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.

Understanding the reason for the divertor flow asymmetry in heliotron/torsatron-type fusion devices is important for the safety of the in-vessel components, such as divertor plates subject to the direct impact of the plasma or the electrical probes and thermocouples for measurements of the particle and energy fluxes to the divertor plates. In previous work, the divertor flow distributions were studied mainly with focusing on the up-down asymmetry in a heliotron-type fusion device, Heliotron E. This paper analyzes the in-out asymmetry of divertor flows and discusses the effects on this asymmetry of the magnetic axis position (the horizontal shift due to variation of the vertical magnetic field or plasma pressure) and power of neutral beams.
