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 method for reprocessing uranium and plutonium mixed-oxide fuel, including uranium dioxide fuel, is presented. The method is based on the oxidation process of the fuel and the dissolution of pulverized fuels (U3O8 and PuO2) in nitric acid. To dissolve Pu02, a uranous nitrate solution prepared from uranyl nitrate by electrolytic reduction is utilized. This reprocessing method has an economic advantage over the conventional Purex process because it does not use an expensive solvent extraction process to separate uranium, plutonium, and fission products. The cost of the process is estimated to be 80% that of the Purex process, and the cost of refabrication does not change greatly because remote operation is not needed. This process also has an advantage over the Purex process from the viewpoint of the diversion resistance of nuclear material because pure plutonium cannot be recovered in the process.
