SC Nuclear Summit focuses on V.C. Summer
The second annual South Carolina Nuclear Summit held last week featured utility executives and legislators from the state, as well as leaders from Brookfield Asset Management, which is being considered to restart construction on the two abandoned reactors at the V.C. Summer nuclear power plant in Fairfield County. The summit, at the University of South Carolina’s Colonial Life Arena, attracted more than 350 attendees. The event was hosted by the university’s Molinaroli College of Engineering and Computing.

The 82.6 GHz/200 kW and 42 GHz/500 kW electron cyclotron resonance heating (ECRH) systems will be used in Tokamak SST-1 to carry out preionization and start-up experiments at 3.0- and 1.5-T operation. The 82.6-GHz gyrotron system has been tested for continuous waves (1000-s duration) using a conventional high-voltage power supply and for pulsed operation (200 kW for 1 s) using a regulated high-voltage power supply. The 42-GHz ECRH system is a pulsed system (500 ms), which will be used to carry out preionization and start-up experiments at 1.5 T (fundamental harmonic) on SST-1 and at 0.75 T (second harmonic) on Tokamak Aditya. The circular corrugated waveguide-based transmission line system contains two waveguide switches: one to test the gyrotron on a dummy load or the tokamak and the second switch to launch the ECRH power, either in SST-1 or in Aditya. The 42-GHz system has been tested on a dummy load, and the gyrotron delivers 500-kW power at beam voltage ∼49 kV and beam current ∼18 A. The output of the gyrotron is Gaussian (TEM00 mode) with mode purity >99%. The system is commissioned on both tokamaks (SST-1 and Aditya) to launch power in any tokamak.
