Radioactive waste piles up at Fukushima nuclear plant as disposal method remains in limbo, Mainichi, October 3, 2011:
[... A]t the crippled Fukushima No. 1 Nuclear Power Plant, high-level radioactive waste has kept piling up amid no clear indications of its final disposal destination.
[...] 4,700 drums of radioactive waste after three months of cesium decontamination [...]
TEPCO has been unable to fully grasp the details such as the types and the concentration of nuclear materials.
Professor Akio Koyama at Kyoto University Research Reactor Institute says, “The density of high-level decontaminated water is believed to be a maximum 10 billion becquerels per liter, but if it is condensed to polluted sludge and zeolites, its density sometimes increases by 10,000 times [100 trillion Bq/L]. The density cannot be dealt with through conventional systems.”
