A two-phase three-field modeling framework for heat pipe application in nuclear reactors

ABSTRACT This work aims to introduce a new neutrons source technology for research and medical applications, by the conceptualization of the Micro Research Reactor cooled by Heat Pipes (MRR-HP). This is achieved by developing a 3D-detailed neutronics model using the Monte-Carlo Serpent-2.1.31 code, and investigating the neutronics behavior and define the design parameters of the MRR-HP. The MRR-HP is a cylindrical monolithic block (Magnesium-Oxide) that includes; fuel rods (Uranium-Nitride), Dummy Rods (Beryllium-Oxide), Water and Potassium heat pipes for cooling. The monolithic block is surrounded by reflector (Beryllium-Oxide), where moveable reflective bent plates and a cylindrical block are inserted for control/shutdown purposes. The MRR-HP features: 1- Fast neutron spectrum. 2- Compact (1 m diameter, 1.73 m length, mass: 1.982 tons), which permits a high degree of portability and establishment in small facilities. 3- Passive cooling. 4- Operating without refueling/maintenance for ~12.5 years. 5- High-Assay-Low-Enriched-Uranium = 19.75%. 6- Neutron flux ( ). 7- Inherently safe. Based on the obtained results of the neutron flux and spectrum, the MRR-HP is a multi-purpose reactor that has the potential to perform: Boron Neutron Capture Therapy, Neutrons activation analysis, Testing and Calibration, Transmutation, Neutron Imaging, Education and Training, Prompt Gamma Neutrons activation analysis, Isotope Production, Fast Shielding.
