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.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

Amorphous hydrogenated carbon (a-C:H) is the nominal ablator to be used in French inertial confinement fusion (ICF) experiments. These capsules, containing the deuterium-tritium mixture, are developed for the LIL (Laser Integration Line) and the future Megajoule laser (LMJ) of the CEA. Coatings are prepared by glow discharge polymerization (GDP) with trans-2-butene and hydrogen. The films properties have been investigated. Laser fusion targets must have optimized characteristics : a diameter of about 1 mm for LIL targets and about 2.4 mm for LMJ targets, a thickness up to 175 μm, an outer and an inner roughness lower than 20 nm at high modes, a sphericity and a thickness concentricity better than 99%. This paper presents the first microshells obtained at the CEA with a GDP (Glow Discharge Polymerization) coater. Amorphous hydrogenated carbon shells of 175 μm with 1 mm or 2.4 mm diameter have been successfully prepared. The measured roughness at high modes is lower than 10 nm for a 30×30 μm characterization window.
