The ultimate water treatment system

摘要

Efforts to restart emergency diesel generators at the Fukushima Daiichi nuclear power plant were foiled early last year by the discovery of huge amounts of highly contaminated water flooding the basements of site buildings. Over the following months, TEPCO developed and built temporary systems for water decontamination, which started up in June 2011. Initially the temporary water treatment system used a decontamination system from AREVA (see also NEI June 2011, pl7) and was later supplemented by one, and then two, lines of a Toshiba SARRY decontamination system. Both systems incorporated adsorption towers with ionexchange resins to grab and immobilise radionuclides present in the water.
