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.

A 10-hp industrial motor with 12 yr of service in a commercial nuclear power plant and a 400-hp failed motor with >20 yr of service life in a nuclear research reactor facility were tested. The 10-hp motor was subjected to plug reverse cycling to induce accelerated aging while various insulation and bearing test parameters were monitored. Stator coils from the 400-hp motor were tested to diagnose age-related deterioration of insulation dielectric properties. The test objectives were to identify cost-effective motor testing methods or functional indicators that provide adequate feedback to detect degradation in motor components. It was found that monitoring and testing methods are available to detect degradation at an incipient stage. Therefore, implementing such methods in conjunction with plant maintenance activities should reduce catastrophic motor failures caused by aging and service wear in nuclear facilities.
