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 dynamic logical analytical methodology (DYLAM) modeling and analysis techniques are discussed, and its principal features are compared with those of the fault tree technique for reliability analysis. The study is performed with reference to the auxiliary feedwater system of a 1300-MW(electric) pressurized water reactor plant. The results reveal the advantages that can be obtained by modeling dynamic processes by DYLAM, especially when dealing with operator interventions in incident control and mitigation.
