smokeybandit Posted August 9, 2023 Report Share Posted August 9, 2023 Nuclear obviously powers many war ships with great success. Though I'd still wonder how some people would think about sailing on a cruise ship powered the same way. https://www.cruisehive.com/ship-builder-explores-nuclear-power-for-cruise-ships/108313 ChessE4 and teddy 1 1 Quote Link to comment Share on other sites More sharing options...

Cakemeister Posted August 9, 2023 Report Share Posted August 9, 2023 (edited) The gas tank on an Oasis-class ship is about 5000 cubic meters. An Olympic-size swimming pool is about 2500 cubic meters. If the reactor takes up about the same space as the engines would, this might open up some possibilities for more bars and restaurants. Hooray! The LNG tanks on Icon weigh 300 tons each and are 90 feet long. Just think of what you could do with the extra space! Icon of the Seas Construction Update: LNG Fuel Tank Installation | Royal Caribbean Press Center The problem I see is the difference in lifespan between the reactor and the rest of the ship. The USS Nimitz is fifty years old. Plus: Edited August 9, 2023 by Cakemeister added info about the LNG tanks.

BB1 Posted August 9, 2023 Report Share Posted August 9, 2023 It seems to me that the logistics would dictate fissionable material being used all over. Sounds like a possibly bad idea unless you believe none of it would get in the hands of terrorists. That could be overly and dangerously optimistic.

JasonOasis Posted August 9, 2023 Report Share Posted August 9, 2023 According to the article in addition to exploring nuclear power they are also looking at hydrogen power fuel cells as well. I think it will be interesting to watch and see where this goes and actually comes out of all this. Right now the industry is moving towards LNG and shore power while in port which seem more like a short term solution to cutting emissions but what comes after LNG? I'm guessing we may have a clearer picture by mid to late 20230s. I have no issues cruising on a nuclear power ship, according to the article a small nuclear reactor would have an output of 30MW compared to typical engines today where 4 engines combined have an output of just 10MW. The technology is being used today on other types of vessels but one thing not discusses is how would they dispose of the reactor once the ship reaches the end of it life.

rjweber3 Posted August 9, 2023 Report Share Posted August 9, 2023 32 minutes ago, JasonOasis said: they are also looking at hydrogen power fuel cells as well. I wonder where the H2 comes from. I would guess from electrolysis of H2O. That is a pretty energy intensive process. So, what is the savings in total CO2 production unless using nuclear power to make the electricity for the electrolysis plant? 4ensic 1 Quote Link to comment Share on other sites More sharing options...
ChessE4 Posted August 9, 2023 Report Share Posted August 9, 2023 Not sure about how nuclear-powered cruise ships would be regulated, e.g., inspected and certified. Not sure cruise lines want to go there -- bad enough to keep up with health issues, CDC, and so forth. But some day it could come to pass...

JohnK6404 Posted August 9, 2023 Report Share Posted August 9, 2023 ... plus I would assume there would have to be some significantly heightened level of security with nuclear material onboard...

JimnKathy Posted August 9, 2023 Report Share Posted August 9, 2023 Several nuclear scientist folks I've followed for years all state that the type of uranium used in modern reactors isn't the fissionable material needed to make weapons...the terrorist angle doesn't seem to be an issue. teddy, Neesa, CruiseGus and 7 others 10 Quote Link to comment Share on other sites More sharing options...
twangster Posted August 9, 2023 Report Share Posted August 9, 2023 I'm open to it but I can see the same groups that protest and picket cruise ports now licking their chops to protest nuclear cruise ships coming into port.

twangster Posted August 10, 2023 Report Share Posted August 10, 2023 Thinking about this, wanna bet CA would still require the ship plug into shore power so they could sell less clean CA grid power to the ship?

Fox Forlenza Posted August 11, 2023 Report Share Posted August 11, 2023 I think it would be a brilliant idea. Nuclear power has changed drastically over the decades and is safe, efficient, and creates incredibly little waste. Definitely the way we should be looking towards on land as well.

Nathan adams Posted August 12, 2023 Report Share Posted August 12, 2023 The fuel is not available. Still have the problem of disposing of spent fuel. Many countries will not allow you to port. Why aren't shipping companies using it as a very cost effective means? I don't think it's going to happen. Quote Link to comment Share on other sites More sharing options...

Happy Cruisers Posted August 14, 2023 Report Share Posted August 14, 2023 I asked on a behind the scenes tour on Allure years ago why there haven't been nuclear powered cruise ships when the (first) world's militaries have been using nuclear power for maritime operations for years, and the engineer or whoever we were speaking to looked at my like I had just asked him to drink molten copper through a curly straw. I was taken aback by his unprofessional reaction as I didn't then and don't now consider it to be that crazy of a question. One possible issue I see is that it could become yet another reason to deny cruise ship's access to key ports. If the folks in, say, Bar Harbor, for example among other places, didn't like the idea of a big diesel ship emitting large amounts of particulates and passengers into their area, I can't imagine they'd be comforted by the news that there's now a nuclear reactor involved, too. (and I'm not suggesting that Mainers are or aren't fans of nuclear energy - just using the recent political issues with cruise ship calls there as an example). Copy and paste Norway, Canada, Alaska, etc. One would think that some of the environmental-types might be enthusiastic about nuclear ships in those areas given their beliefs around climate change, but nuclear energy has had a PR problem that goes back more than a few years, unfortunately. Net-net, I'm more comfortable with a nuclear reactor on my ship than I am riding around on top of a big LNG tank - by a country mile. All of this is riskier than good ole sludgy bunker fuel ever was, but that's none of my business. Thumper44 and rjweber3 1 1 Quote Link to comment Share on other sites More sharing options...
