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.

Nuclear waste: Trying again, with an approach that is flexible and vague
The Department of Energy has started over on the quest for a place to store used fuel. Its new goal, it says, is to foster a national conversation (although this might better be described as many local conversations) about a national problem that can only be solved at the local level with a “consent-based” approach. And while the department is touting the various milestones it has already reached on the way to an interim repository, the program is structured in a way that means its success will not be measurable for years.

Solubility of tritium in Cu-Be(2 mass%) alloy was determined by means of measurement of a tritium depth profile in the alloy. Tritium exposure to the samples was conducted under the following conditions: pressure, 0.4 to 2.6 kPa; temperature, 350 to 450°C; exposure time, 4 to 11 hours. Tritium depth profiles were obtained by chemical etching after the exposure. Remarkably high tritium concentration appeared in surface layers within 0.5 m, whereas almost constant concentration was observed from 10 m to the bulk. It was found, therefore, that surface tritium should be omitted in evaluation of the solubility of tritium. In addition, it was seen that dissolution of tritium into Cu-Be alloy obeys the Sieverts' law from the pressure dependence, and the solubility of tritium in Cu-Be alloy was lower than that in pure copper. From the temperature dependence of solubility, the heat of solution of tritium was determined as 17 kJ/mol.
