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.

Physical and chemical properties of tritium (T) and its oxides (T2O, DTO, HTO) were experimentally researched; hence, the following was identified: T to T2O conversion mechanisms due to radiation oxidation and isotope exchange in the T concentration range from 10E-8 to 600 Ci/1 in gaseous media of technological equipment (air, argon, hydrogen and their mixtures); diffusion, solubility, sorption and desorption constants of T and T2O in interaction process with structural materials of technological equipment (metals, polymers); properties of T oxidation catalysts (Pt, Pd, Ni, CuO, PdO) for various gas mixtures; properties of moisture adsorbents: synthetic molecular sieve, alumogel and silica gel at different T2O specific activity; mechanisms of waste formation: gaseous, liquid, solid - when T is operated on. Based on the accomplished research the following was developed: technical requirements to technological equipment and equipment units: boxes, containers, receivers, appliances; methods and devices to extract T and T2O from gases: absorbing elements, filters, gas cleaners; facilities for safe T storage in T2O adsorbed on sieve NaA with helium-3 extraction; technologies and devices to extract T and T2O from solid wastes as well as for liquid waste solidification. The developments implemented in the T items production have reduced personnel exposure doses by∼ 50 times and T-releases to the environment by∼200 times.
