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.

Using Monte Carlo methods the response matrix of a Bonner sphere spectrometer with a 6LiI scintillator has been calculated. The response functions were calculated for the bare detector and for polyethylene spheres 5.08, 7.62, 12.7, 20.32, 25.4, and 30.48 cm in diameter. Twenty-three beams of monoenergetic neutrons were used as sources in the energy interval from 0.025 eV to 100 MeV. The response functions were interpolated to energy points of those calculated in earlier literature works and compared with two response functions reported in the literature; good agreement was found from this comparison. The main differences were found for neutrons with energies higher than 20 MeV and, to a minor extent, for low-energy neutrons as well. These differences are mainly attributed to the cross-section libraries utilized in the different studies.
