Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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.

This study was conducted to develop improved treatment/disposal techniques for waste reactive metals. The basic approach considered was to convert the reactive metal (primarily sodium, with small quantities of radioactive and nonradioactive contaminants) to a glass form by reacting it primarily with silica sand, along with other minor additives to impart mechanical and chemical integrity to the waste form. A high-soda silicate glass was selected as the most desirable glass form for waste sodium disposal; however, it was found that small quantities of other additives would be necessary to impart acceptable resistance to leaching by groundwaters and other environmental stresses. Differential thermal analyses (DTA) with varying compositions of sodium oxide, silicon dioxide, calcium oxide, and magnesium oxide showed that the primary glass-forming reactions occur at <300°C. For the well-mixed samples used in the DTA tests, there were no additional thermal effects as the temperature was raised to 1260° C, indicating that the glass-forming reaction was essentially completed at the low temperature. Samples of different glasses were produced in a laboratory furnace to determine qualitative glass characteristics. Samples of sodium disilicate glass were tested for teachability of sodium by water. This particular glass had a relatively high sodium leach rate of 0.73 × 10−2 μg.mm−2.min−1 at room temperature in pure water. A conceptual one-step process for waste sodium conversion was designed, incorporating a low-g, low-pressure-drop, high-temperature cyclone as the reaction vessel as well as the reaction product separator.
