U.K. releases new plans to speed nuclear deployment
In an effort to revamp its nuclear sector and enable the buildout of new projects, the U.K. has unveiled a sweeping set of changes to project deployment. These changes, which are set to come into effect by the end of next year, will restructure the country’s regulatory and environmental approval framework and directly support new growth through various workforce efforts.

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.
