The initial costs of nuclear energy are nothing more than the reactor itself, there is safety, insurance, etc., but Nuclear Engineering International estimates that, given lower fuel costs, a given ship could break even within 10 to 20 years. Norwegian shipbuilding company Ulstein has developed a design concept for a cruise ship powered by a molten salt nuclear reactor. In the company's concept, the 500-foot-long, 60-passenger ship, named Thor in reference to the Norse god, as well as the thorium used in the reactor core, would generate its electricity with the reactor on board. The ship would also serve as a charging station for a fully electric company ship called Sif, named after the goddess who was Thor's wife.
BERLIN Forget about short trips to space. A flying nuclear-powered hotel promises to keep its head permanently in the clouds. The Sky Cruise high-flying concept shows a gigantic airplane look to a cruise ship that can be constantly in the air. Developers imagine 5,000 guests will arrive on passenger planes that dock with it.
Savannah looked like a normal cruise ship. With a swimming pool for taking a dip, a dining room and a living room that doubles as a cinema room. But there is one thing that differentiates this ship from any other. Within this unmarked space, a few meters from the passenger cabins, there was a nuclear reactor.
Something unheard of on a passenger ship sooner or later. How to go around the earth for years without ever stopping. In the 1960s, nuclear energy was considered a revolutionary, almost unlimited source of energy. But what was less certain was whether putting a nuclear reactor on board a civilian ship was really a good idea.
As one of the first ships powered by a nuclear reactor, N, S, Savannah was to prove that nuclear power was a safe, clean and almost unlimited source of energy that could revolutionize ships. Because to make a trip around the land, a typical ship will burn more than twenty thousand barrels of bunker oil. All the time, emitting toxic smoke into the atmosphere. Savannah was designed to make that same trip without burning anything at all.
Because it could go around the Earth using just a few pounds of a new type of fuel called uranium. Replacing an oil-burning engine with a small nuclear reactor promised to make the ships of the future more economical, faster and more reliable. It would also eliminate the need for large fuel tanks, freeing up more space for cargo and passengers. Nuclear-powered ships could also travel for years without refueling, and travel at much higher speeds.
Open new trade routes that could reshape maritime trade. But despite all the promises of nuclear energy, the world has good reason to be skeptical. In the 1950s, nuclear energy meant only one thing. Its enormous destructive potential and the hidden dangers of radiation were widely feared.
Nuclear weapons have existed for almost a decade, but the peaceful use of nuclear energy remains a new concept. President Eisenhower Launches Atoms for Peace Program. In an effort to win hearts and minds, research, funding and equipment would be sent around the world to promote the peaceful use of nuclear energy. Savannah would be built as a floating example of what a future driven by atomic energy could offer.
As the first of its kind, the ship would carry passengers and cargo at the same time. Savannah was designed to look like the ship of the future. From the teardrop-shaped superstructure to the aerodynamic loading cranes, everything on this boat was designed to stand out. But what really differentiated it was the power plant.
Savannah's 74-milliwatt cylindrical reactor was designed with overhead access for refueling. Along with the pressurized water reactor, primary coolant circuit and steam generator, it is housed in a 50-foot containment vessel covered with lead, concrete and polyethylene. To keep passengers and crew safe, a few meters from the reactor, engineers incorporated layers of protection. The reactor was surrounded by a primary radiation shield, a thick steel containment vessel and a 500 ton biological shield.
To counter inclement weather, Savannah introduced one of the first ship stabilization systems, which used hydraulically actuated fins to counteract roll movements. The ship also had a reinforced hull and energy absorbing structures to protect against a collision with another ship. And in the unlikely event that Savannah sank, the reactor was designed to shut down automatically and one-way valves would flood the containment vessel with seawater, preventing radioactive material from escaping. Engineers had thought of every possible disaster scenario and Savannah builders boldly claimed that they were glowing with the safest ever built.
In May 1964, Savannah embarked on an ambitious world tour to demonstrate the merits of nuclear energy. Over the course of a year, he made visits to the U.S. UU. Cities along the East Coast and more than a dozen European ports, crossing the Atlantic several times in the process.
The ship traveled almost 150,000 kilometers, using only 35 pounds of uranium. Every time Savannah arrived at a new port, huge crowds would form to greet him. In the first year alone, 1.4 million people lined up to tour the ship. Savannah's world tour had gone fantastically well, generating enormous public interest and a lot of positive press.
Savannah's commercial operator was so happy with the ship's performance, they urged Congress to fund another four nuclear ships based on the Savannah design. And back in the United States, additional crews were being trained in anticipation of serving aboard future nuclear ships. If nuclear propulsion was really the future, it seemed that momentum was building up. Savannah had made nuclear propulsion seem easy, as the ship sailed effortlessly from port to port.
But hidden behind the sleek lines and glistening white paint, there was a harsh reality. There was nothing easy about operating a nuclear ship. Before Savannah could reach a port, she needed a special permit. And the request had to be made months in advance.
And Ports often refused for reasons of. Therefore, behind the scenes, Savannah representatives would have to fly well in advance to start negotiating deals. Covering everything from how to respond if the ship caused a nuclear accident to who would be responsible. Gut skepticism about floating nuclear reactors wasn't going to go away overnight.
And to make matters worse, Savannah's design wasn't very practical. The unusual half-passenger, half-load configuration meant the boat wasn't good for hauling either. Passenger accommodations took up a lot of space, while cargo holds were too small. And with so much emphasis on striking design, the ship's sleek lines made it difficult to handle the cargo.
Savannah also needed a highly trained crew, about a third larger than on a conventional ship. For a ship built to demonstrate that nuclear power could be commercially viable, Savannah seemed to do the opposite. Despite the ship's operator publicly bragging about Savannah's performance, its operating costs were heavily subsidized, consuming millions each year in taxpayer money. But, in a very important way, the Savannah could still be considered a success.
Because it helped inspire other countries to build their own nuclear-powered ships. In 1964, West Germany launched the NS Otto Hahn. In 1976, the Japanese launched the NS Mutsu nuclear ship. And, a fourth, the Soviet Union's nuclear cargo ship was built in the 1980s.
However, public protests led to ships being banned from entering major ports, and port workers, fearing radiation exposure, refused to unload cargo from the ship. Otto Hahn carried cargo for 9 years, but his reactor was eventually removed and replaced by a conventional diesel engine. Mutsu never carried cargo, and after having traveled only 82 thousand kilometers, its reactor was also replaced by a Diesel engine. Along with a handful of nuclear icebreakers, Russia still occasionally operates the only remaining nuclear cargo ship, mostly carrying military cargo in the far north of the country.

The company is now exploring MSR technology because it operates at a much lower pressure than other nuclear reactors and cannot undergo a fusion.
The power generation service vessel would also be built as a rescue ship that could help ships in distress in remote areas such as Antarctica, the company said. Ammonia is a carbon-free energy carrier that could be produced using the thermal energy of nuclear power plants. SNC-Lavalin and Moltex Energy Partner to Advance Development and Deployment of Small Modular Reactor Technology in Canada, Companies Announced Last Week at Canadian Nuclear. The Savannah nuclear power plant, a pressurized water reactor that created steam to power engines, was retired decades ago, but residual radioactivity remains in pipelines and other equipment within the reactor containment area.
Muren said Ulstein's idea is that a service vessel with a small nuclear reactor can serve as a floating power plant for up to four small, fully electric expedition ships sailing in a region such as Antarctica. With a small nuclear reaction that powered the engines, the Sky Cruise could remain in flight for several years in a row. And while the public remains focused on the potential dangers of nuclear energy, emissions related to shipping have resulted in four hundred thousand premature deaths each year from lung cancer and cardiovascular disease. It's a cruise ship, a nuclear cruiser, said James “Jay Tarzia, co-owner of Radiation Safety and Control Services of Seabrook.
The biggest attraction of nuclear energy is probably that you can go a long time without having to refuel. Lubiatowo-Kopalino, a location in northern Poland near the Baltic coast, has been selected as the preferred site for the country's first nuclear power plant, and won over the nearby. A joint venture called Nuclear Ship Support Services, which consists of Radiation Safety and Control Services together with Energy Solutions of Charlotte, N. .
