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.
International High-Level Radioactive Waste Management Conference

UNF-ST&DARDS is being developed to provide the ability to perform automated analysis of spent nuclear fuel (SNF) storage, transportation, and disposal systems. UNF-ST&DARDS provides a database for storing and preserving SNF data and streamlines various analyses using the data from the database for time-dependent characterization of SNF and related systems (e.g., dry storage system). UNF-ST&DARDS allows for modelling the variation of cask payload burnup, enrichments, and cooling times through a flexible GUI. This tutorial will include 1) discussions on various data need for realistic SNF characterizations and demonstration of the data import processes in UNF-ST&DARDS, 2) assembly-specific, time-dependent depletion and decay analyses, 3) as-loaded (using actual cask loading maps) criticality and shielding analyses of currently loaded casks for storage, transportation, and disposal (over disposal time periods), 4) discussion of as-loaded analyses to support licensing/certification of dry SNF systems, 5) misload analysis methodology to support as-loaded criticality analysis, 6) design-basis criticality and shielding analyses using user-defined loading patterns and fuel assembly types, and 7) dry storage loading optimization using UNF-ST&DARDS. The tutorial/demonstration is open to all registered meeting attendees who signed up at the time of registration. Attendees have no requirements to watch the demonstration, however, an RSICC license for UNF-ST&DARDS and SCALE is necessary if they would like to follow along.
