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.

In pool-type research reactors, a sudden loss of all pool water can result in significant external radiation dose. Of concern are fission product decay gamma rays emitted within the core, streaming out of the biological shield producing unacceptable radiation exposure in and around the reactor building. A Monte Carlo model was developed and used to generate dose maps for key access and traffic areas throughout the reactor facility at North Carolina State University. It was found that several of these areas could be exposed to significant gamma radiation fields, ranging from 230 rem/h 20 ft directly over and in line of sight of the core to 4 mrem/h outside and adjacent to the reactor building. Expected dose rates were also computed for the reactor bay floor, control room, and offices. The model was benchmarked against dose rates measured at the Lawrence Livermore National Laboratory pool-type reactor.
