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
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

The Abnormal Occurrences Reporting System (AORS) of the Commission of the European Communities is a data bank that contains homogenized information on safety-related events that have occurred in nuclear power plants in Europe and the United States, covering ∼780 yr of total reactor operation from 1969 to 1985. The use and analysis potential of this information system are illustrated, particularly with respect to the support it gives to incident analysts and probabilistic safety assessment (PSA) practitioners. As an example, attention is focused on a particular methodology for using the incident data during the modeling stage of a PSA study, or more generally, in the course of any type of incident analysis. In this case, a sophisticated multistep retrieval procedure identifies a set of event reports from the data bank, of which the (possible) relationship is unknown a priori, but which are brought together under the attention of the analyst. Seen together within the framework of the study in hand, these reports might yield valuable information for upgrading the completeness of the system, subsystem, and component models in terms of failure modes and effects, fault propagation paths, and unforeseen system interactions. This semiautomatic procedure exploits a feature that renders the AORS unique among international safety-related event data bases, namely, the codification and storage of causal sequences extracted from each event report.
