Rosenergoatom's press service said the plant, designed for the reprocessing of liquid radioactive waste from region's Kola nuclear power plant (NPP), went on stream following nine years of construction and six months of operating tests.
Company head Sergei Obozov said no other country has the new technology to be used at the facility, adding that it was developed by Russian experts.
The company said earlier the new technology allows for purifying nuclear water at a higher degree, resulting in a considerable reduction of radioactive waste.
Liquid radioactive waste from the almost-full storage facilities at the Kola NPP will be treated by converting it into a solid form, which is more convenient for all stages of handling -- storage for 300-500 years, shipment and final disposal.
"Liquid radioactive waste will be passed through special filters to accumulate all radioactive substances, mainly cesium and cobalt," he said. "As a result, the volume of radioactive waste will be reduced some 100-fold."
State-run Rosenergoatom runs a total of 31 power-generating units at 10 of Russia's nuclear power plants.
