Consideration of Treatment and Disposal
of Secondary Wastes Generated from
Treatment of Contaminated Water
Hiromi Tanabe and Kuniyoshi Hoshino
Abstract The earthquake and tsunami on March 11, 2011, caused severe accidents
at the several Fukushima Daiichi Nuclear Power Units, and a significant volume of
highly contaminated water was generated from the accident. Several methods have
been applied to decontaminate the water, including systems from AREVA S.A. and
Kurion, Inc., in addition to the SARRY (Simplified Active Water Retrieval and
Recovery System) and ALPS [Advanced Liquid Processing System; incorporated
in the MRRS (Multi Radionuclide Removal System)] systems from Toshiba Corporation. After the decontamination treatments using these systems, various kinds
of sludge and spent adsorbents were generated as secondary wastes. These wastes
are now tentatively stored at the site, but further treatment shall be applied to
produce appropriate waste forms for interim storage and final disposal in a
repository.
Waste management—the treatment, storage, transportation, and disposal of
these wastes—is believed to require several decades. The authors examined how
to manage these wastes in consideration of the large volume of waste, the variety of
waste types, and the long period required to carry out their treatment and disposal 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; formation of an R&D implementation and evaluation team; and
long-term knowledge management are discussed in this chapter.
