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.”

Since MARC I in 1987, this series of conferences has become the major international forum for discussion of advances in radioanalytical chemistry and its applications, despite the somewhat remote location for many participants. A wide variety of topics are covered in the scientific program including environmental radioactivity measurements, activation analysis, biology and medical applications, radiation detectors and instrumentation, nuclear proliferation prevention and safeguards, education, and mass spectrometry methods for detecting radioactive materials.
