DOE announces NEPA exclusion for advanced reactors
The Department of Energy has announced that it is establishing a categorical exclusion for the application of National Environmental Policy Act (NEPA) procedures to the authorization, siting, construction, operation, reauthorization, and decommissioning of advanced nuclear reactors.
According to the DOE, this significant change, which goes into effect today, “is based on the experience of DOE and other federal agencies, current technologies, regulatory requirements, and accepted industry practice.”

Amorphous hydrogenated carbon films are the nominal ablators to be used in French inertial confinement fusion (ICF) experiments. These targets are developed for the future Megajoule laser (LMJ) of the CEA. Coatings are prepared by remote rf-PECVD and their properties have been investigated. Laser fusion targets must have optimized optical characteristics (UV-visible transparency), mechanical strength, high gas permeability, low oxygen pollution. The films are characterized by 13C NMR, RBS, UV-visible spectroscopy, gas permeation, thermogravimetric analysis. A study of the glow discharge is also developed using optical emission spectroscopy and mass spectrometry. In this article, we try to understand the relationships between precursors, plasma composition, deposition rate and film properties.Best results are obtained with trans-2-butene/hydrogen (T2B/H2) coatings in post-discharge.
