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.

Since the 1950s, the U.S. government has developed and launched a number of space-based nuclear systems based on both decay of radioisotopes and fission. While private entities have supported the development and launch of nuclear payloads as contractors, the federal government funded and drove the development and operation of such systems. In recent years, the private sector has developed interest in leading the development, launch, and use of nuclear technologies for space applications. This growth mirrors similar trends toward commercialization in the space sector as a whole. This paper investigates that private sector interest in space nuclear systems based on interviews with over a dozen companies in the space and nuclear industries. It presents a definition of commercial space activities, develops a model for the commercial use of space nuclear systems, and explores the status of commercial space nuclear activities in the United States. Our research finds that private sector capabilities in developing, testing, and operating space nuclear systems are growing but require the development of advanced nuclear technology, growth and diversification of the space economy, and government regulatory action.
