Founded in 2020, Abilene, Texas-based Natura Resources has quickly become a governmentally recognized advanced nuclear reactor developer. In 2023, the company built the Science and Engineering Research Center (SERC) at ACU, the first advanced reactor research facility outside a national lab in the US.
The company uses liquid-fueled molten salt reactor (LF-MSR) technology, allowing molten salts to act as fuel and a coolant. According to its website, a mixture of lithium fluoride (LiF) and beryllium fluoride (BeF2) salts or thorium fluoride (ThF4) salts can be used, which allows the reactor to operate at temperatures higher than solid-fuel reactors.
Since the fuel also works as a coolant, it is removed continuously from the reactor for fissile material to be replaced. This process also makes MSR reactors meltdown safe.
