Powering the future: How the DOE is fueling nuclear fuel cycle research and development
As global interest in nuclear energy surges, the United States must remain at the forefront of research and development to ensure national energy security, advance nuclear technologies, and promote international cooperation on safety and nonproliferation. A crucial step in achieving this is analyzing how funding and resources are allocated to better understand how to direct future research and development. The Department of Energy has spearheaded this effort by funding hundreds of research projects across the country through the Nuclear Energy University Program (NEUP). This initiative has empowered dozens of universities to collaborate toward a nuclear-friendly future.

Using 14.7-MeV neutrons and gamma-ray spectroscopy with high-purity germanium detectors, the activation cross sections have been measured for the following nuclear reactions: (a) 44Ca(n,p)44K, = (39 ± 4) mb; (b) 44Ca(n,np)43K, = (3.0 ± 0.3) mb; (c) 44Ca(n,)41Ar, = (31 ± 3) mb; (d) 42Ca(n,p)42K, = (138 ± 12) mb; (e) 43Ca(n,p)43K, = (90 ± 9) mb; and (f) 48Ca(n,2n)47Ca, = (613 ± 60) mb. A 98.6% enriched 44Ca target was used for reactions (a), (b), and (c) and a natural calcium target for reactions (d), (e), and (f). These cross sections have been compared with some earlier published experimental values and with some results of calculations. The latter include those based on semiempirical formulas and those given by the preequilibrium plus compound-nucleus code GNASH. When applied to reactions (a), (d), (e), and (f), this code gives cross-section values that are consistently above the measured values.
