The IMSR belongs to the denatured molten salt reactor (DMSR) [7] class of molten salt reactors (MSR). It is designed to have all the safety features associated with the Molten Salt class of reactors including low pressure operation (the reactor and primary coolant is operated near normal atmospheric pressure), the inability to lose primary ...
The denatured molten-salt reactor (DMSR) was an Oak Ridge theoretical design that was never built. Engel et al. 1980 said the project "examined the conceptual feasibility of a molten-salt power reactor fueled with denatured uranium-235 (i.e. with low-enriched uranium) and operated with a minimum of chemical processing."
Passive decay heat cooling. Many reactor designs (such as that of the Molten-Salt Reactor Experiment) allow the fuel/coolant mixture to escape to a drain tank, when the reactor is not running (see "Fail safe core" below). This tank is planned to have some kind (details are still open) of passive decay heat removal, thus relying on physical ...
Molten salts (fluoride, chloride, and nitrate) can be used as heat transfer fluids as well as for thermal storage. This thermal storage is used in concentrated solar power plants. [8] [9] Molten-salt reactors are a type of nuclear reactor that uses molten salt(s) as a coolant or as a solvent in which the fissile material is dissolved ...
The multidimensional component in RELAP5-3D was developed to allow the user to accurately model the multidimensional flow behavior that can be exhibited in any component or region of a nuclear reactor coolant system. There is also two dimensional conductive and radiative heat transfer capability and modeling of plant trips and control systems. [10]
A sample of thorium. Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium.A thorium fuel cycle can offer several potential advantages over a uranium fuel cycle [Note 1] —including the much greater abundance of thorium found on Earth, superior physical and nuclear fuel properties, and reduced ...
The U.S. Nuclear Regulatory Commission is issuing a construction permit for a new type of nuclear reactor that uses molten salt to cool the reactor core. The NRC is issuing the permit to Kairos ...
The fuel salt circulates from the reactor to the primary fuel pump, then the Primary Heat Exchanger (PHX), where it then flows back into the reactor. The primary fuel loop is a forced flow loop system. The components that are part of the primary fuel loop are the reactor, PHXs, pump bowl, pump, and hot and cold leg piping.
