ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

New experimental results on the vapor pressure of UO2 up to extremely high temperatures have recently become available. These vapor pressure data, obtained by advanced experimental techniques, are lower than the ones used thus far at Kernforschungszentrum Karlsruhe. It was, therefore, appropriate to carry out a completely new evaluation of the equation of state (EOS) of UO2- Eyring’s significant structures theory, which was extended to the case of nonstoichiometric urania, was applied for this work. The extended theory is described in some detail. By a suitable choice of the model parameters, good agreement of the evaluated EOS with recent experimental data was obtained, which is additional evidence of the reliability and consistency of the recent data. The extrapolation predicts a critical temperature of 10 600 K, which is higher than earlier predictions.
