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 possible accidental releases from nuclear power plants with pressurized water reactors are classified into eight release categories. To assess the damage resulting from these releases, a model for accident consequences (UFOMOD) is set up. In this model, the atmospheric dispersion and ground deposition are evaluated, and the space- and time-dependent activity concentration in the atmosphere and on the ground is calculated. From these concentration values, the potential doses on which the different protective measures and countermeasures depend are first determined. The doses to be expected are then calculated taking into account these protective measures and countermeasures. Based on these doses, the consequences are assessed for the population affected, in terms of somatic early fatalities, somatic late fatalities, and genetic exposure. The consequences are then assessed by running several times through the 8 release categories at 19 sites with a total of 25 reactor units. The calculations for each site are based on 115 different weather sequences of several hours’ duration, assuming that these sequences have the same probability in each of the 36 predetermined wind directions (each of 10 deg). In parallel, the corresponding frequencies of occurrence are determined. From the pairs of values “extent of consequences/frequency of occurrence,” the final results are derived:
