What is deep borehole disposal?
In our research project:
disposal of high-level radioactive waste in 5000 m deep vertical
boreholes
waste disposal zone from 3000 m – 5000 m depth
waste disposal zone: crystalline basement rock
overburden: layers of salt and/or clay
sealing zone from 3000 m – 0 m (surface)
Advantages of a deep borehole disposal:
great distance between the waste canisters and the biosphere
long sealing zone up to 3000 m
low permeability, high salinity and reducing conditions in the host rock
possibility of several different overlaying layers like clay and salt

sealing of the borehole in a fluid (materials, technology, …)
concept for the storage on basis of known waste inventory
(size and number of waste canisters, number of boreholes)
Evaluation of the deep borehole disposal option by showing
the chances and the risks

Summary (1)
The deep borehole disposal option still has some severe
challenges to deal with and will require research and
development work in several areas.
Outgoing from the current state of the art in drilling techno-
logy it will not be possible to create a repository with a
realistic number of deep boreholes in that we could dispose
all of the high-level radioactive waste of Germany because
standard equipment from oil and gas industry is not suited
for repositories of high-level radioactive waste.

Summary (2)
There are still some unsolved problems that might never be
solved specifically the issue of retrievability, which is
demanded in Germany.
By solving the uncertainty of retrievability and with further
research especially in drilling technology (development of
required technology appears feasible - provided there will be
a “market” for the service companies), the deep borehole
disposal option could be an alternative for the future.
