Salt loop
The loop connects core power, heat exchangers, cleanup, and storage-ready thermal delivery.
Open pageMSBR architecture
Liquid fuel, chemistry, moderation, and heat delivery as one system.
The technology stack centers on a circulating fuel salt that carries heat out of a graphite-moderated core while online systems manage chemistry and fission products.

Four linked engineering domains
MSBR design is not a single component story. The reactor, cleanup systems, heat exchangers, storage, and customer heat island have to be designed as one operating plant.

Architecture choices
The design thesis is to make the salt loop the economic center of the plant. That means prioritizing reliable heat transfer, maintainable chemistry systems, and a core arrangement that preserves neutron economy.
Liquid fuelFissile and fertile material are dissolved in fuel salt rather than locked inside batch-fabricated assemblies.
Thermal spectrumGraphite moderation supports the neutron economy needed for the thorium-to-U-233 pathway.
Online cleanupGas stripping and chemistry control reduce poison buildup and help keep the salt inside its operating band.
Heat islandHigh-temperature heat can serve industry directly before power conversion is considered.
Next: fuel salt loop
The fuel salt loop is where the MSBR stops looking like a conventional reactor and starts looking like a high-temperature chemical plant.
