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.

The effect of long-term oxidation on the total hemispherical emissivity of Type 316L stainless steel (SS 316L) is of interest in nuclear plant safety and is reported on here. ASTM standard C835-06 [American Society for Testing and Materials, 2006] was used for measuring the total hemispherical emissivity of this material for the following surface conditions: (1) “as-received” from the manufacturer (essentially unoxidized) and (2) oxidized in air at 573 K for up to 3000 h. The emissivity of the as-received samples varied within the range from 0.24 at 434 K to 0.34 at 1026 K. Oxidation in air at 573 K for 500 h increased the emissivity range of the oxidized sample from 0.28 at 429 K to 0.38 at 1096 K. There was no further significant change in emissivity observed following an increase in the oxidation time from 500 to 3000 h. It is suspected that the emissivity ceased to increase during the additional oxidation time because of chromium oxide that formed on the SS 316L surface inhibiting further oxidation.
