The US Navy currently has the largest fleet of nuclear-powered aircraft carriers[4] and nuclear-powered submarines. Besides its low-maintenance advantage, the entire unit can be seamlessly replaced once its lifespan concludes. Nuclear power has already been used on ships such as ice breakers that operate in polar regions. Crews continue work on the deck of the Savannah as decommissioning continues.The ultimate fate of the ship is uncertain. Erhard Koehler, Senior Technical Advisor for the ship, climbs the passenger staircase from the lobby to the lounge area.

And decommissioning the ship has taken decades and cost far more than it could have ever made moving cargo or people. It controlled a pressurized water reactor that used low-enriched uranium to produce heat. That heat was turned into steam that could run the ship's turbines, spinning the propeller and also producing electricity. The Savannah could cruise at 20 knots, which is similar to the speed of most cruise ships today. Talking to the magazine Maritime Executive in 2015, one industry consultant said, “When you ask educated, professional groups whether they believe we should become more reliant on nuclear power, percent are positive. The shift towards nuclear propulsion in the cruise industry raises several questions—notably, the safety of atomic power on ships.

Consequently, ship manufacturers are assessing their options for zero-emission fuels, and nuclear power is one of them. The interior of the Savannah remains a time capsule of the mid-century era in which it operated. The main lobby of the cruise ship welcomed paying passengers from 1962 to 1965. Muren said Ulstein's idea is that one service vessel with a small nuclear reactor could serve as a floating power station for up to four small, all-electric expedition ships sailing in a region such as Antarctica. The company unveiled an outline of its concept for both an all-electric cruise vessel and the nuclear power-generating service vessel that would keep the all-electric cruise vessel charged. It also showed off artist's renderings of what the two vessels would look like.

Norway-based Ulstein is calling its concept for the service ship Ulstein Thor — a nod to the thorium fuel that will be used in the vessel's electricity-producing reactor that also evokes the power of the Norse god of the same name. Get ready to set sail aboard Norwegian Star and discover the southernmost edge of the South Pole, Antarctica. Embark on an expedition cruise and witness breathtaking icebergs and penguins by the beach from the top deck, all as you take in once-in-a-lifetime moments. Don't miss cruising Antarctica and experiencing some of the most exhilarating destinations in the world.
Reactor
It represents the volume of uranium fuel needed to let the Savannah travel 454,000 nautical miles– enough to circumnavigate the world well over a dozen times. Traveling the same distance with conventional fuel would have required approximately 28 million gallons of it. However, using nuclear power for cruise ships will be something that the public will need to consider and understand. The transition involves technological advancements and needs to address safety concerns, environmental implications, and societal acceptance. Submarines, aircraft carriers, and icebreakers have safely relied on nuclear power for years. Modern reactor designs, especially those like the LFRs, are equipped with built-in safety features that further enhance this security.

Refurbished as part of the Norwegian Edge program in 2018, Norwegian Star shines with upgrades. The extensive enhancements include upgrades to staterooms, public spaces, restaurants, bars and lounges. Start the day at Mandara Spa, where you can revive, refresh and recharge.
Situated off the coast of Antarctica, Elephant Island is named after the elephant seals that populate it and due to the island being shaped like an elephant head. Rugged mountains, glistening sheets of ice and unique wildlife add to the mystique of this remote destination. Despite its seemingly unforgiving, yet hauntingly beautiful landscape, legions of tuxedoed-looking penguins waddle across the rocky terrain while giant elephant seals lounge on its shores. Deception Island is a mountainous, horseshoe-shaped destination located off the coast of Antarctica in the South Shetland Islands.

That small amount of uranium can power the ship for decades before it’s spent, freeing up space on the ship that would normally be used to carry conventional fuel. A wooden block in the main lobby illustrates the amount of uranium fuel needed to sail around the world more than a dozen times. The bridge would send orders to the reactor control room, which could change the power output of the nuclear core as needed. The power-generating service ship would also be built as a rescue ship that could aid vessels in distress in remote areas such as Antarctica, the company said.
Ike was also keen to prove the myriad ways nuclear could benefit everyday Americans. Thus one stateside AFP project was the NS Savannah, a civilian nuclear ship launched in 1959 as a harbinger of America’s rosy atomic future. The operators could also command an emergency shut-down, or scram, of the reactor core. Scrams were rare aboard the Savannah, but one did take place in 1964, when the ship passed through a hurricane.
Cruise ships have traditionally been powered with bunker oil, also known as heavy fuel oil, or another grade of oil called marine gasoil. Additionally, some ships in recent years have been designed to run on Liquefied Natural Gas, which is touted as a cleaner fuel than traditional marine-grade oils. That incredible power - that is why I am so obsessed with all things nuclear - well, partially, because I'm also obsessed with what this ship says about us. We turn a magic equation into a powerful bomb, build enough of them to destroy the world. And at the same time, we're like, hey; why don't we try doing something fun like build a cruise ship, see how far it can go? While the Savannah's nuclear reactor was revolutionary, the rest of the ship was actually unremarkable for the time it was built.
"A very small amount of thorium can power a ship for 25 years," Muren said. Muren told TPG the concept could become a reality within 10 years if the industry and politicians signed on to the idea. Muren spoke one-on-one with TPG moments after Ulstein revealed the concept at the company's booth at Seatrade Cruise Global, which is taking place this week at the Miami Beach Convention Center. The Nuclear Ship Savannah offers a snapshot of a nuclear future that never quite came to pass.
Enjoy delicious dining, from Irish pub classics at O'Sheehan's to classic hibachi at Teppanyaki. In the Port of Baltimore, a ship is docked that hasn't transported passengers for more than 50 years. And although it stopped only after a few years, largely due to a lack of money, it was successful in part. Public awareness campaigns, transparent discussions about safety protocols, and environmental impact assessments will ensure that those who love to cruise are informed, confident, and supportive of such a significant shift. The cornerstone of this venture is Newcleo’s groundbreaking LFR (Lead-cooled Fast Reactor).
These 14-day itineraries cruise from Iceland to Greenland and back from September into early October. As the majority of the voyage takes place above the Arctic Circle, the odds of seeing the northern lights are high, especially as solar activity tends to peak around the autumnal and vernal equinoxes in September and March, respectively. And if they don't show, well, you still get to explore Iceland's Westfjords and Greenland's eastern shores — and that's a worthwhile journey in itself. However, cruise ships rarely use all engines simultaneously, making one reactor sufficient for a medium to large cruise ship. Newcleo unveiled a new partnership with shipbuilder Fincantieri and RINA, a classification society. Though the fuel tech may seem somewhat far-fetched, it shouldn’t be discounted just yet, according to several industry leaders who spoke during a panel discussion at the Seatrade Cruise Global conference in Miami earlier this month.
In November of last year, its reactor was removed and taken to Utah for disposal. Koehler says full decommissioning of the ship's nuclear components will take another two years or so. At that point the Maritime Administration can dispose of the Savannah, Koehler says, but he hopes it will be protected. Government had built the Savannah as part of a program known as "Atoms for Peace," which sought to demonstrate the good that nuclear energy could do. Savannah's origin story began in the darkest days of the Cold War.
