ELIMINATION OF FISSION PRODUCTS FROM NUCLEAR REACTORS
Patent
·
OSTI ID:4164867
A method is described for removing fission products from liquid metal fuel reactors. The fuel flows upwards by convection through a vertical tube extending from a highflux reactor core region into an evacuated header, from whence it returns to the core. In the header the fuel presents a free surface. The flow in the tube outside the core is sufficiently small to ensure that the nuclear fission causes boiling of the fuel in the tube and at the free surface, whereby gaseous fission products are removed together with iodine formed by dissociation of metal iodides, and other impurities more volatile than the fuel (e.g., Po from a Bi fuel). The volatile products are eliminated from the header.
