Calculation of Fuel Temperature Coefficient, Reactivity Loss and Temperature of BAEC TRIGA Research Reactor
Keywords:TRIGA Reactor, Fuel temperature coefficient, reactivity loss, Reactor power
AbstractFuel temperature reactivity coefficient is important for reactivity and power excursion transient analysis where power feedback effects depend on the sign, rate and time delay of the fuel temperature reactivity effects. In this study reactivity loss are measured at different fuel temperatures and various reactor power levels. Temperature coefficient of reactivity is measured for BTRR reactor power ranges from 0 to 3 MW. Fuel temperature and water temperature also measured at different reactor power levels. The measured values were found to be within the safety limit as mentioned in the Safety Analysis Report (SAR) of the BTRR. The present study will strengthen reactor operational safety and provide an experimental database for validation of computer codes of the nuclear reactor.
