The nature of long-lived radioactive wastes is that
they present a radiological hazard over a period
of time that is extremely long compared with the
timescale over which the engineered protection
systems and institutional management of a disposal, or
long-term storage, facility can be guaranteed. Safety
assessments for potential deep repositories need
to be able to provide indicators of safety performance
over time periods of hundreds of thousands of years.
On such timescales, it is generally assumed that
radionuclides may be slowly released from the
containment system, migrating via geosphere pathways
until they reach the accessible environment. Hence,
there is a need to study the evolution of the
environment external to the disposal system and the
ways in which this might impact on its long-term
radiological safety performance, for example in terms
of influences on the migration and accumulation of
