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.

Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

The degradation products produced in Purex solvent by exposure to nitric acid and radiation can be divided into two groups: those that are removed by scrubbing with sodium carbonate solutions and those that are not; the latter materials are called long-chain degradation products. This paper describes investigations using activated alumina for removal of these long-chain degradation products from first-cycle, Savannah River Plant and Idaho Chemical Processing Plant solvents that had been previously washed with sodium carbonate solution. Activated alumina was found to be very effective for improving the phase separation of the solvent from the sodium carbonate solutions, increasing the interfacial tension, and removing components that complex plutonium. It was less effective for removing anionic surfactants and ruthenium. The capacity of the activated alumina for treating 30% tri-n-butyl phosphate solutions was greatly improved by drying the solvent before treatment.
