Composition of spent nuclear fuel consists of heavy nuclides and fission products including uranium and plutonium as main actinide. In addition, it is also consist of some minor actinides (MA) which can be recycled to reduce the volume and radioactive intensity of long-lived radioactive waste and in the same time to increase level of proliferation resistance. In general, some MAs can be utilized as useful material such as increasing nuclear fuel production and producing some even mass plutonium such as Pu-238, Pu-240 and Pu-242 as a control material for protected plutonium production. In this paper, identification of even mass plutonium isotopes production for the application of fuel breeding capability and proliferation resistant aspect of isotopic plutonium production was investigated. A large fast breeder reactor (FBR) model is adopted by using 800 days operation for one cycling operation for 4 fuel batches systems for optimization and analyses. The analysis of loading MA materials into the FBR core regions shows the Pu-238 production is increasing significantly as well as additional production of other plutonium isotopes. Isotopic Plutonium production of Pu-238 as main product can be estimated from fuel conversion process of MA in the reactor. This fuel conversion phenomena of Pu-238 can be identified as fertile material for fuel breeding capability, that Pu-238 can be converted to Pu-239 by neutron capture which is similar process also for fuel conversion of Pu-240 to Pu-241 as fissile materials. In addition, isotopic production of Pu-239 from converted Pu-238 as additional fuel which can be added with some quantities of Pu-239 production from converted U-238 for extending reactor operation. Production of Pu-238 in the reactor are used for categorizing some level of protected plutonium productions which can increase isotopic barrier level of plutonium in term of decay heat (DH) as well as Pu-240 as additional even mass contributor.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]FBR,fuel breeding,plutonium production,proliferation resistance,Pu-238,Recycling nuclear fuel[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]We would like to acknowledge and extend our gratitude to Research Program of National Innovative System (NIS/SINAS) ministry for research and technology republic of Indonesia and ITB research activities program for the research grant and publications[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1016/j.egypro.2014.11.868[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
