamination or oil spills can be detected and remedied, so that only a very small fraction of the backfill material and EDZ would be affected. This is not considered any further (negligible effect).
