| Abstract: | The goal of this effort is to propose a novel multiplicative fission and conversion core (MFCC) as a potential heat source or energy provider for a thermal electricity generator. The MFCC is designed to optimize fission and radiative capture reaction rates, promoting the use of conversion of fertile 232Th material as an energy source. The MFCC operates within the 232Th-238U cycle, enabling the continuous conversion of fertile nuclides and sustained fission of fissile nuclide by-products. In the MFCC, neutrons generated by a central fusion source move radially outward, increasing neutron fluency in a subcritical, compartmentalized medium to offset neutron leakage and absorption. Conversion reactions occur in the outer compartment, while a fluid containing extracted fissile nuclides is channeled inward to separate fission compartments, enabling a self-sustaining feed fluid process. The theoretical assessment of heat energy generation was conducted for a set of predefined geometric and material parameters in a simplified matter, demonstrating feasibility. The MFCC may address radiological and environmental challenges inherent in nuclear reactors, improving nuclear safety. [ABSTRACT FROM AUTHOR] |
