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.”

An ECR plasma discharge device has been designed and operated to study plasma driven permeation initiated by a scrape-off plasma. The observed plasma parameters are ne: 1010/cm3 and Te: <5eV in the pressure (Po) range of 0.5 − 5 Pa. Protium and deuterium permeation through a SS 304 foil of 10 µm has been measured as functions of the pressure, bias voltage and the temperature of the sample foil. Even such a low temperature plasma, a typical plasma driven permeation was observed with a very sharp“spike” at the start point of the permeation. An evident mass effect was also observed in the permeation of hydrogen isotopes. At a low pressure, around 2 Pa, the permeation showed to depend on bias voltages applied to the tested sample foil.
