| Abstract: | The aim of calculations is to evaluate the evolution of the infinate multiplication factor (k{sub inf}) during the irradiation of minor actinides, High Level Waste (HLWL) and Plutonium. The most important results are independently verified with Monte Carlo calculations. The relative importance of the main parameters affecting the k{sub inf} was investigated by performing calculations with several minor actinide and plutonium concentrations as well as different ²³⁸U decontamination factors for HLW. The merit figure value for minor actinide alone, considering a constant neutron flux indicates that the best results are reached for minor actinide concentration equal to PWR spent fuel. The best plutonium burning results are obtained for a concentration (50.23 g/l) equal to the half of PWR spent fuel one. The simulations lead to two different reactor concepts: one for HLW burning and the other for plutonium burning purposes. To burn the HLW the most suitable reactor is an homogeneous one. This kind of reactor can effectively be utilised to burn minor actinide in low concentration (namely the PWR spent fuel). On the other hand an heterogeneous reactor with channels filled by all actinides present in PWR spent fuel with the exclusion of U isotopes with a concentration of 50 g/l can be studied. |
