DesignThe company's lead reactor design name(s) as the company or its regulator names them; semicolon-separated when it markets more than one.: ACP100 (Linglong One) 3
TypeReactor coolant/technology family. Gas-cooled fast is separated from thermal HTGR designs; sodium-cooled includes both fast and thermal-spectrum designs.: LWR 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 3
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 2 3
MWt / module MWtThermal output of one reactor module as published by the company or its regulator.: 385 2 3
FuelFuel form and enrichment class as published (for example LEU UO2, HALEU TRISO, fuel salt).: Not published
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 1 2
RegulatorsNational regulators the company has formally engaged (NRC, CNSC, ONR, ASN, and others), semicolon-separated.: NNSA (China) 1 2
Licensing detailThe milestones behind the licensing stage, by regulator, with dates.: NNSA construction licence No. 2117 was issued on 2021-07-01; construction began 2021-07-13. IAEA PRIS lists the unit as under construction and its first-grid-connection date is null. October 2026 reporting targets fuel loading and grid connection by year-end; no achieved grid date is verified. PRIS gives 100 MWe net and 125 MWe gross. 3 4
Latest milestoneDate of the milestone that sets the licensing stage (for example the day a construction permit was issued or an application docketed).: 2021-07-01 1 2
First siteLocation of the first-of-a-kind commercial or demonstration unit, with the owner or host.: Changjiang nuclear power plant, Hainan 1 3
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.: Not published
OwnershipPublic (listed shares), Private (venture or privately held), Subsidiary (a unit or joint venture of a larger company) or State-owned.: State-owned 2
TickerExchange and ticker of the company or its listed parent.: Not published
ListedFirst trading day of the company's shares (or its listed parent's current ticker) on the exchange named in Ticker.: Not published
FundingHeadline funding: equity raised, public listing, government cost-share awards (DOE ARDP, GAIN, Great British Nuclear and others), with amounts and dates.: Not published
Data-center dealTrue when the company has a signed, announced agreement (PPA, framework, MOU, investment or capacity reservation) with a hyperscaler or data-center operator.: Not published
