NEUP CINR-19-17183: Mixing of helium with air in reactor cavities following a pipe break in HTGRs

Separate effects tests will be conducted to obtain experimental validation data on mixing of helium and air in reactor building cavities during and after blowdown in HTGRs. Air and helium concentrations, and gas mixture velocity and temperature fields will be measured in simulated reactor cavities. An existing helium flow loop will be used as the source of high pressure/high temperature helium for injection into the cavities and different break configurations will be experimentally investigated.
