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 University of Rochester Laboratory for Laser Energetics Laser Direct-Drive 100-Gbar Campaign requires fuel capsules with specified limits on the number of localized surface defects in the 0.1- to 1-µm range. Schafer Livermore Laboratory has applied techniques of bright-field conventional imaging and charge-coupled-device–based dark-field microscopy as a possible method of characterizing the number and sizes of local particle-like defects on these capsules. Through simple experiments, we are able to correlate measured localized light-scattering levels with sizes of spherical polystyrene test particles. We have developed an engineering concept for whole-surface capsule scans based on quantitative dark-field microscopy as well as conventional imaging microscopy. This system and technique will be particularly useful during capsule development and capsule handling (transport, assembly, etc.) investigations.
