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.

An ICRF antenna for 6 MW RF power coupling to plasmas has been developed. For long pulse (300 s) and high power operation, the antenna has many cooling channels inside the current strap, Faraday shield, cavity wall and vacuum transmission line to remove the dissipated RF power and incoming plasma heat loads. The RF power test has been performed to ascertain the voltage and current limits of the antenna at the frequency of 30 MHz. During the RF pulse, the peak voltage, forward/reflected powers, temperature on the cavity wall, and gas pressure are measured. Results show the peak voltage of 33.2 kVp for 60 s and 25.2 kVp for 300 s (without cooling).
