CHEMICAL REACTOR FOR PROCESSING RADIOACTIVE ALKALI METAL Russian patent published in 2015 - IPC G21G4/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a chemical reactor for processing a radioactive alkali metal. The disclosed apparatus includes a reactor housing (5), the inside of which is divided by a gas-permeable partition wall (2) into a lower chamber (8) and an upper chamber (1). The lower chamber is provided with a pipe for feeding a gas reagent (14); the upper chamber is provided with a pipe for feeding a molten alkali metal (15). The disclosed apparatus has a jacket (11) for cooling the reactor housing. A baffle plate for the jet of alkali metal (9) and a connection pipe (10) with a sliding valve (16) are placed opposite the pipe for feeding molten alkali metal (15) in the upper part of the upper chamber (1) with spacing from the pipe. In special cases of the chemical reactor, a louvered grille (3) with a variable louver tilting angle is placed under the baffle plate for the jet of alkali metal. The baffle plate for the jet of alkali metal can be provided with an electric drive and can also be connected to an ultrasonic generator. The slide valve can be provided with an electric drive. The chemical reactor can also include a shut-off valve (4), a manometer (6), a pressure pipe (7) for the cooling liquid, a discharge pipe (13) for exhaust ventilation.

EFFECT: enabling periodic processing of an alkali metal while preventing escape of radioactive particles.
