SSC RF-IPPE developed technical project of experimental reactor facility cooled with evaporating liquid metals at 1988-97. Evaporating sodium used as a coolant of the core of facility. As a coolant for second loop evaporating sodium-potassium eutectic alloy used. The third loop fulfilled with gas – working fluid of Sterling or Bryton cycle. Nuclear and thermo-hydraulic calculations performed for nuclear facility1.2 Mw of heat. Many thermo-hydraulic experiments with single-element, three-element and seven-element electrical imitators of fuel roads performed.
So, calculated parameters of core elements validated. Two fuel roads cooled with evaporating sodium tested in nuclear fast reactor.
Three-loops sector mock up including 72 imitators of fuel roads created and tested as well. It corresponds to 1/6 part of the core. Beside it, the mock up includes imitators of neutron reflector, shield and natural size dome. Outside of the dome interlope heat exchanger and the third lope of the facility replaced. Many thermo-hydraulic experiments performed but not finished, unfortunately.
