Nuclear energy for maritime shipping and coastal applications
The Boston-based Deon Policy Institute has published a white paper that examines the applications of nuclear energy in the maritime sector—specifically, floating nuclear power plants and nuclear propulsion for commercial vessels. Topics covered include available technologies, preliminary cost estimates, and a status update on the regulatory framework.
Unique opportunity: The paper points out that nuclear energy has the potential to benefit the shipping industry with high energy efficiency, lower operating costs, and zero carbon emissions. The report has a special focus on Greece, a nation that controls about 20 percent of the global commercial fleet and thus has an opportunity to take a leading role in the transition to nuclear-powered shipping.

To improve the economic characteristics of fast reactors, researchers are developing advanced structural materials for application to reactor components. These advanced materials provide higher strength at elevated temperatures. Coupled thermal-hydraulic and structural analyses have been carried out to investigate the benefits of the advanced structural materials for a specific fast reactor design: the Advanced Burner Reactor (ABR) developed at Argonne National Laboratory. The benefits of the advanced materials, in terms of increased design margins, possible longer lifetime, thinner structures, and higher operating temperatures, were calculated for the major ABR structural components, including the reactor vessel, the core support structure, the intermediate heat exchanger, the intermediate heat transport system piping, and the steam generator. For each structure, the possible reduction in the component thickness was calculated and was converted into estimates of the commodities savings provided by the use of the advanced materials. Overall, a significant material mass saving of [approximately]40% was calculated for the considered fast reactor structures.
