Nuclear Merchant Ships?

Nuclear Merchant Ships?
Easy to dismiss but it could potentially happen. Open for thoughtful consideration and discussion.

The head of Chinese shipping giant Cosco has suggested that container ships should be powered by nuclear reactors in order to reduce greenhouse gas emissions from shipping, said to account for 4% of the global total. Shipping companies have gradually been introducing 'super slow steaming', a measure designed to cut fuel consumption and substantially reduce emissions by running engines at very low speed. However, Wei Jiafu, Cosco's president and CEO, speaking at the Senior Maritime Forum of the China International Maritime Exhibition (Marintec China) in Shanghai, said that introducing nuclear-powered ships could be an even cleaner solution. He said, "As they are already onboard submarines, why not cargo ships?" He said that Cosco is in talks with China's nuclear authority to develop nuclear powered freight vessels.

Besides safety issues (specialized crew, accidents, piracy, etc) and politcal ramifications, would Cosco purchase ships/plants from U.S. shipyards?

Jose Femenia, past chair of the engineering department at Kings Point, is the expert on this.

Jose says it is important not to use Navy cost or engineering analysis because of regulatory differences - better to use land-based small reactor models for initial engineering and business evaluation.

Recent SNAME paper on nuclear commercial vessels for Arctic Routes is a must read.

The Savannah is in need of rescue if someone wants to save the first commercail nuclear vessel!!

Pro: Zero atmospheric emissions (neither pollutants nor CO2) for properly running reactor; high power not a problem; minimal fuel costs
Con: Crew training and associated costs;
High construction costs because of exotic materials and high tech controls, structural and radiation containment vessel, etc;
Regulatory problems in some countries or ports;
Perceived (and real) risks of radiation contamination in the event of stranding, collisions, or sinking (compares with oil spill risk? Worse or better?)
Refuelling a shipyard operation that would require some weeks/months to accomplish;
Scrapping at end of service life (regulatory & environmental problems, disposal of nuclear waste).

I think nuclear power for commercial ships, while it has potential, also has a high hill to climb before it can even achieve acceptance (practicality). Whether it can ever achieve economic competitiveness is another question. The physics of ship propulsion/performance requires, for the speeds used today in most trades, such tiny powers compared to ship displacement that a technology that becomes more efficient at higher powers simply makes no sense. This is why diesel replaced steam. Unless there is some trade where 40-knot speeds would allow much higher freight rates, I don't see a niche for nuclear power until the economics changes radically.

All the reasons stated by Steve Toby show why ice class vessels are being looked at first. They use the power otherwise required to go 40 knots to 10. It changes the economics. I am not convinced myself, but I am open to it. The cost of getting the fuel to the Artic factors in to the fuel cost also.

Lloyds Register is also looking into the feasibility of nukes. I also agree with the distinguished Jose Femenia in his comment regarding use of Navy models in planning for commercial nukes. A stumbling block in any commercial venture here in the US is the Navy mentality of the few remaining yards here wherein "money is no object". There has been some work into a conceptual design for a nuke container vessel in the US headed up by some of the former Savannah folks.
