Reserach and development on geological
disposal |
Technical development of engineered barriers
suitable for geological environment is conducted based
on geoscientific research results. Research on detailed
designing methods of disposal system and tests for confirmation
of safety assessment methods are also conducted in shafts
and drifts. Tasks
> Verification of engineering technology for
engineered barriers, etc.
> Confirmation of applicability of design method
> Confirmation of applicability of safety assessment method |
Verification of engineering
technology for engineered barriers etc.
Research and development is conducted to assess the accuracy required for engineered
barrier placement equipment. Research and development is also conducted on technology
of backfilling shafts and drifts. |
Confirmation of applicability
of design method
Research and development is conducted in designing the entire disposal system,
including geological formations in which the waste is to be emplaced.
|
Confirmation of applicability
of safety assessment method
Items, quantities and accuracy of geological environment
data necessary for safety assessment of geological disposal
are confirmed by conducting applicability test and improving
models used for safety assessment. |
