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.

Reactivity effects associated with the mitigation of unprotected loss of flow in sodium fast reactors are being studied to find ways to reduce the potential release of mechanical energy.The studies performed with ERANOS illustrate the importance of cladding removal as well as radial leakage changes during the core slumpdown. Possible arrangements and dispositions are envisioned that would avoid recriticality and hence the possibility of going into severe power excursions.Challenges to be faced by safety studies that would ascertain that no cliff-edge effects occur are then listed.
