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.

To measure the behavior of high energy ions, a semiconductor detector (named: ccHED) is installed at the central cell mid-plane of GAMMA 10. When ccHED is located at the radius of R=25cm from the center of plasma, the burst like signal is observed. To investigate this burst like signal, FFT method is applied to the signal of ccHED and signal of electrostatic probes (ESPs) which is used to measure fluctuations. As a result, it is clearly observed that the frequency component of the burst like signal has the same peak as one of the frequency components of the fluctuations. The amplitude of the signal has the pitch angle dependence. These observations suggest the existence of the radial transport of high energy ions due to the drift-type fluctuations.
