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.

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.”

Monte Carlo calculations have been carried out in great detail on the reflection properties of concrete for fast neutrons. This paper presents the results for the differential angular dose albedo for various incident-beam conditions and touches upon some of the other distributions calculated. The following formula is offered to represent the calculated differential angular dose albedo to better than 10% for about 95% of the values obtained, and which can be used to extend the results to the entire hemispherical range for both incident and reflected neutron velocity vectors:
