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 supercritical helium (SHE) circulation pump, a jet pump, and a cold compressor were designed and manufactured as the first step of cryogenic component development for a large-scale cryogenic system which is required for the Fusion Experimental Reactor (FER). The SHE circulation pump achieved 320-g/s flow rate with an 0.08-MPa pressure head at 4.6 K, making it the biggest cold pump in the world. The jet pump's mass flow ratio was about 1.0 with an 0.07-MPa pressure head at about 10 K. The cold compressor was successfully operated with an inlet vapor pressure of 0.053 MPa (3.7 K) , and outlet pressure of 0.12 MPa, and a mass flow rate of 60 g/s. The designs and test results are described in this paper.
