The NRC’s Annie Caputo resigns
Caputo
Commissioner Annie Caputo is resigning from the Nuclear Regulatory Commission, according to a statement sent out to staff on Tuesday morning. Her resignation comes one day after the U.S. Senate voted to reconfirm chair David Wright to the commission.
“The time has come for me to more fully focus on my family,” Caputo said in her statement, provided by NRC spokesperson Scott Burnell. “I believe the [Trump] administration’s recent executive orders and the bipartisan ADVANCE Act have given the agency a platform for change.”

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.
