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.

In order to investigate the behavior of hydrogen isotope on the water-metal boundary, a series of deuterium permeation experiment from heavy water vessel through pure iron piping was performed as a function of temperature ranging 423~573 K at 15 MPa. During the experiment, the surface of iron piping was oxidized to magnetite at the heavy water boundary and then deuterium would generate by Schikorr reaction. This deuterium could be detected by mass spectrometer, which monitored the inside gases of the piping under vacuum. The result showed clearly that more than 85 % of the deuterium permeated through the metal piping and detected as deuterium gas (D2) under vacuum. The D2 permeation rate reached some stabilized value as a function of temperature.
