DOE announces NEPA exclusion for advanced reactors
The Department of Energy has announced that it is establishing a categorical exclusion for the application of National Environmental Policy Act (NEPA) procedures to the authorization, siting, construction, operation, reauthorization, and decommissioning of advanced nuclear reactors.
According to the DOE, this significant change, which goes into effect today, “is based on the experience of DOE and other federal agencies, current technologies, regulatory requirements, and accepted industry practice.”

The results of calculated and experimental studies of the influence of some parameters (the temperature and time of tritiation and aging, the cooling rate after tritiation) on the helium-3 concentration in metals are given. It has been experimentally found that the hydrogen concentration in [null]3 mm samples of 12Cr18Ni10Ti steel, which were saturated with hydrogen at 773 K and 50 MPa, makes up ~ 0.6 of the equilibrium hydrogen concentration immediately after cooling to room temperature and ~ 0.5 after 5000-hour aging.
