Method and apparatus for cementing LIQUID RADIOACTIVE WASTE NPPs and other nuclear power facilities

摘要

1. A method of cementing NPP liquid radioactive wastes and other nuclear facilities, comprising feeding raw LRW means for condensation of the solid phase, removal of the means for thickening the solids the clarified liquid phase to further processing, supplying concentrate from said means for thickening the solid phase into a mixer dosed feeding into the mixer binding additives, mixing the components in a mixer, the direction of the thickened mixture the solid phase from the mixer and the cement in packing and washing with the wash water mixer, of Leach in that the solid phase condensation is conducted in the membrane filter-thickener, and the washing water from the thickener is directed to the mixer together with the original ZHRO.2. An apparatus for cementing liquid radioactive waste nuclear power plant comprising a thickener for thickening solid starting LRW connected in series conduit for moving the concentrate with a mixer, a line for removal of clarified liquid phase to further processing, wherein the mixer is provided with means for dispensing it binder additives supply line in the wash water faucet, characterized in that the thickener is used as a membrane filter, a thickener, a mixer is provided trubop gadfly supplying wash water to the input of the membrane filter sgustitelya.3. A method according to claim 1, characterized in that after the condensation in the solid phase directly thickener filter was washed with water to remove salts present in the liquid waste including borates, with the direction of this permeate formed during the subsequent processing.
