“…It is important to match the size of the random speckles such that they take up roughly 5-10 pixels in the image plane to maximize spatial resolution. The research team [40] supporting MRP is currently making use of computer graphics simulations, as shown in Figure 15, to estimate the proper size of the speckle pattern given the MAGNET facility viewport locations that can accommodate the imagers.…”

This report conducts a preliminary investigation of the available literature and summarizes some potential advanced measurement and visualization techniques for operating high-temperature heat pipe (HP) that can be implemented to support the United States (U.S.) Department of Energy (DOE) Microreactor Program (MRP). The primary objective for the extensive literature research is to investigate the possibilities and feasibility for the design and construction of an advanced experimental test facility with the aim of producing high-fidelity high-resolution heat pipe data during its operation.Based on the existing HP test facilities at Idaho National Laboratory (INL)including the Single Primary Heat Extraction and Removal Emulator (SPHERE) and the Microreactor Agile Non-Nuclear Experimental Test Bed (MAGNET)further efforts will be made to examine the technical feasibility to HP measurements and support the research, development, and demonstration (RD&D) process for an HP-cooled microreactor. Continuing collaborations with the Nuclear Energy Advanced Modeling and Simulation (NEAMS) program, other research institutes and universities are considered to be extremely important so that the experimental facility and resultant database can satisfy the validation needs of advanced heat pipe modeling codes being developed under DOE NEAMS program. vii

“…A gas-gap calorimeter was placed in the cooling water loop to measure the heat rejection and determine how much heat was removed from the heat pipe compared with what was being supplied to the cartridge heaters. More information on the assembly and capabilities of SPHERE can be found in previous reports [1,2,27].…”

“…Microreactors with a thermal power output in the range of 0.1 to 20 MW that can be easily assembled in a factory are desired to provide power generation in remote areas [1]. Microreactor concepts generally include passive safety features with the ability to reach high temperatures to increase thermal efficiencies [2,3]. Various reactor coolants are being considered, including flowing He, molten salt, and light-water reactor designs [4].…”

“…Various reactor coolants are being considered, including flowing He, molten salt, and light-water reactor designs [4]. Other microreactor concepts are taking advantage of passive heat removal capabilities using heat pipes, which leverage the boiling and condensing of a molten metal to transport heat from the core to a heat sink, effectively eliminating the need for any forced circulation within the core [2,3].…”

“…Numerous governmental, commercial, and academic institutions from multiple countries aid the deployment of HPMRs. In particular, HPMR development for civilian applications is being spearheaded by the U.S. Department of Energy (DOE) Microreactor Program (MRP) [1,[17][18][19][20][21]. The program involves DOE national laboratories as well as academic and commercial partners and builds on the work which was initiated at Los Alamos National Laboratory (LANL) in the 20 th century [22][23][24][25][26].…”

This internship report presents thermal analysis support aiding the development efforts of advanced reactor systems as a part of the Department of Energy Microreactor Program. The heat pipe microreactor (HPMR) is one such reactor concept where the heat from the reactor core is removed via passively operating heat pipes. Heat pipes have found numerous applications in many fields due to their simplicity, effectiveness, and reliability. The present work includes a review of heat pipe experiments and experimental techniques, ideation on experiments using the SPHERE test bed, identification of heat pipe phenomena of interest, and suggestions for future directions on heat pipe experiments. Hence, it directly supports the development of heat pipe microreactors (HPMRs).
