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.
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

The consequences of closure: The local cost of shutting down a nuclear power plant
When on May 7, 2013, the Kewaunee nuclear power plant in rural Wisconsin was shut down, it took with it more than 600 full-time jobs and more than $70 million in lost wages, not including temporary employment from refueling and maintenance outages. Taking into account indirect business-to-business activity, the total economic impact of the closure of the single-unit pressurized water reactor was estimated to be more than $630 million to the surrounding three-county area.

We developed a cross-section adjustment method based on Bayesian theory for adjusting the independent cross-section set that is given by dividing the cross-section set. While all cross sections have to be adjusted in the conventional cross-section adjustment method, the independent cross-section set can be individually adjusted in the developed method. In addition, the covariance of cross sections that are assumed to be independent of each other is not adjusted in the developed method. The adjusted cross sections and the covariance are the same in both methods. The cross-section adjustment was performed using the criticality of the light water–moderated uranium benchmark. The result shows that the uncertainty of the multiplication factor is reduced from 0.005 to 0.007 Δk/k to 0.003 to 0.005 Δk/k by the developed method. The reduction is smaller than that by the conventional method since the developed method does not adjust the covariance of cross sections that are assumed to be independent of each other.
