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.

The thermal-neutron capture cross section and capture resonance integral for 243Cm have been measured in cobalt-monitored reactor irradiations of nearly isotopically pure 243Cm (99.94%) using cadmium filter techniques. The thermal-neutron absorption (capture plus fission) cross section and corresponding resonance integral for 243Cm have also been measured in a separate experiment relative to 248Cm. Values of σ2200(n, γ) = 130.7 ± 9.6, σ2200(n, f) = 609.6 ± 25.9, I(n, γ) = 214.7 ± 20.3, and I(n, f) = 1575 ± 136 b are reported.
