Abstract
An installation is for the destruction of radioactive metallic sodium and includes a reaction vessel containing an aqueous solution, the reaction vessel having an aqueous solution outlet; a sodium feed circuit configured for feeding liquid metallic sodium into the reaction vessel; a liquid effluent treatment unit, comprising a drain tank and a drain line fluidically connecting the aqueous solution outlet to the drain tank; a gas treatment unit configured for diluting the gases and releasing the diluted gases into the atmosphere, the drain tank having a gas outlet fluidically connected to the gas treatment unit; an inert gas feed unit configured for feeding the drain tank.
Claims10
A radioactive metal sodium destruction installation comprising:
- a reaction vessel containing an aqueous solution, the reaction vessel having an aqueous solution outlet;
- a sodium feed circuit configured for feeding liquid metallic sodium into the reaction vessel;
- a liquid effluent treatment unit comprising a drain tank and a drain line fluidically connecting the aqueous solution outlet to the drain tank;
- a gas treatment unit configured for diluting gases and releasing the diluted gases into the atmosphere, the drain tank having a gas outlet fluidically connected to the gas treatment unit;
- and
- an inert gas feed unit configured for feeding an inert gas into the drain tank.
A process for destruction of sodium in a fast-neutron nuclear reactor, the process comprising:
- feeding liquid metallic sodium into a reaction vessel containing an aqueous solution, the reaction vessel having an aqueous solution outlet;
- collecting the aqueous solution from the reaction vessel in a drain tank, the aqueous solution flowing through a drain line from the aqueous solution outlet right to the drain tank;
- feeding an inert gas into the drain tank;
- and
- diluting the gases coming from the drain tank, and releasing the diluted gases into the atmosphere.
