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.

2024: The Year in Nuclear—July through September
Another calendar year has passed. Before heading too far into 2025, let’s look back at what happened in 2024 in the nuclear community. In today's post, compiled from Nuclear News and Nuclear Newswire are what we feel are the top nuclear news stories from July through September 2024.
Stay tuned for the top stories from the rest of the past year.

The resonance self-shielding effect of fission products on burnup characteristics has been investigated in high conversion light water reactors. Reactivity loss by burnup was considerably reduced by taking account of the self-shielding effects of fission products. The effect caused a difference of ∼0.6% for the multiplication factor at 50 GWd/tonne burnup and it contributed to a negative void reactivity. Furthermore, the mutual shielding effects of resonance overlapping among actinides and fission products have been examined and observed for several fission products. The effect of nuclear data uncertainties of fission products on the burnup reactivity change has been also examined by comparing the results obtained with four evaluated nuclear data files: JENDL-2, JEF-1, ENDF/B-IV, and -V. Fractional absorption rates for individual fission product nuclides were considerably scattered among these files. A significant difference between the reactivity changes calculated with JENDL-2 and ENDF/B-V was observed, while the discrepancy between those obtained with JENDL-2 and JEF-1 was small due to an accidental cancellation.
