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
Thermal Hydraulics
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 nuclear industry's current "vision" for 2020 is for growth in U.S. nuclear to a 23% share of generation in 2020. To support this vision, the Electric Power Research Institute's Nuclear Power Division has developed a strategic bridge plan. The major objectives of the plan are discussed. Of key importance is the U.S. Nuclear Regulatory Commission (NRC) staff's proposed framework for risk-informed regulations. RETRAN-3D will undoubtedly be used by the industry to support Risk-Informed Regulation, specifically option 3.The reason that RETRAN-3D is the most logical tool to support Risk-Informed Regulation is that in January 2001 the NRC issued a safety evaluation report (SER) on RETRAN-3D. The significance of the SER to the RETRAN community is described, and a list of the most important SER conditions provided.Next, the new and unique applications of RETRAN-3D are referenced. Finally, discussion of the future direction of safety software indicates what the author feels is needed to adequately support both existing plant upgrades and future plant designs.
