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.

The Superphénix-2 (SPX-2) core is presented with an explanation of the choice of the main options. The SPX-2 core delivers a total power 20% higher than SPX-1 in a reactor vessel of almost the same size, including internal storage of the burned fuel, which is specific to SPX-2. This leads to a drastic reduction in the capital cost of the reactor, which is accompanied by a strong reduction in the cycle cost due to improvements in the fuel burnup. Some specific core problems are described, such as shutdown requirements for control rods, fuel management, start-up core, and core monitoring systems, where the increased burnup and the simplified overall reactor design require modifications from SPX-1.
