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.

Calculated results have been obtained of the uncertainties in the neutron scalar flux, the energy deposition per unit volume, and the displacements per atom in the toroidal field coil of a tokamak experimental power reactor due to neutron cross-section errors in iron and carbon, which are major constituents of the blanket-shield-coil configuration considered. The calculations were carried out using perturbation theory to obtain sensitivity profiles for the various cross sections of interest, and these profiles were then combined with cross-section error estimates, including correlations, to obtain the uncertainties. Each of the three responses—the neutron scalar flux, the energy deposition per unit volume, and the displacements per atom—is found to be very sensitive to the cross sections in the energy group that contains the source (∼2.2 pJ) since a deuterium-tritium source is assumed, and each of the responses is found to have a relative standard deviation of ∼100% due to neutron cross-section errors in iron.
