DOE issues new NEPA rule and procedures—and accelerates DOME reactor testing
Meeting a deadline set in President Trump’s May 23 executive order “Reforming Nuclear Reactor Testing at the Department of Energy,” the DOE on June 30 updated information on its National Environmental Policy Act (NEPA) rulemaking and implementation procedures and published on its website an interim final rule that rescinds existing regulations alongside new implementing procedures.

Advanced Limiter Test II (ALT-II) is an axisymmetric toroidal belt pump limiter scheduled for installation on the TEXTOR tokamak in 1986. ALT-II consists of eight blade segments mounted on adjustable supports located 45° down from the outboard midplane of the torus. The passivelycooled pump limiter is designed to remove 5–10% of the plasma efflux and can withstand heat loads on its leading edges up to 300 W/cm2 for 3 second pulse durations. Engineering analyses for ALT-II include calculations of Lorentz forces that could arise during disruptions and predictions of thermal stresses in the blades. The blades are designed to withstand these conditions without compromising pumping efficiency. Support and drive mechanisms are being designed to operate reliably in TEXTOR with minimum introduction of impurities.
