NUCLEAR SOLVENT REACTOR Russian patent published in 2017 - IPC G21C1/24 

FIELD: chemistry.

SUBSTANCE: reactor includes a housing filled with a solution of a fissile material, for example, uranyl sulfate. Cooling of the solution is ensured by a serpentine-type condenser immersed in it, through which cooling water is pumped from the external circuit. The radiolytic hydrogen and oxygen formed in the solution in the vapour-gas mixture are pumped through the catalyst, recombined, and the recombination product - water vapour - returns to the reactor in the form of water after cooling, which maintains the material balance of the active zone. The isolation of medical isotopes is made from the solution by selecting it. The work of the claimed device under vacuum in a gas cushion is envisaged, which excludes the release of radioactive products from the housing and the recombination system in the event of a leakage loss, as well as a low hydrogen concentration in the vapour-gas mixture, which excludes the possibility of an explosion. Forced circulation of the solution within the reactor vessel and forced pumping of the vapour-gas mixture along the catalytic recombination circuit are also envisaged.

EFFECT: increasing the reactor capacity while maintaining high safety conditions due to lower temperature and partial pressure of water vapour, the possibility of increasing the volumetric flow rate of the vapour-gas mixture and the corresponding decrease in the hydrogen concentration.
