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.

This month’s issue of Nuclear News focuses on supply and demand. The “supply” part of the story highlights nuclear’s continued success in providing electricity to the grid more than 90 percent of the time, while the “demand” part explores the seemingly insatiable appetite of hyperscale data centers for steady, carbon-free energy.
Technically, we are in the second year of our AI epiphany, the collective realization that Big Tech’s energy demands are so large that they cannot be met without a historic build-out of new generation capacity. Yet the enormity of it all still seems hard to grasp.
or the better part of two decades, U.S. electricity demand has been flat. Sure, we’ve seen annual fluctuations that correlate with weather patterns and the overall domestic economic performance, but the gigawatt-hours of electricity America consumed in 2021 are almost identical to our 2007 numbers.

This work aims to prepare a new series of polyepoxide resins reinforced with a mixture of WO3 and Bi2O3 compounds. The effect of replacing WO3 with by Bi2O3 on the radiation shielding parameters was experimentally evaluated using a NaI (Tl) detector and many radioactive sources, including 22Na, 133Ba, 137Cs, 60Co, and 152Eu. The linear attenuation coefficient for the prepared new polyepoxide-based composites was improved when substituting increasing amounts of WO3 with Bi2O3. When increased from 2.164 to 2.943 cm−1 (at 33 keV) and from 0.073 to 0.104 cm−1 (at 1332 keV), the Bi2O3 concentration in the prepared composites varied from 0 to 10 wt%, respectively. The substitution of WO3 with Bi2O3 greatly improved the shielding parameters of the fabricated composites. The half-value thickness, transmission factor, and lead-equivalent thickness were observed to decrease with increasing concentrations of Bi2O3 in the fabricated composites.
