Ho Nieh nominated to the NRC
Nieh
President Trump recently nominated Ho Nieh for the role of commissioner in the Nuclear Regulatory Commission through the remainder of a term that will expire June 30, 2029.
Nieh has been the vice president of regulatory affairs at Southern Nuclear since 2021, though he is currently working as a loaned executive at the Institute of Nuclear Power Operations, where he has been for more than a year.
Nieh’s experience: Nieh started his career at the Knolls Atomic Power Laboratory, where he worked primarily as a nuclear plant engineer and contributed as a civilian instructor in the U.S. Navy’s Nuclear Power Program.
From there, he joined the NRC in 1997 as a project engineer. In more than 19 years of service at the organization, he served in a variety of key leadership roles, including division director of Reactor Projects, division director of Inspection and Regional Support, and director of the Office of Nuclear Reactor Regulation.

To reduce the cost of fast breeder reactor plants, advanced subsystem concepts are studied. The material quantities of the fuel handling system constituent subsystems are estimated and those with the largest quantities are selected for improvement. The advanced subsystem concepts studied include in-vessel fuel storage while cooling, an in-vessel fuel transfer machine with variable-reach arm, and a halfswing hinged-track fuel transfer machine. A significant reduction of overall system material quantity is promised by a suitable combination of the proposed advanced concepts.
