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
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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.

When a propagating neutron wave reaches an interface between two media, a part of it is transmitted and a part is reflected. In the present work, neutron waves reflected from the core and from the reflector are compared. The following is concluded: Reflection exists in both cases. When the first medium in which the wave is propagating is a multiplying medium, it is much easier to detect the reflected wave than it is in the nonmultiplying diffusive medium. The reflected wave amplitude and phase depend much more on the properties of the first medium than on the properties of the reflecting medium. Neutron waves reflected back into the core are in phase with the propagating waves and hence reinforce them. Neutron waves reflected by the core are out of phase with the propagating waves and hence weaken them. Other characteristics of the amplitudes and phases of waves in both cases are compared.
