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 brief review is presented of the development and evaluation of coated-particle fuel for the Peach Bottom high-temperature gas-cooled reactor. The results of extensive thermal and irradiation tests on the Peach Bottom fuel materials have shown them to be adequate for a 3-yr core life of this reactor. Consideration of the mechanisms that could lead to coating failure under irradiation has shown that swelling of the carbide particle from fission-product accumulation and shrinkage of the pyrolytic-carbon coating from fast-neutron and fission-recoil effects are the principal contributors to coating failure. A “Triplex” pyrolytic-carbon coating has been developed to overcome these effects. This coating consists of a spongy layer of pyrolytic carbon overcoated with successive layers of laminar and columnar pyrolytic carbon.
