The decommissioning of nuclear power stations will lead to the production of a
number of contaminated components. The materials produced will consist of process
and structural wasteforms. Before this waste can be disposed it will be necessary to
obtain a full inventory of those radionuclides contained in those wastes. This will be
necessary to ensure that the waste is handled in a suitable manner and that full
information is available so that reliable risk assessment can be carried out on the
proposed disposal site.
A number of radionuclides have been highlighted as significant in terms if their halflife,
terrestrial mobility and predicted levels in decommissioning wastes.
A selection of these radionuclides have been investigated, and methods developed
for their determination in concrete.
It was a requirement of this work that the methods developed were robust and that
the minimum detectable amount was below that of the de minimis of O.4Bq g-1.
