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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

Applications of wireless technologies in nuclear power plants (NPPs), in particular for monitoring purposes, have been gaining popularity recently. It has been shown that wireless technologies can offer several advantages over wired solutions. However, many challenges need to be overcome before widespread adoption of wireless systems in nuclear industries. This paper has extended the existing work in this area and has developed a systematic procedure to deploy a wireless sensor network within a NPP containment. The developed scheme deals with the following challenges explicitly: (a) restrictions on the peak transmission power of the wireless sensor modules, (b) workaround of large concrete and metal structures, and (c) avoidance of locations with high radiation levels. Starting from the sensor locations dictated by the variables to be measured, the scheme determines the positions of the wireless relaying modules in a three-dimensional containment space to ensure reliable data communication. The results from case studies under realistic NPP containment conditions demonstrate the practical value of the proposed solution.
