Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

The variations of ˜14-MeV (n, p), (n, ), and (n, 2n) reaction cross sections with A and Z have been analyzed. We tried to answer a rather interesting question: Can a simple parameterization be useful in comparing with nuclear reaction model calculations? In addition, we checked several approaches for parameterization. Simple systematics gave a better prediction than model calculation for the (n, 2n) reaction at A > 120. At a low mass number, the difference between experimental data and calculated or fitted results may be connected with the structure of levels for residual nuclei. We saw better agreement between experimental and fitted data in comparison with results of model calculation in particular for the (n, ) reaction for A < 110. Both approaches failed to predict (n, p) cross sections inside experimental uncertainties for A < 110 and the (n, ) cross section for A > 110. This failure may be connected with low accuracy of experimental data or with some unknown physical effect that provides an additional splitting of experimental data.
