Senate EPW Committee to hold Nieh nomination hearing
Nieh
The Senate Environment and Public Works Committee will hold a nomination hearing Wednesday for Ho Nieh, President Donald Trump’s nominee to serve as commission at the Nuclear Regulatory Commission.
Trump nominated Nieh on July 30 to serve as NRC commissioner the remainder of a term that will expire June 30, 2029, as Nuclear NewsWire previously reported.
Nieh has been vice president of regulatory affairs at Southern Nuclear since 2021, though since June 2024 he has been at the Institute of Nuclear Power Operations as a loaned executive.
A return to the NRC: If confirmed by the Senate, Nieh would be returning to the NRC after three previous stints totaling nearly 20 years.

A disk tubular reverse osmosis (DTRO) membrane system was designed and applied for the treatment of radioactive wastewater produced in a high-temperature gas-cooled reactor (HTGR) in pilot scale. The pretreatment system was simplified using a cartridge filter. A three-stage membrane system was researched and developed. The performance of the DTRO system was examined using surrogate wastewater. The volume reduction factor of the system reached 50, and the decontamination factor reached 5760. The membrane system was designed to operate at high flows. When wastewater was pumped into the membrane system, the high-speed flow of the influent prevented the fouling of the membrane. The operational performance to treat low- and intermediate-level radioactive wastewater was examined. The membrane system can be used to treat the wastewater from HTGR.
