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.”

Results of global discharge modeling and simulation of the Hanbit magentic mirror discharge are given and an RF heating theory and its results are presented.
In the global discharge model, global transport equations of ions and electrons are solved including and impurity recycling equations. Based on the developed global model, the effect of oxygen impurity on the discharge characteristics is simulated. Also, Maxwell-Boltzmann equations are solved by the mode analysis technique to develop a theory of the radio frequency (RF) wave heating mechanism in a magnetic mirror discharge condition. Utilizing the solution the discharge impedance is calculated for the case of slot antenna. Moreover the plasma resistance is divided into an electron resistance and and ion resistance which indicate absorbed powers by electrons and ions, respectively.
