Natura Resources
Texas developer of liquid-fuelled molten salt reactors. Its 1 MWt MSR-1 at Abilene Christian University holds an NRC construction permit issued in 2024; the MSR-100 is the 100 MWe commercial design.
Facts
Source per value- DesignThe company's lead reactor design name(s) as the company or its regulator names them; semicolon-separated when it markets more than one.
- MSR-1; MSR-100 1
- TypeReactor coolant/technology family. Gas-cooled fast is separated from thermal HTGR designs; sodium-cooled includes both fast and thermal-spectrum designs.
- Molten salt 3
- Size classDerived from published electric output per module: Micro is 20 MWe or less, Small is above 20 and up to 300 MWe, Medium is above 300 MWe. Legacy heat-only classifications use one third of thermal output as an explicit comparison convention, not a claimed electric rating.
- Small 12
- MWe / module MWeNet (or gross where only gross is published) electric output of one reactor module as the company or its regulator publishes it. Null for heat-only designs.
- 100 12
- MWt / module MWtThermal output of one reactor module as published by the company or its regulator.
- Not published
- FuelFuel form and enrichment class as published (for example LEU UO2, HALEU TRISO, fuel salt).
- Uranium dissolved in fuel salt 23
- Licensing stageFurthest licensing milestone reached with any national regulator: Operating; Construction licensed (construction permit or licence issued); DOE test authorization (a test reactor authorized or built under the US Department of Energy, for example the Reactor Pilot Program or the DOME test bed); Construction under review (construction, site or creation application filed); Design approved (design certification, standard design approval or GDA completed); Design review (formal design review under way, such as UK GDA, CNSC vendor design review or a French safety-options review); Pre-licensing (pre-application engagement only).
- Construction licensed 3
- RegulatorsNational regulators the company has formally engaged (NRC, CNSC, ONR, ASN, and others), semicolon-separated.
- NRC 3
- Licensing detailThe milestones behind the licensing stage, by regulator, with dates.
- NRC issued ACU’s MSR-1 construction permit on 2024-09-16. The 1 MWt research reactor does not generate electricity; the 100 MWe rating belongs to the separate commercial MSR-100 design. 34
- Latest milestoneDate of the milestone that sets the licensing stage (for example the day a construction permit was issued or an application docketed).
- 2024-09-16 3
- First siteLocation of the first-of-a-kind commercial or demonstration unit, with the owner or host.
- Abilene Christian University, Abilene, Texas (MSR-1); Texas A&M RELLIS (MSR-100) 124
- First powerYear the company or its host utility targets for first operation (criticality or commercial operation, as stated) of the first unit. A plan, not a guarantee.
