Task force charts growing interest in civilian maritime nuclear applications
Readers of Nuclear News will have heard of historical applications of civilian maritime nuclear power, like the merchant ship NS Savannah and the USS Sturgis floating power plant. With a few exceptions there has been little action in this area for over 50 years, and there are plenty of reasons and opinions as to why, but over the last few years the dramatic increase in interest from the maritime industry and its stakeholders has been undeniable.

The tritium trick technique was used to build-up radiogenic helium inside stainless steel 12Cr18Ni10Ti (SS). A great quantity of defects with a mean diameter of 20 nm, most probably platelet-like bubbles with 3He atoms, was observed in 3He-containing samples. The mean density of these bubbles in SS samples containing ~75 appm of 3He is estimated to be 61020 m-3. Much larger helium bubbles were observed in SS after annealing the samples at T1170 K. Thermal release of radiogenic helium occurs at T>1500 K. The presence of 3He in structural materials causes the formation of an additional state for hydrogen sorption.
