VVER-1000 fuel cycles analysis with different burnable absorbers

Popis výsledku v původním jazyce

The increase of fuel cycle efficiency is crucial for all reactor operators. Burnable absorbers can compensate excess reactivity at the beginning of the cycle. They also stabilize the power distribution. The commonly used burnable absorbers are in form of Gd2O3 and IFBA in LWR. Also interest in Er2O3 has been rising during recent years. New strategies of operation with focus on very long cycles or new projects like Small Modular Reactors are moving development towards reactor cores that have to allow achieving self sustainable chain reaction for much longer. This shift to the very long operation increases demand for new types of burnable absorbers. Burnable absorbers covered in this study are gadolinium, erbium, cadmium, indium, iridium, and lithium. These materials were tested via physics model of VVER-1000 reactor. Fuel characteristics were calculated at the lattice level of an individual fuel assembly. Secondly, the full core characteristic were evaluated.
