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.

On the basis of the principle of gas ionization, a simple, compact and portable surface activity monitor for tritium has been conceived. Theoretical analysis suggest that the ionization surface activity monitor would have a sensitivity of about 74 Bq cm−2, this sensitivity value having being determined for a measurement surface area of 1 cm2 and current measurement limit of 1 fA. Experimentally, several proof of principle tests have been carried out demonstrating the validity and viability of the ionization surface activity monitor. The results show that the ionization surface activity monitor is a simple, direct and effective tool for the measurement of tritium activity on surfaces and in the near surface regions.
