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.”

A new type of fast neutron spectrometer composed of a proportional counter with methane and a Si semiconductor detector was constructed for the measurement of plasma-temperature. Methane can act as recoil-proton converter and also as energy loss measurement of the proton in the converter. Si detector, off-centered to avoid radiation damage, measures the rest energy of the recoil-proton. The energy resolutions were 2.4 % for 5 MeV neutrons and 2.9 % for 14 MeV neutrons.
