Abstract

PURPOSE:To make more efficient and safety treatment of nuclear waste possible by adsorbing nuclear waste chemically and physically into an adsorptive red sludge having specific gravity higher than that of sea water and then conditioning the concentration thereof before it is dumped into deep sea. CONSTITUTION:A nuclear waste 1 is admixed, at a weight ratio of 1 (waste)/1000 (red sludge), with an adsorptive alkaline red sludge 2 having specific gravity higher than that of sea water, for example, thus adsorbing the radioactive substance chemically and physically into the red sludge 2. It is then subjected to conditioning of concentration by means of a pH conditioner 3 and dropped slowly through a pipe 5 to a deep sea of about 1000m thence scattered toward the sea bottom of about 10000m depth. This method allows more safe and effective treatment of nuclear waste 1 while reducing the radiation dose thus contributing to environmental protection.
