The research designs a fuel cell based on Natural Uranium Metal (U-10%wtZr) with the addition of minor actinide such as Am-241, Np-237 and Cm-244. The coolant used is Helium and the cladding is Stainless Steel (SS316). This fuel cell is pin shaped with a diameter of 1,4 cm. The fuel cell was tested with 5% enrichment without minor actinide and then minor actinide was added alternately. Calculat…
