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 effects of the resaturation process occurring in the buffer on the analysis of temperature distribution in the engineered barrier system of a nuclear waste repository were assessed. The assessment was performed using the TOUGH2 computer code, which analyzes the multidimensional fluid and heat flows of the multiphase, multicomponent fluid mixture in an unsaturated medium. The hydraulic and thermal properties of the buffer, backfill, and near-field rock were measured and were used as input parameters for the analysis. If the resaturation process is considered in the thermal analysis, the disposal density of nuclear waste can be increased up to 30% under the given thermal constraint and site condition. The hydrostatic pressure in the near-field rock will not have an important impact on the resaturation process.
