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.

An electromagnetic flowmeter (EMFM) has been used in the main cooling loop of the fast reactor, but the large-sized magnet structure of conventional EMFMs was not adopted. Therefore, it is necessary to develop a novel EMFM with small-sized magnets for the fast reactor. But the fear is that the decrease in the magnetic field and the end effect will make the EMFM’s performance worse, though there is no detailed information about the end effect due to such small-sized magnets. This paper describes the EMFM with small-sized magnets for coolant monitoring. By using three-dimensional steady-state electromagnetic analysis, we have studied numerically the end effect of an EMFM with saddle-shaped permanent magnets that are smaller in size than the pipe diameter. Consequently, it has been clarified that the performance of an EMFM can be improved by utilizing the effect of the downstream end of magnets and by combining the inclined electrodes and the effect of the circumferential ends of magnets.
