New report lays out path to U.S. nuclear energy dominance
The new report “How America Can Achieve Nuclear Energy Dominance,” from the Working Group on U.S. Nuclear Energy Dominance, outlines a plan of action for the Trump administration that includes deploying new nuclear reactors, developing domestic supply chains, promoting nuclear exports, reforming regulations, and developing the workforce.
Working group chair Todd Abrajano said, “We welcome the Trump administration’s bold moves to kick-start the U.S. nuclear energy sector, but we recognize that President Trump’s executive orders alone can’t achieve our goals.”

The European Spallation Source (ESS) is currently under construction in Lund, Sweden. At the time of the first beam-on-target, foreseen in 2025, a first set of neutron scattering instruments will be commissioned, in addition to a test beamline for characterization of the source. For every planned beamline, all optics components will already have been installed in the monolith shielding surrounding the spallation target, but instruments will still be under construction in the neutron bunker area. Blocks of shielding, referred to as temporary beam stops or wall plugs, are then required to capture neutrons that will come out through the bunker wall feedthroughs during operation. This paper presents the results of parametric studies carried out to design temporary beam stops to assess the possibilities of reducing the weight and cost of such components and also to investigate the shielding efficiency of a wall plug as an alternative solution.
