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 diffusion coefficient for plutonium diffusing in isotropic pyrolytic carbon has been determined as a function of temperature. The apparent diffusion coefficient can be expressed by the equation D = 4.47 × 10’−8 exp(−55 0001R T) m2· s−1over the temperature range from 1273 to 2073 K. Evaluation and comparison of the plutonium diffusion data with that of uranium and thorium using a compensation law treatment resulted in a reasonably good correlation, thus implying similar diffusion mechanisms.
