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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

A hypervapotron is an excellent candidate for single-side high heat flux removal (HHFR). Hypervapotron HHFR is accomplished by subcooled two-phase flow boiling and conjugate heat transfer involving efficient vapor generation, channeling, and condensation. To characterize additional optimal operating characteristics effectively using computational fluid dynamics (CFD) and/or experimental approaches (and/or design approaches), knowledge of the hypervapotron controlling parameters is essential for timely identification of enhancements to the HHFR configuration. To that end, three high heat flux–side controlling parameters and a characteristic temperature difference have been identified. These parameters include the effects of conjugate heat transfer, two-dimensional channel-wall dimensionless aspect ratios, and the characteristic temperature difference. Finally, these parameters may be useful in CFD (and experimental and/or design approaches) studies for optimizing HHFR and thermal protection in fusion and aerospace systems.
