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
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.

The rate of sodium and potassium released from an alkali feldspar reacting with an aqueous solution varied with time. After an initial rapid exchange of alkalis for H+, dissolution rate decreased gradually, following in sequence, exponential, parabolic, and linear kinetics. Silicon was not released in the earlier stages but subsequently behaved very similarly to the alkalis. Aluminum behaved very similarly to the alkalis at the early stages but quickly reached saturation. Under an inert atmosphere, the pH of the solution was buffered at 8 to 10 after the initial sharp rise during the ion exchange stage. Dissolution occurred preferentially along crystal imperfections such as fractures, fluid inclusions, and grain boundaries rather than uniformly throughout the entire surface. The surface of a feldspar dissolved incongruently for the first few days of reaction but dissolved congruently thereafter. Clusters of precipitates occurred as discrete growths covering only small parts of the surface and were unlikely to retard dissolution.
