High-Assay Low-Enriched Uranium (HALEU) is a concentrated nuclear fuel physically required to power next-generation modular reactors, produced by spinning uranium gas through thousands of centrifuges to isolate specific combustible isotopes just below the legal threshold of weapons-grade material.
A molten salt pump is a heavily shielded, extreme-temperature mechanical circulator that forces highly corrosive, radioactive liquid fluoride salts through a nuclear reactor core to transfer heat without requiring high-pressure containment vessels.
A TRISO particle is a poppy-seed-sized unit of uranium encased in multiple layers of engineered carbon and ceramic that physically cannot melt or release radiation under any known commercial nuclear reactor failure condition.
