In “the Kola scientific centre of the RAS” (KSC RAS) in August-September will start experiments on new methods of purification of liquid radioactive waste. If the experiments are successful, the development will gradually be implemented in the work of the Kola nuclear power plant and other companies. About this TASS said the doctor of geological-mineralogical Sciences Kola science center of RAS Grigory Ivanyuk.

“Analogues titanosilicate sorbent, synthetic ivancica SIV, which we intend to produce in Russia. In addition, our staff Sergey Britvin first synthesized layered titanate hydrazine with significant regenerative properties, which can bind almost all known radionuclides of strontium and cesium to plutonium and technetium. The first batch of both sorbents and in the form of powders and granules — already made,” said Ivanyuk.

Development allows you to extract radionuclides metals using titanosilicate and titanate sorbents and storing in the composition of titanium ceramic is safer than other ways.

According to the scientist, the currently used technologies do not significantly reduce the volume of liquid radioactive waste, and this complicates their storage. The new methods will help to reduce the amount of 300-1000 times, depending on their initial activity.

“Ceramic granules or even the titanosilicate (titanate) sediment can be buried with less risk than a barrel of liquid waste, or used in the manufacture of batteries for radioisotope sources of energy, but this direction still needs work,” said Ivanyuk.

In the experiment the company “Norilsk Nickel” has allocated 13.5 million rubles. The money will be used for the purchase and installation of equipment.
