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.

Some variations and extensions of a Fuel Cleanup System based on the combination of palladium diffuser and a vapor electrolysis cell were studied to improve the flexibility to accept broader range of flow rate, gas contents and operation modes. Processing of inert gas - CH4, H2, He2O mixtures in a closed loop showed satisfactory detritiation, with the processing of methane by catalytic steam reforming and oxidation, and electrolytic oxidation. The decomposition of hydrocarbon on the anode side of the ceramic electrolysis cell was tested to study the feasibility as an oxidizer. The zirconia ceramic membrane with Pt electrode are tested with methane at the anode for oxidation, and water vapor on the cathode for reduction. The cell converted methane to carbon dioxide and vapor with high efficiency and simultaneously decomposed water vapor to hydrogen. This application of the cell simplifies the process, and eliminates the use of catalyst and oxygen gas. A versatile fuel cleanup that eliminates most of previos concerns and improves the performance is proposed.
