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.
