Abstrak/Abstract Current thermal nuclear reactors mostly utilize uranium (235U) as the fuel to allow for fission chain reaction and to eventually produce power. This decreases the amount of uranium in earth overtime. The search for the substitute fuel material is a rising research topic recently. Some considered Thorium (232Th) due to its major advantage in low void coefficient [1, 2]. 232Th also has the potential to breed into 233U, which is a fissile fuel. Th is reported to be three to four times more abundant in nature than U, based on its average concentration in the earth’s crust [3]. Implementation of Th as the fertile fuel is studied in Reduced Moderation Pressurized Water Reactor (RMPWR). Th is incorporated with other materials in the fuel, which include transuranic (TRU) materials that come from the current power plant spent fuels [4]. The reduced moderation allows for harder neutron spectrum to burn the transuranic and are expected to breed 233U from the 232Th. The breeding potential of RMPWR is expected to extend the fuel cycle length to a certain time. Cycle length is the operational duration before a reactor need refueling. This study assesses the breeding potential of 3-dimensional (3-D) RMPWR fuel assembly (FA) for various fissile enrichments and pitch lengths.
