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 first results on plasma control with the new plasma control system of Tore Supra are described. The system has been especially designed for long-pulse operation: Plasmas are controlled by reference signals, which can be varied in real time by using diagnostic measurements. On-line determination of the global plasma equilibrium has enabled new operation scenarios in which both the power from the poloidal field generators and the total lower-hybrid (LH) power are used to control the plasma. Experiments with feedback control of the safety factor on the plasma boundary, control of the LH-driven current, control of the flux on the plasma boundary, and control of the internal inductance are demonstrated. Finally, future modifications to the system, aimed at controlling the current profile during long-pulse operation, are discussed.
