the technology to evaluate the feasibility of the technology. The members of the
team should work together on R&D and to check whether the data obtained are
sufficient for all members. As a result of this collaboration, it is expected that
sufficient data will be obtained to pursue the next phase of testing and to transfer
the technical knowledge smoothly to other members. Because the engineeringscale test will be conducted by the implementers, education and training of future
operators will be also performed. The team should also evaluate the storage,
transportation, and disposal technology. For this purpose, system engineers who
perform these evaluations should be involved.
28.5 Requirements for Long-Term Knowledge
Management
As already stated, when a nuclear accident occurs there is a much larger volume of
wastes and greater variety of waste types than the conventional wastes generated
from the usual operation and planned decommissioning of a nuclear power unit.
The wastes from a nuclear accident also contain a wider range of concentrations for
the various radionuclides. Consequently, it will take a long period to characterize
the wastes and to carry out the R&D and evaluation of treatment and disposal
technology. It is also expected that the actual treatment and disposal of the wastes
will not take place until after more than a few decades. In consideration of this
waste management period, long-term knowledge management is needed. The
authors propose the formation of an R&D implementation and evaluation team
that will manage and retain technical knowledge. The team should involve younger
staff members, and education and training of the next generation of staff should be
performed by on-the-job training (OJT).
28.6 Conclusion
A significant volume of highly contaminated water was generated from the accidents at the Fukushima Daiichi Nuclear Power Units. Several methods have been
applied to decontaminate the radioactivity of the water, and these methods have
generated various kinds of sludge and spent adsorbents as secondary wastes.
Because long-term waste management is needed, the authors examined a broad
range of issues concerning how to manage these wastes in a safe and efficient
manner. The requirements for an inventory list and online waste management
system; a development strategy for waste treatment, storage, transport, and disposal
technology; formation of an R&D implementation and evaluation team; and longterm knowledge management are proposed.
