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.

A direct-electrical-heating apparatus was utilized to perform fundamental experiments on short, unirradiated, unclad UO2 pellet stacks to investigate the effect of varying the energy-deposition rate and energy level on the mechanical response of the fuel to transient heating. Results show that as the rate of energy input to the UO2 pellet stacks increases, (a) the energy failure threshold decreases and (b) the areal melt fraction at failure decreases. Two significantly different regimes of fuel-motion behavior were observed above and below a threshold designated as the threshold of gross fuel motion. Above the threshold, this motion occurs by molten fuel release. Below the threshold, fuel deforms plastically by a creep mechanism.
