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 preparative Gas Chromatographic (GC) system for the JET Active Gas Handling System (AGHS) can separate a daily throughput of up to 20 moles of hydrogen isotope gas mixture into the pure products of T2, D2, and H2 with very small interfractions in between. Design, assembly and special parts of the GC system, the various steps of the gas chromatographic process including safety aspects, control system and results of the inactive commissioning are presented. The GC system fulfils its specifications for isotope separation. We also describe a simple program to calculate the hydrogen isotope profiles in the columns of the GC system.
