Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Ariz. governor vetoes “fast track” bill for nuclear
Gov. Katie Hobbs put the brakes on legislation that would have eliminated some of Arizona’s regulations and oversight of small modular reactors, technology that is largely under consideration by data centers and heavy industrial power users.

The neutron spectra on the central axis of a massive block of uranium depleted in the 235U isotope have been measured using spherical proton-recoil and 3He semiconductor-sandwich spectrometers. The experimental spectra are compared to calculated multigroup spectra obtained with a 208-group constant cross-section set which is based on KEDAK cross sections. By parametric variation of all relevant nuclear data, the sensitivity of the spectra to changes in the 238U cross sections is determined. The 238U capture and inelastic scattering cross sections are adjusted to bring the calculations in line with the experiment. It is shown that the resulting adjusted 238U cross sections also lead to considerably better agreement between experimental and theoretical results for other fast assemblies which are sensitive to changes in the 238U cross sections.
