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.

A magnetron discharge was adopted in the inertial-electrostatic confinement (IEC) fusion device for drastic improvement of fusion reaction rate. With this discharge in the vicinity of the vacuum chamber, a substantial number of ions produced there are expected to have almost full energy corresponding to the applied voltage to the transparent IEC cathode under relatively low pressures compared with the conventional glow discharge. The magnetron discharge is found to occur even for the pressure of 0.07 mTorr (H2) in the present configuration of the experiment, compared with 5 mTorr in the glow discharge.
