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.

IEA report: Challenges need to be resolved to support global nuclear energy growth
The International Energy Agency published a new report this month outlining how continued innovation, government support, and new business models can unleash nuclear power expansion worldwide.
The Path to a New Era for Nuclear Energy report “reviews the status of nuclear energy around the world and explores risks related to policies, construction, and financing.”

A procedure for calculating the neutron multiplication factor and few-group constants for water-moderated reactors has been developed. The intent of this development was to produce a calculational procedure which could be used with confidence in the engineering design of water-moderated reactors. Analytic procedures that require large amounts of computer time were excluded from consideration. The proposed procedure includes a heterogeneous treatment of the fast-fission effect, resonance absorptions and the thermal utilization. The results of the procedure agree well with more rigorous calculations requiring orders of magnitude more computer time. The procedures have been applied to 116 U-metal and UO2 experimental lattices covering a wide range of parameters. The multiplication factor is calculated for all cases with a standard deviation about the mean of 0.86%.
