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.

We report the results of some calculations of the fundamental mode decay constant (and the corresponding eigenfunction) of the neutron transport operator in slabs and spheres of various sizes. The assemblies are assumed to be homogeneous and nonmultiplying with absorption cross section varying as 1/v. The scattering is assumed to be isotropic in the laboratory system, and parameters are chosen to represent the scattering by beryllium. The integral equations were solved by the multigroup technique, and calculations show that the fundamental mode eigenvalue for a slab is bounded by (v ∑)min whereas no bound exists for a spherical assembly. The solutions wherever possible are compared with the corresponding exp(iBx) theory results, and the implications for experiments are discussed. The nonseparability of the energy and space dependence of the asymptotic flux has been shown explicitly, and its consequences on the extrapolation distance have been pointed out.
