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.

The development of pressurized water reactors and boiling water reactors in the world necessitates complete critical experiments on this type of fuel for the validation of the methods used in criticality calculations and to resolve the various related problems. This paper presents the first results obtained at the Critical Mass Laboratory at Valduc during critical approaches achieved with lattices of 4.75-wt%-235U-enriched UO2 rods in water. Four square pitches (12.6, 16.0, 21.0, and 25.2 mm) and three triangular pitches (13.5, 17.2, and 22.6 mm) have been studied, and various configurations with fuel rods removed were investigated. Benchmark calculations are presented.
