Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

Senate committee hears from energy secretary nominee Chris Wright
Wright
Chris Wright, president-elect Trump’s pick to lead the U.S. Department of Energy, spent hours today fielding questions from members of the U.S. Senate’s committee on Energy and Natural Resources.
During the hearing, Wright—who’s spent most of his career in fossil fuels—made comments in support of nuclear energy and efforts to expand domestic generation in the near future. Asked what actions he would take as energy secretary to improve the development and deployment of SMRs, Wright said: “It’s a big challenge, and I’m new to government, so I can’t list off the five levers I can pull. But (I’ve been in discussions) about how to make it easier to research, to invest, to build things. The DOE has land at some of its facilities that can be helpful in this regard.”

Neutron production from the D(d,np) reaction is investigated for projectile energies between 5.34 and 13.29 MeV, and for emission angles of up to 15 deg. The breakup spectral angular cross section is deduced from neutron time-of-flight measurements normalized to the well-established D(d,n)3He angular cross section. The energy-integrated neutron yield from breakup reactions strongly increases with the projectile energy, and it exceeds the yield of monoenergetic neutrons at projectile energies of ≈9 MeV for neutron emission in a forward direction. The angular distributions behave very similarly for both reactions up to laboratory angles of 10 deg. In addition, it is possible to describe the breakup spectra for emission angles up to 10 deg with only one distribution unique to each energy when normalizing the spectra to the maximum energy of the breakup neutrons.
