“…The magnetohydrodynamically driven cooling system, which has neither an impellor nor a sealing part, is operated without contacting the corrosive LBE working fluid. Hence, the reactor operation is inherently safe because of the absence of leakage and corrosion, as has been confirmed . In this respect, a reactor‐integrated magnetohydrodynamic (MHD) coolant circulation system is the most appropriate choice for ensuring the small size, safety, and sustainability of the reactor, not only because it is safe from the corrosiveness of LBE but also because it is structurally simple, high maintenance, and small.…”

“…The stator coils are connected to 3‐phase power to create a magnetic field along the length of the coolant channel. The magnetic field passes through the teeth between the inner and outer cores in the radial direction . The magnetic field traveling along the inner core in the axial direction induces a current in the working fluid according to Ampere's law, where the circumferential‐induced current travels in the passage.…”

“…The magnetic field passes through the teeth between the inner and outer cores in the radial direction. 7 The magnetic field traveling along the inner core in the axial direction induces a current in the working fluid according to Ampere's law, where the circumferential-induced current travels in the passage. Consequently, the LBE coolant is transported by the Lorentz force which is generated in the passage from the vector product of the electric current and magnetic field (J × B).…”

Summary The report describes the development of an innovative magnetohydrodynamic (MHD) space‐integrated coolant system design concept for the small modular lead fast reactor called the ubiquitous, rugged, accident‐forgiving, nonproliferating, and ultralasting sustainer reactor. The coolant system efficiency was analyzed based on space‐integrated geometric and electromagnetic variables related to the circulation of lead‐bismuth eutectic (LBE) liquid metal coolant in a reactor with a thermal output of 100 MWt and using the MHD principle. The objective of the system is to optimize the circulation of the noncontacting liquid metal coolant without any internal structure, such as an impellor or sealing part, to transport the LBE with high electrical conductivity in the reactor. The concept was first applied to the pool‐type integral leading facility for lead‐alloy cooled advanced small modular reactor, which serves as a scaled‐down experimental facility for the ubiquitous, rugged, accident‐forgiving, nonproliferating, and ultralasting sustainer reactor, for characteristic analysis of the coolant system subject to the requirements of a developed pressure of 8456 Pa and a mass flow rate of 21.37 kg/second. The MHD core blanket, which was attached to the upper part of the pool‐type integral leading facility for lead‐alloy cooled advanced small modular reactor and wrapped it cylindrically from the outside to form an annular passage, was designed for the forced circulation of liquid LBE taking into account its internal space and the high operating temperature of 440°C. Design variable analysis provided the optimized geometric and electromagnetic parameters of the MHD driving system based on the electromagnetic characteristics in the coolant passage of the reactor. This forced cooling system concept based on MHD propulsion is structurally simple and will enable significant space reduction and increased power for small modular lead fast reactors. It was also determined that safe long‐term reactor operation could be ensured without requiring particular maintenance because the operation does not involve fluid contact.

“…In this regard, electromagnetic pumps, which are extensively studied, are considered to stably transport the liquid metal coolant. An electromagnetic pump is operated without direct contact with the liquid metal because it does not contain rotating parts such as impellors and seals . During the transportation of liquid metal that has chemical reactivity and is corrosive, changes in properties including decreases in strength or corrosive properties can be caused by the contact between the impeller and liquid metal.…”

Summary One of the most important parts in the development of generation IV nuclear reactors is safety. In the research on generation IV sodium‐cooled fast reactors, magnetohydrodynamic (MHD) circulators have received attention for the stable transport of coolants. In this study, the stability of an MHD circulator was evaluated using a mathematical approach to obtain the critical value of the developed pressure. The critical developed pressure equation is a function of the flow rate and dimensionless parameters, which were derived from the theoretical model of the MHD circulator with a dimensionless scaled velocity, flow rate, and pressure. The stability conditions expressed using the critical value of the developed pressure and dimensionless parameters were investigated according to the changes in the main design variables of the MHD circulator. The relationships between the dimensionless parameters, stability, and main design variables constituting the stability boundary of the MHD circulator were analysed. The stability of the MHD circulator is considered safe when the stability criterion ε is lower than 1. The geometrical variables such as the duct thickness or width of the flow gap and electrical variables such as the frequency were the main parameters affecting the flow stability in the MHD circulator.
