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.

The Experimental Advanced Superconducting Tokamak (EAST) was built to demonstrate high power, long pulse operation under fusion relevant conditions, and provide a viable platform for next-step steady-state magnetic confinement fusion development. Significant progress has been made in EAST on both technology and physics fronts, achieving full plasma current of 1 MA, long pulse operation over 400 s, entirely driven by Lower Hybrid Current Drive (LHCD), and high confinement plasmas, i.e., H-modes, over 30 s with combined operation of LHCD and Ion Cyclotron Resonant Heating (ICRH). New and exciting physics with dominant RF heating has started to emerge, as evidenced by new findings on LHCD-induced 3D edge magnetic topology, new small Edge Localized Mode (ELM) regime and role of zonal flows during the L-H transition, etc. Various means for mitigating ELMs have also been explored to facilitate long pulse operation, including SMBI, D2 pellet injection, as well as innovative solid Li granule injection. A brief overview of these recent advances is presented.
