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.

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.

The authors describe the criticality and reactivity measurement method (CRMM) and give results of their analysis obtained by using this method for a physical inventory of nuclear materials (NMs) on the Nartsiss critical assembly at the Russian Research Center Kurchatov Institute (RRC KI). The proposed approach is a further development of the criticality measurement method used at the Los Alamos National Laboratory (LANL), and is a joint effort of LANL and RRC KI. A brief description is given of the Nartsiss critical assembly. Statistical control charts are used to study the reproducibility of results. The contributions of individual components to the resultant error of the proposed method are estimated. The method of quantile estimates of random errors is used in error analysis. It is shown that the CRMM has high sensitivity and may be successfully used in NM control and accountability.
