ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

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 Soxhlet-type leaching test was carried out on borosilicate glass that contained 14 wt% simulated high-level waste. The morphology, texture, composition, and crystallography of the surface layers that formed were examined using optical microscopy, scanning electron microscopy, electron probe microanalysis, and analytical electron microscopy. Four surface layers, made up of 100- to 1000-Å crystalline and noncrystalline particles, formed on the glass. The elements found were classified into three groups based on their behavior in the surface layers. Group I contained the alkali metals, such as sodium, potassium, and cesium, which were strongly depleted from the layers as a result of leaching. Group II contained elements such as manganese, iron, nickel, zirconium, lanthanum, cerium, and neodymium, which were more concentrated in the surface layers than in the unleached part of the specimen, probably because the layers had shrunk during the drying process. Group III contained the elements which behaved inconsistently as a group: Some, such as calcium, silicon, and aluminum, were poor in the layers; magnesium and barium were present, but had concentration profiles that differed from those of Group II. Only one crystalline phase, a sheet silicate, formed in the layers. It had the expected chemical form, (Ca, Ba, La, Ce, Nd)x(Mn, Fe, Zr, Mg, Ni, Al)y(Si, Al)z(O, OH)m; its formation probably influenced the leaching mechanisms.
