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.

The operators of nuclear power plants are generally trained to handle a standardized set of typical accidents. This set is designed to define a package containing the event combinations that might be hypothesized. Because of the large number of hypothetical events, diagnostic ability requires continuous training. The development of, and experience with, a flexible training device is described that basically presents realtime scenarios. It could be shown that even complex events can be displayed successfully. Real plant transients as well as those calculated with sophisticated computer codes can be displayed. Test sessions with responsible technical personnel at reactor plants in the Federal Republic of Germany demonstrated the capabilities of the system.
