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 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. 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.”

Transient MHD activity in the multiple-mirror trap GOL-3 at the stage of plasma cooling after decay of the net current was studied. Such events are diagnosed as short bursts (generally shorter than 5 cycles) of oscillations of azimuthal magnetic field with the frequency within 0.1 [divided by] 1 MHz. Earlier transient events at the plasma decay stage were also observed. At that time an existence of long-lived internal current structures in the GOL-3 plasma was supposed.The paper presents new results from the magnetic diagnostics. Azimuthal and longitudinal mode localization agrees with the assumption that the magnetic field is generated by filaments with the current in the range of 1 [divided by] 50 A in nearly uniform azimuthal distribution. Statistical analysis shows that the main oscillation frequencies are grouped near the inversed time of the Alfven wave propagation along the trap. Power dependence of the pulse probability on its amplitude with the index = -1.87 was found. Relationships of MHD activity on the regime of plasma heating and on a degree of the beam stabilization at the exit receiver are discussed.
