A RADIATION DECONTAMINATION TECHNOLOGY WITH THE IN-VEHICLE WATER TREATMENTSYSTEM
M.Tsubaki, and K.Shibano
It collected while making the sediment with which the fire prevention water tank, the pool, and the regulating reservoir, etc.
were polluted by the in-vehicle type water processor circulate, the technology to purify water was developed, it was adopted
for the Fukushima Prefecture decontamination technology proof business in 2012 fiscal year, and decontamination was fieldtested in the fire prevention water tank of the Fukushima city. The problem was caused from the test outcome for the stirmethod in the fire prevention water tank and the method of dehydrating the waste sludge. It was adopted for the Fukushima
Prefecture decontamination technology proof business again to solve such a problem in 2013 fiscal year, and it field-tested it.
It reports on the result of the decontamination field test in this report. The field test of the method of especially stirring thebottom sediment and the technology of the method of dehydrating the waste sludge was executed in this examination. The
following results were obtained from the field test.
