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.

NRC v. Texas: Supreme Court weighs challenge to NRC authority in spent fuel storage case
The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.

The thermal conductivity of PuO2 as determined by thermal diffusivity measurements is presented for the temperature range 250 to ≈1200°C. Specimens of PuO2 with confirmed stoichiometry were fabricated by hot isostatic pressing of powder to densities of 96.5 and 81.9% of theoretical. The thermal diffusivity of four specimens, two of each density, was measured by the heat pulse technique using a laser as the heat source. The data indicated that the thermal conductivity of PuO2 is lower than that of UO2, and decreases with increasing temperature from 250 to 1000°C in an approximate 1/T relation. Values range from 0.06 W/(cm deg C) at 300°C to 0.025 W/(cm deg C) at 1200°C. An apparent reduction of the PuO2 was observed at temperatures above 1200°C.
