“Copenhagen Atomics’ 11.000 m2 reactor production facility in southern Copenhagen. Fixed price per reactor unit Each thorium molten salt reactor unit is priced at $50M, all-in, no overruns.”
“Copenhagen Atomics is a Danish nuclear energy company building thorium molten salt reactors for mass manufacturing. Founded in 2014 and based near Copenhagen Airport, the company has 75 engineers, has built two prototype reactors, and targets electricity at below $20 per MWh. The first 1 MWth test reactor is expected to be operational by 2028.”
“A molten salt reactor (MSR) uses liquid salt as both the fuel carrier and the coolant, instead of solid fuel rods and pressurised water. The reactor operates at atmospheric pressure, which removes the risk of a pressurised steam explosion. Higher operating temperatures also make the energy conversion more efficient than conventional light water reactors.”
“The first 1 MWth test reactor is planned to be operational by 2028. Commercial reactors producing 100 MWth per unit are planned for the early 2030s. Copenhagen Atomics has already completed two prototype reactors and expects to complete a third in 2026.”
“Copenhagen Atomics sells four product lines: pumped molten salt test loops (Version 5.6, up to 600 deg C and 300 l/min), highly purified fluoride and chloride salts (FLiNaK, FLiBe, chloride, purified to below 20 ppm oxides), nuclear-grade enriched lithium (Li-6 and Li-7 as LiF), and professional molten salt testing services at its Copenhagen facility.”
“Copenhagen Atomics ships test loops and salt products worldwide. Loops come with CE marking for Europe and can be fitted with UL-approved components for North America. Salts ship in vacuum-sealed containers to limit moisture uptake during transit. Contact the sales team for lead times and shipping costs to your region.”
“Yes. Copenhagen Atomics specialists provide hands-on installation support at the customer site. The loop’s WebUI and cloud data platform provide remote access to real-time test data from any browser. Software and firmware updates are delivered through the WebUI. Ongoing support is available through the customer-specific login system.”
“Version 5.6 is 120x80x215 cm (47x31x85 inches), it cannot stand up against a wall or other equipment when it is operating. You need a minimum 20 cm space around the loop in order for the heat to dissipate.”
“By default the loop uses a 32 Amp, 350 – 420 Volt, 3 phase European CEE connector. It can run on 45 – 65 Hz. American customers typically buy a transformer, which is readily available to step down American 480 Volt industrial supply.”
“The loops we sell in Europe come with CE marking. You can ask for our certification of conformity. For the US market, these are optionally fitted with UL approved cabling and electronics.”
“Several of our customers use the loops as pumping stations, where they pump salt through some external equipment. Because molten salt compatible pumps are not readily available many of our customers simply use our loops as a pumping station.”
“It will soon be possible to run tests with natural uranium and natural thorium bearing salts in test tubes (static tests) or test loops (high flow rate tests).”
“At an additional cost it is possible for CA to install your equipment inside a private room. However a short list of named CA personnel must have access to the room as well as firefighters in case of fire. We can set up access logs and remote accessible video surveillance in the room if you want.”
“Yes we can agree on procedures where the customer (you) are invited to participate every time the test loop (or test tube) is opened and inspected or changed. This will give you a lot of knowledge about how to operate molten salt loops and how to avoid corrosion, pump failure, etc.”
“There are two routes. Professional investors with EUR 100,000 or more can participate directly in new share issuances (capital increases).”
“No. Copenhagen Atomics is a private limited company.”
“There is no fixed minimum for secondary share purchases. For direct participation in a capital increase, the practical starting point is EUR 100,000. The majority of direct investors are high net worth individuals (HNWIs) and family offices. Please use the form to inform us of your desired investment amount. For freely transferable B-shares there is no minimum amount.”
“Copenhagen Atomics targets a 10x to 100x return within 10 years, depending on how long the investor holds shares and the timing of a public listing. These are forward-looking estimates and not a guarantee. As with any pre-commercial technology company, investment carries a risk of partial or total loss.”
