nuclear powered vessels

I have a question although not dealing with warships. End 1950s-1960s the Warnow Werft, Rostock, East Germany intended to built a nucelar-propelled cargoship/freighter to be completed by 1965; the decision for the project dat from 19 November 1957. In 2023 professor-ing. Franz Spychala held in...

Single steam loop? Go F yourself, Mister DeGaulle! There's a reason everyone else keeps the primary loop inside the reactor compartment and lets it boil water in the secondary loop to spin the turbines.

Hi! ALL HANDS MAGAZINE SEPTEMBER 1961 PAGE: 39 "OPERATION CRYSTAL BALL" In 1961 RADM Roy S. Benson asked everyone in the sub force to submit ideas for "future" submarine weapons etc. Some ideas - "depth charging" surface craft - underwater submarine tender - sailless submarines - addition of...

I came across this project in a 1968 United States Atomic Energy Commission booklet, The ATOM and the OCEAN, by E. W. Seabrook Hull (can be found on Project Gutenberg here). The National Science Foundation had proposed an Arctic Drift Barge for Arctic research, which would have a nuclear plant...

Does anyone have any information on the French design at least? The program was a precursor to the equally ill-fated (non-nuclear) Polar 8 icebreaker program of the 1980s. The only hard info I have on the French proposal at the moment is that the reactor was a CAS (Advanced Series Boiler)...

Navy's Next Attack Submarine Will Be Wider And Based On The New Columbia Class Missile Boats The SSN(X) design will be wider than the present Virginia class, offering improved capabilities and increased stealthiness underwater. Does anyone have any thoughts on displacement, size and weapon...

Surprised that this wasn't being discussed or have its own thread but it regards militarization, icebreaker projects, living in cold conditions, transporting fuel, possibly another area of conflict later. Examples of starting off thread to get the general idea...

Also somewhat confusingly referred to as the Leader-class, not to be confused with what is now the Project 23560E Shkval-class light cruiser. https://www.navalnews.com/naval-news/2020/07/russian-shipyard-begins-construction-of-leader-nuclear-powered-icebreaker/ ORIGINAL CAPTION: The Leader...

As I hate cluttering up the NIGS thread with speculative what-ifs I have finished my tinkering with Hampshire rebuilt with the NIGS as depicted by portions of the NIGS plans. The only non-NIGS radars are for 978 for surface-search and a Mk 10 IFF antenna and the ESM systems. I kept both 'Cooky'...

This was a project intended to provide three (correction, four) atomic powered high speed container ships for use on Essential Foreign Trade Route No. 12, between the U.S. Atlantic Coast and the Far East. The ships would have used the AEC Maritime Reactor, a clean sheet gas-cooled reactor design...

While virtually all maritime nuclear reactors (save the Soviet Alfas and Papas, which ran on lead-cooled fast reactors with a steam secondary circuit) were light water PWRs, other reactor designs have been prototyped which may be of use for maritime nuclear propulsion. Concepts include direct...

"Will China's Next-Generation Supply Ship be Nuclear-Powered?" "On September 6, 2018, China’s comprehensive supply ship Hongzehu (Hull 881) was honorably retired, marking that the Chinese Navy has entered a new era of modernization. With its retirement, perhaps the country’s next-generation...

"China has opened the bid to construct its first nuclear-powered icebreaker support ship, a move to prepare for the construction of a nuclear-powered aircraft carrier, military observers said. China National Nuclear Corporation on Thursday opened public bidding for the nuclear-powered...

Sorry if this has been flagged previously, I have tried searching, but so far, to no avail. I am (still) reading Hennessy and Jinks' 'The Silent Deep', and have to say it is a very informative tome. There is reference made to discussions held during the period when Dennis Healy was Defence...

The first commercial nuclear reactor in the United States, Shippingport, was derived from a reactor originally designed for a cancelled nuclear powered aircraft carrier. I haven't been able to find any information on this aircraft carrier, and I don't think the Shippingport reactor is related to...
