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.

Shielding of specific electronic components from the harsh bremsstrahlung environment expected on PBFA II has been investigated. 3-D Monte Carlo estimates of dose in locations throughout the facility have been compared with electronic technology thresholds to identify possible problem locations or technologies. In some parts of the facility, implementation of the 30-MV lithium ion diode option will increase dose rates to electronic equipment above tolerable levels. As a result, additional close-in shielding is being employed and some components are being moved to lower radiation level locations. None of the changes are prohibitive in terms of time, cost, or accelerator utility.
