Pulsing Analysis of TRIGA Burn Core using PARET/ANL

Öz

A transient-state thermal hydraulics analysis of the TRIGA burn core of the TRIGA Mark II research reactor has been conducted using PARET/ANL. This study covers the calculation of safety parameters due to large reactivity insertions at low operating power. The peak power and energy for the burn core have been calculated, whose values were found to be lower than those of the beginning of the cycle (BOC) core. Moreover, the safety parameters of DNBR and clad temperature maintain well margins with the Safety Analysis Report. No nucleate boiling was observed in the hottest fuel. Hence, the burn core can be safely utilized for pulsing operation.
