Hence Conductance based Film Thickness Sensor and Film Extraction by sinters & flow rate measurement by novel miniature integral orifice were developed. Experiments carried out in Air-Water Annular Flow Facility successfully. High temp Conductance probe and Film extraction by SS Sinters were commissioned in CHF & Instability Loop for Steam-Water studies. Experiments are in progress.

CHF data was successfully generated in one-sixth sector of AHWR Fuel Cluster at Reactor operating conditions using surface mounted miniature MI thermocouples (T/Cs) technique. The T/Cs were closely spaced near the high quality zone for collecting CHF data. It is observed that CHF occurred at the exit of the T/S. Around 50 CHF data were generated successfully. This measurement helped in obtaining AHWR Critical Power and Thermal Margin.
