Fusion energy: Progress, partnerships, and the path to deployment
Over the past decade, fusion energy has moved decisively from scientific aspiration toward a credible pathway to a new energy technology. Thanks to long-term federal support, we have significantly advanced our fundamental understanding of plasma physics—the behavior of the superheated gases at the heart of fusion devices. This knowledge will enable the creation and control of fusion fuel under conditions required for future power plants. Our progress is exemplified by breakthroughs at the National Ignition Facility and the Joint European Torus.

Neutron albedo methods can be used to simplify transport calculations in a wide variety of applications. Their utilization requires a collection of albedo data and a model which makes these results convenient for hand or machine computation. Results are presented here from neutron albedo calculations for incident intermediate-energy neutrons. These results can be explained using our knowledge of neutron interaction physics. Total albedos are directly related to the cross sections for elastic scatter and absorption. Angular distributions of reflected neutrons are approximately cosθr for all incident neutron conditions. The total albedo results are well modeled by an extension of a previously developed fast-neutron albedo model when ∑abs/∑t (the ratio of absorption to total cross section) is small.
