Modernizing I&C for operations and maintenance, one phase at a time
The two reactors at Dominion Energy’s Surry plant are among the oldest in the U.S. nuclear fleet. Yet when the plant celebrated its 50th anniversary in 2023, staff could raise a toast to the future. Surry was one of the first plants to file a subsequent license renewal (SLR) application, and in May 2021, it became official: the plant was licensed to operate for a full 80 years, extending its reactors’ lifespans into 2052 and 2053.

Thomson scattering (TS) is the most reliable diagnostic to measure the electron temperature and electron density radial profiles. In GAMMA 10, the yttrium-aluminium-garnet (YAG)-TS system was constructed with the large solid angle of TS collection optics. We carried out the Rayleigh and Raman scattering experiments for system settings and applied the YAG-TS system to the GAMMA 10 plasma. We can successfully measure the electron temperature and density radial profiles in the central cell of GAMMA 10 by using YAG-TS system. The supersonic molecular beam injection (SMBI) experiments have been started for plasma fueling study in GAMMA 10. In SMBI experiments, we observed the electron temperature decrease and electron density increase in the plasma center.
