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
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.”

Thomson scattering diagnostics has been updated to allow measurements at two instants of time for either of two spatial points in plasma during a single plasma discharge. Laser produces now two 15J laser pulses with variable (0.2–100s) delay between them. It was made possible by integration into previous laser system a second independent laser oscillator. Multichannel spectral measurements of scattered radiation can be accomplished at two spatial locations simultaneously, at z1 = 4m from the input of electron beam into plasma (old location) and at z2 = 2m (new location). Three geometries of measurement are possible: a single radial point at each of plasma cross-sections at z1 and z2 or two radial points at either cross-sections at z1 or z2. Number of radial points is limited by number of available detector channels (15ch) now. We present first experimental results with 90° detection of scattered radiation with upgraded system.
