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 regenerative process involving the use of a dilute solution of nitric (0.5 to 1.0 wt%) and hydrofluoric (0.05 wt%) acids was developed for decontaminating stainless steels (Type 304) to release limits. The solution is regenerated using a strong acid cation exchanger and may eventually be disposed of after processing through a strong base anion exchanger. The waste management aspect of the decontamination is thus limited to the disposal of relatively small volumes of spent cation and anion exchange resins. Application of the acidic reagent for 1 hat 95°C to the tray surfaces of an obsolete irradiated fuel storage basket from Pickering Nuclear Generating Station resulted in the removal of metal exceeding 1 µm and a residual (β,γ) contamination below a target limit of 0.1 µCi/m2. A soak tank system with associated purification, vapor handling, and auxiliary systems is proposed for performing full-scale decontaminations of the baskets.
