Ulstein began its thorium-powered Thor concept with a question: What if we could design and build a vessel with an abundant emission-free energy source able to support other vessels with clean fuel? There are some 160 vessels worldwide with nuclear reactors, nearly all of them military ships or submarines, but will we ever see a nuclear superyacht?<a data-gid="gid://syiq/Company/4539" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Ulstein Verft AS (Company)">Ulstein</a> first unveiled its 149-metre Thor concept in 2022 together with the full-electric cruise ship concept Sif. With carbon emissions and alternative fuels in the spotlight, the disruptive project garnered considerable industry interest and last year the Norwegian group was invited to join a panel of class societies and flag states to discuss nuclear energy at the Superyacht Forum during <a data-gid="gid://syiq/Company/4374" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="METSTRADE (Company)">METSTRADE</a> in Amsterdam. <img src="https://photo-assets.superyachttimes.com/photo/345476/image/large-86e6b7f074b0d025daacd8ef278312c7.jpg" data-gid="gid://syiq/Photo/345476">“What was interesting was that each session was given 45 minutes before breaking for lunch, but ours had a record show of people and lasted one-and-a-half hours,” says Øyvind Gjerde Kamsvåg, Chief Designer at <a data-gid="gid://syiq/Company/4539" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Ulstein Verft AS (Company)">Ulstein International</a>. “Most people were sceptical about nuclear power at first, but many were converted by the end of the session.” <img src="https://photo-assets.superyachttimes.com/photo/345475/image/large-fe152c3ab648f45f95a44efcbb814fa2.jpg" data-gid="gid://syiq/Photo/345475">The clever thing about Thor from a superyacht perspective is that it is categorised as a Replenishment, Research and Rescue (3R) vessel and conceived as a floating power and charging station. Equipped with a Micro Modular Reactor (MMR) or a thorium-powered Molten Salt Reactor (MSR), it would be able to generate 20MWe of clean, safe electricity for recharging a new breed of full-electric vessels at sea, with the potential to also be plugged into the renewable energy grid.&nbsp;“Thor would be able to satisfy a variety of different needs in the market,” continues Kamsvåg. “So you can use it as a first responder, you can use it as a scientific research hub, you can use it as an energy replenishing unit. It can serve so many functions once we start to explore the nuclear energy infrastructure.” <img src="https://photo-assets.superyachttimes.com/photo/345477/image/large-0429b7fc1a60397791907c4ab4370335.jpg" data-gid="gid://syiq/Photo/345477">The alternative to a mobile charging station like Thor is installing a nuclear reactor on board the yacht itself, which comes with other potential advantages. As the fuel is contained within the reactor there are no fuel tanks, combustion air intakes or exhaust stacks that take up valuable space. Besides being emission free, nuclear reactors require no regular maintenance and provide extremely long intervals of operation before refueling. The latest reactors on submarines, for example, are designed to last the lifetime of the ship, during which time they circumnavigate the globe many times. <img src="https://photo-assets.superyachttimes.com/photo/345478/image/large-14fd245191f94bb52f00df8512f04a23.jpg" data-gid="gid://syiq/Photo/345478">“Superyacht clients like the idea of Thor because the reactor is separate from the yacht itself,” says Kamsvåg. “But we’re starting to see micro reactors and associated systems that can be scaled to fit on bigger superyachts. That is still a bit further up the road, but I think both scenarios are equally interesting.”<img src="https://photo-assets.superyachttimes.com/photo/345479/image/large-d6d867f4205068d87c224002e1e073ca.jpg" data-gid="gid://syiq/Photo/345479">Theory of relativity&nbsp;<a data-gid="gid://syiq/Company/29" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Feadship (Company)">Feadship</a> considered the question with its Relativity concept back in 2012 and concluded that “technically speaking, a nuclear fission reactor design could be made, customised to fit the available space on a yacht and dimensioned to allow for all operating conditions.” Like <a data-gid="gid://syiq/Company/4539" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Ulstein Verft AS (Company)">Ulstein</a>, thorium was envisaged as fuel in a high-temperature, low-pressure molten salt reactor. The heat output would then be converted to mechanical power using high efficiency, closed-cycle Helium gas turbines to drive the generators. But the technology was not readily available and issues associated with insurance and port controls rendered the idea compelling but ultimately impractical. More recently, a 2023 joint study between the <a data-gid="gid://syiq/Company/29" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Feadship (Company)">Feadship</a> R&amp;D department and Delft University tackled the topic again.<img src="https://photo-assets.superyachttimes.com/photo/345484/image/large-79faf9b85628a8a8924851eb64797f28.jpg" data-gid="gid://syiq/Photo/345484">The study identified that a IV generation Micro Modular Reactor using a uranium, carbon and oxygen fuel kernel might be the best fit for the load profile of a superyacht. A fraction of the size of a conventional nuclear reactor, MMRs can be factory-assembled and transported as a unit for installation. Both <a data-gid="gid://syiq/Company/29" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Feadship (Company)">Feadship</a> and <a data-gid="gid://syiq/Company/4539" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Ulstein Verft AS (Company)">Ulstein</a> have looked into the volumetric requirements of installing such reactors on board and found they would occupy less space than alternative fuel systems. However, the <a data-gid="gid://syiq/Company/29" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Feadship (Company)">Feadship</a> study underlined the massive weight implications of the lead and concrete shielding materials required. Depending on the size and power of the reactor, the whole installation could weigh over 2,300 tons, more than doubling the weight of an 80-metre yacht!<img src="https://photo-assets.superyachttimes.com/photo/345480/image/large-6708471d22a0871e0106b1de58ddd049.jpg" data-gid="gid://syiq/Photo/345480">This is just one reason why <a data-gid="gid://syiq/Company/29" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Feadship (Company)">Feadship</a> believes a more realistic role for maritime nuclear power would be to make green hydrogen or methanol either onshore, or close to shore, for use as carbon-free fuels. This view was backed up by Ronno Schouten, Design Manager at <a data-gid="gid://syiq/Company/29" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Feadship (Company)">Feadship</a>, at the Alternative Fuels conference during the 2024 Monaco Energy Boat Challenge:<img src="https://photo-assets.superyachttimes.com/photo/345483/image/large-fce43549aacd84d60dd04bab4f6b42ee.jpg" data-gid="gid://syiq/Photo/345483">“Yes, a nuclear-powered yacht will be technically feasible sometime in the future, but why integrate an MMR with an average onboard load of about 10 percent, when you can put it to better use onshore making green fuel like methanol for multiple yachts at maximum power?”<img src="https://photo-assets.superyachttimes.com/photo/345481/image/large-613ba1e28b699b2098c84884a05656cc.jpg" data-gid="gid://syiq/Photo/345481">High stakes&nbsp;Although technically possible, onboard nuclear power faces other hurdles. Public perception of the danger of radioactivity, heavily influenced by high-profile accidents like the Chernobyl and Fukushima disasters, is a major concern although sometimes overstated. The latest nuclear technology makes leakage or meltdown highly unlikely, but checks need to be put in place to prevent accidents due to grounding, impact, collision, machinery damage, fire, explosion, and other causes. Last but not least is the near total lack of maritime legislation, insurance policies and flag state rules covering nuclear reactors on yachts.“The regulatory bodies and flag states all agree that nuclear will play a role if we want to go into emission free or more sustainable shipping,” says Jose Jorge Garcia Agis, Managing Director at <a data-gid="gid://syiq/Company/4539" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Ulstein Verft AS (Company)">Ulstein International</a>. "The main challenge today is that the international regulations for nuclear-powered ships are outdated and based on old nuclear technology. This makes it very difficult to implement them on modern vessels. Ship design is heavily influenced by regulations; we work within the rules. Without clear rules, we have to define our own framework and then seek approval, rather than designing around an existing framework."<img src="https://photo-assets.superyachttimes.com/photo/345487/image/large-d4c783c0accbd70aef80541d535d2483.png" data-gid="gid://syiq/Photo/345487">The commercial shipping industry is aware of what is at stake. Last year, <a data-gid="gid://syiq/Company/295" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Fincantieri Yachts (Company)">Fincantieri</a> and <a data-gid="gid://syiq/Company/1457" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="RINA (Company)">RINA</a> signed an agreement with newcleo to carry out a feasibility study for applications in shipping for the nuclear tech company’s lead-cooled, small modular reactors. In August <a data-gid="gid://syiq/Company/1452" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lloyd's Register (Company)">Lloyd’s Register</a> announced a project together with Core Power – a leading developer of floating nuclear technology solutions – and A.P. Mølle - Maersk &nbsp;to assess the viability of a nuclear-powered container ship that could be deployed in European waters. <a data-gid="gid://syiq/Company/1452" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lloyd's Register (Company)">Lloyd’s Register</a> further launched a new report at the <a data-gid="gid://syiq/Event/224" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Monaco Yacht Show - 2024">Monaco Yacht Show</a> in September entitled Fuel for Thought: Nuclear for Yachts that highlights its potential as a clean, powerful and long-lasting energy source.&nbsp;“Nuclear energy offers the potential to be as transformational to shipping as the shift from wood to iron or from sail to steam,” says Engel-Jan de Boer, Global Yacht Segment Director for <a data-gid="gid://syiq/Company/1452" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lloyd's Register (Company)">Lloyd’s Register</a>. “Unlike alternative fuels that might serve as direct replacements for traditional oil-fired systems, nuclear power represents a fundamental shift that could redefine luxury yachting”. &nbsp;<img src="https://photo-assets.superyachttimes.com/photo/345486/image/large-1c295dae166e1f997955f4ab6a7705bb.png" data-gid="gid://syiq/Photo/345486">Do we have a choice?The first nuclear-powered merchant ship, NS Savannah, was launched way back in 1959 by the New York Shipbuilding Corporation in New Jersey, USA, as one of only four nuclear cargo ships ever built. A demonstration vessel designed to serve also as a passenger ship, she was appointed with 30 air-conditioned ensuite staterooms, dining facilities for 100 passengers, a lounge that could be converted into a movie theatre, a swimming pool, veranda and library. However, high operating costs, low commercial value, limited port access and public concerns about safety led to her being taken out of service in 1971.<img src="https://photo-assets.superyachttimes.com/photo/345485/image/large-2718607a22e7678dd1cb76030ebc511a.png" data-gid="gid://syiq/Photo/345485">Sixty-five years after the launch of NS Savannah, the situation is very different. Nuclear technology is far more advanced, the reactors are much smaller and safer, and the <a data-gid="gid://syiq/Company/4531" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="International Maritime Organization (Company)">IMO</a> has doubled down on carbon-reduction ambitions by setting a net-zero emissions goal by 2050. Moreover, geopolitical tensions around the world are making the energy independence offered by the nuclear option an increasingly attractive proposition. In this scenario, another Norwegian research project, NuProShip (Nuclear Propulsion of Merchant Ships), is aiming to develop a commercially viable nuclear technology for ships that satisfies all stakeholders and requires no subsidies after the initial development process.&nbsp;Heading up the NuProShip project is Jan Emblemsvåg, professor of ocean operations and civil engineering at the Norwegian University of Science and Technology (NTNU). He believes that given the poor energy density of other low- and zero-carbon fuels we might not have much choice but to embrace nuclear power for ocean-going vessels, and draws on a very graphic example to make his point: if hydrogen’s energy density was one metre long, uranium would be 32 kilometres long and thorium would be 38 kilometres long.“This is what the green transition must be about,” he says. “We need to learn how to deal with these two atoms and then we should be just fine.”This article was featured in&nbsp;<a href="https://www.superyachttimes.com/magazine/how-to-build-it-issue-6" target="_blank">Issue 6 of How To Build It.</a>&nbsp;You can read all the articles from this edition&nbsp;<a href="https://www.superyachttimes.com/magazine/how-to-build-it-issue-6" target="_blank">here</a>, and stay up-to-date with all previous editions&nbsp;<a href="https://www.superyachttimes.com/magazine" target="_blank">here</a>.

Ulstein’s X-Bow explorer yacht Olivia O in Malta

The 89m explorer yacht Olivia O, built by Ulstein in 2020, is seen here anchored in Malta.

Strong headway has been made with the construction of the 34.9-metre explorer yacht Project Fox at <a data-gid="gid://syiq/Company/209" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Pendennis Shipyard Ltd (Company)">Pendennis</a> and she’s on course to meet her delivery date of 2023.<img src="https://photo-assets.superyachttimes.com/photo/220718/image/large-158509db47bdb762e5a7a4bc4aff6355.jpg" data-gid="gid://syiq/Photo/220718"> Project Fox seeks to be a trailblazer in the explorer yacht segment. She offers an interior and exterior design by <a data-gid="gid://syiq/Company/6663" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Q London (Company)">Q London</a> laid onto a hull by <a data-gid="gid://syiq/Company/7" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Diana Yacht Design B.V. (Company)">Diana Yacht Design</a>, a 3,600 nautical mile range, 295 GT of interior volume and accommodation for up to eight guests. James Ratcliffe, Managing Partner of <a data-gid="gid://syiq/Company/6663" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Q London (Company)">Q London</a>, explained that he stuck to a clean, minimalist interior design that’s flexible and easy to customise, to keep her appeal high for a wide range of potential clients. In lieu of traditional teak, <a data-gid="gid://syiq/Company/6663" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Q London (Company)">Q London</a> opted for the more sustainable substitute, designed by Tesumo.<img src="https://photo-assets.superyachttimes.com/photo/220717/image/large-f799c97d07d211a4a2b0ff37a67c1f26.jpg" data-gid="gid://syiq/Photo/220717"><img src="https://photo-assets.superyachttimes.com/photo/220715/image/large-6b30f54aa3d456d4505380ee7e090ed1.jpg" data-gid="gid://syiq/Photo/220715">But what makes Project Fox truly unique is that her design pivots on her 103.5 square-metre main deck aft, which boasts heaps of space for tenders, toys and all the paraphernalia necessary for adventure. When deployed, the spacious main deck is versatile and can cater to an all manner of needs. Even at just 34.9-metres, Project Fox&nbsp;is self-sufficient, meaning an owner won’t need a trailing shadow or support vessel for their excursions. &nbsp;<img src="https://photo-assets.superyachttimes.com/photo/220710/image/large-cc89bd7e28b1d194d05fbefa6ae9c00e.jpg" data-gid="gid://syiq/Photo/220710"><img src="https://photo-assets.superyachttimes.com/photo/220713/image/large-54153d4e5d1e3d1d3eb0b81b8abc34ce.jpg" data-gid="gid://syiq/Photo/220713">“Experience is the new currency. So a yacht that can deliver an experience that others can’t is becoming an increasingly relevant topic,” Sherwood added. “Project Fox proves that you don’t have to spend an 80-metre budget to have a yacht that will take you to interesting places anymore.” Even at 34.9-metres then, Project Fox is expected to rival the likes of the 76.9-metre motor yacht <a data-gid="gid://syiq/Yacht/6668" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="La Datcha76.9m (252'4&quot;)Damen Yachting2020">La Datcha</a> by <a data-gid="gid://syiq/Company/1821" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Damen Yachting (Company)">Damen Yachtin</a>g and <a data-gid="gid://syiq/Company/4539" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Ulstein Verft AS (Company)">Ulstein Verft AS</a>’ 88.51-metre <a data-gid="gid://syiq/Yacht/6031" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Olivia O88.51m (290'5&quot;)Ulstein Verft AS2020">Olivia O</a>.Read:&nbsp;<a data-gid="gid://syiq/Article/53850" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="In-build 35m Pendennis superyacht Project Fox offered for sale (2021-10-07 13:15:00 +0200)">In-build 35m Pendennis superyacht Project Fox offered for sale<img src="https://photo-assets.superyachttimes.com/photo/220696/image/large-ea50e65d80c851c51891d57cd60f2afd.jpg" data-gid="gid://syiq/Photo/220696"></a>For the team at <a data-gid="gid://syiq/Company/159" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Burgess (Company)">Burgess</a> and <a data-gid="gid://syiq/Company/209" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Pendennis Shipyard Ltd (Company)">Pendennis</a>, the understanding that the ability to go anywhere takes a top priority for owners today.
