Abstract: The results of the measurement obtained revealed that the coolant temperature difference is approximately uniform over the period of operation with an average value of 12.1°C for experiments performed at half power and 19.5°C for operation at full power. The average core temperature of the reactor was found to have mean values of 19.8°C and 44.3°C at half and full power levels respectively. The average value for the predicted power of the reactor at half and full flux was found to be 14.9 kW and 31.30 kW respectively. The variation of the inlet temperature (Tin) and coolant temperature (ΔT) with the reactor power was also investigated and the results show that the thermo-hydraulic parameters dictate the power level but have no significant influence on power excursion, coolant boiling and radiation exposure of personnel.
