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 displacement behavior of hydrogen-deuterium at the high flow rate has been studied. The results show that displacement efficiency of deuterium decreases as displacement time decreases. Compared with the effects at low flow rate, high displacement efficiency still can be attained at high flow rate because higher displacement pressure that increases the collision frequency partly compensates the loss of exchange caused by an increase in flow rate.
