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 development of a parallel stochastic cellular automata model for neutron transport is presented. The model is derived from neutron physics and is implemented on a 2048 processor singleinstruction multiple-data architecture MasPar computer. Purely absorbing and purely fissioning onedimensional benchmarks are performed against analytical solutions. Favorable results from these two benchmarks motivated the performance of three other test cases. Results for a two-dimensional scattering-absorbing case and a one-dimensional time-dependent case compared fairly well qualitatively with literature results. Also, results from a one-dimensional, two-group case compared somewhat favorably, but the scheme used was deemed not efficient enough without modification.
