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.

In August 2020 a derecho hit Duane Arnold head on causing a loss of offsite power lasting about 24 hours. Winds speeds exceeded 80 mph for over 20 minutes with peak speeds exceeding 100 mph. A complication was debris fouling of service water pump suction strainers requiring bypassing one of the strainers. This session will describe what happened to the plant, how the plant successfully dealt with the event including site preparations, response and what could have been improved. In addition, the session will explore the risk insights gained on both Duane Arnold and other plants.
