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.

NEA panel on AI hosted at World Governments Summit
A panel on the potential of artificial intelligence to accelerate small modular reactors was held at the World Governments Summit (WGS) in February in Dubai, United Arab Emirates. The OECD Nuclear Energy Agency cohosted the event, which attracted leaders from developers, IT companies, regulators, and other experts.

Beryllium is used as an efficient neutron multiplier in several fusion reactor blanket designs. In the framework of the experimental research program on the neutronics of fusion reactor blanket designs established at the Institut für Reaktorentwicklung der Kernforschungsanlage Jülich GmbH, measurements of the neutron multiplication in beryllium produced by 14-MeV neutrons were carried out to check basic nuclear data. The measurements were made in rectangular geometry as a function of beryllium thicknesses of up to 20 cm. The experimental values of the neutron multiplication were found to be 25% lower than the calculated values for all thicknesses. The low value of the multiplication casts doubts as to the suitability of beryllium as a neutron multiplier in fusion reactor blankets to yield useful tritium breeding ratios.
