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.

Post-irradiation examination (PIE) of a low-enriched-uranium silicide fuel plate, irradiated in the Indonesian Reaktor Serba Guna–Gerrit Augustinus Siwabessy (RSG-GAS) multipurpose reactor, was successfully conducted. The objective of the PIE project was to evaluate the performance and integrity of the fuel under radiation exposure and, furthermore, to explore the potential for increasing the burnup level, enhancing its efficiency and effectiveness. The targeted fuel plate, identified as IDA0045, was extracted from the experimental silicide fuel element RI-SIE2, which had a burnup level of approximately 56% loss of 235U. A scanning electron microscope combined with energy dispersive X-ray spectroscopy microstructural examination and a Vickers microhardness test were conducted for the top, middle, and bottom sections of the fuel. The PIE results indicated minimal occurrence of fuel swelling and good fuel integrity under irradiation, suggesting the possibility of increasing the burnup level.
