Abstract
The TRIGA research reactor ex-core nuclear instrumentation provides information on the reactor thermal power level, which is essential for the safe operation of the facility. In addition, exact knowledge of the reactor power level is necessary for the analysis of experiments and the normalization of reactor calculations. At the Jožef Stefan Institute TRIGA Mark II reactor the instrumentation is periodically calibrated using the calorimetric method. Though relatively simple and reliable it can be burdened with up to 30% uncertainty. In the paper a new calibration procedure using electrical heaters is presented, with which the heat capacity constant of the reactor pool is calculated to be C = 19.6 kWh/K ± 0.3 kWh/K and the uncertainty of the thermal power value is significantly reduced to approximately 2%.
