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.

Three applications of the RETRAN code at Florida Power & Light Company (FPL) to enhance plant operational margin and support training simulators are presented. Two of the applications are intended to increase plant availability, one by reducing the frequency of unnecessary reactor trips on turbine trips during power ascension and the other by providing a simple relationship between electrical frequency and reactor coolant flow. This relationship is then used in selecting electrical load-shedding schemes. The third application is in the area of training simulators, where special RETRAN best-estimate analyses have been used as part of the acceptance testing program for the FPL simulators.
