Ho Nieh nominated to the NRC
Nieh
President Trump recently nominated Ho Nieh for the role of commissioner in the Nuclear Regulatory Commission through the remainder of a term that will expire June 30, 2029.
Nieh has been the vice president of regulatory affairs at Southern Nuclear since 2021, though he is currently working as a loaned executive at the Institute of Nuclear Power Operations, where he has been for more than a year.
Nieh’s experience: Nieh started his career at the Knolls Atomic Power Laboratory, where he worked primarily as a nuclear plant engineer and contributed as a civilian instructor in the U.S. Navy’s Nuclear Power Program.
From there, he joined the NRC in 1997 as a project engineer. In more than 19 years of service at the organization, he served in a variety of key leadership roles, including division director of Reactor Projects, division director of Inspection and Regional Support, and director of the Office of Nuclear Reactor Regulation.

The Atmosphere Detritiation System (ADS) for ITER is being designed to provide the required cleanup of tritium spills into the building and into inert atmospheres for the lowest cost while meeting required emission regulations and limits. Since the CDA phase, changes in the reactor and building design, a new containment philosophy and vacuum vessel maintenance requirements have resulted in adoption of modular designs of the ADS. This paper describes how the different conditions were implemented in hardware and why the number of ADS modules of the present ITER are less than those specified during the CDA phase. The paper will also indicate how volume reduction features of technologies such as membrane humidity-air separators, could be used in ADS if sufficiently developed. The application of low inventory molecular sieves and hydrophobic catalysts will also be considered.
