METHOD FOR PRODUCING LIQUID-FUEL CORE OF NUCLEAR REACTOR Russian patent published in 2005 - IPC

FIELD: nuclear power engineering; nuclear plants for transmutation of radioactive wastes including excess nuclear weapon materials.

SUBSTANCE: proposed method that provides for commencing and ceasing nuclear reaction simply by starting and stopping fuel pumps, effective monitoring and control of nuclear reaction, neutron energy spectrum, and transmutation speed includes production of nuclear-reactor liquid-fuel core by stream of liquid fuel jets formed by means of holes in delivery chamber at core inlet and its discharge to vacant state at core outlet. Core jets are cooled down by means of helium circulating within reactor vessel. Liquid fuel is supplied from liquid state to delivery chamber by means of pumps thereby initiating chain fusion reaction within reactor core. Remaining spaces of liquid fuel loop are always maintained in subcritical state. Stopping liquid fuel pumps causes core disappearance.

EFFECT: facilitated procedure, reduced cost and enhanced safety of radioactive waste transmutation process.
