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.

A novel disc tubular reverse osmosis (DTRO) system was designed and applied for the removal of cesium ions from the simulated radioactive wastewater to enhance the concentration factor (CF), which is usually low with a conventional reverse osmosis system (about tenfold volume reduction). In this study, a three-stage structure was proposed to perform the decontamination and concentration separately for the radioactive wastewater treatment at different stages. This novel DTRO system makes it possible to achieve both high retention index (~99%) and CF (over 70) simultaneously. The system was operated at room temperature under ~4 MPa for stages I and II (permeate stages) and 6 to 8 MPa for stage III (concentrate stage). The wastewater processing capacity reached 450 ℓ/h, and only ~6 ℓ/h concentrate was produced. The DTRO system has the potential for application in the treatment of real radioactive wastewater produced in nuclear power plants.
