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 retention of 131 I by a deep bed carbon filter (adsorber) of an FRG pressurized water reactor under normal conditions was determined with different test methods. These comprised (a) in-place tests on the carbon filter with CH3I3II and 131 I from the plant (contained in the exhaust air) and (b) laboratory tests on carbon samples with CH3131I. The laboratory tests with CH3131I produced results that were not conservative with respect to the organic 131I from the plant because of the occurrence of more penetrating organic 131I species in small proportions (<10%).
