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 neutron source characteristics of the Japan Atomic Energy Research Institute (JAERI)/U.S. Department of Energy collaborative program on fusion neutronics Phase-IIA and -IIB experiments are determined by measuring neutron spectra and various activation rates in the cavity and on the inner surface of the enclosure and the test regions. The analyses are performed by both JAERI and the United States using individual nuclear data and transport codes. The neutron spectra are generally well predicted by both Monte Carlo and Sn calculations in the energy range of 15 MeV to a few kilo-electron-volts, except for energies 10 to 1 MeV. The discrepancies between the measured and the calculated activation rates are within ±10% when recently evaluated nuclear data are used. Through the present investigation, the characteristics of incident neutrons in the test region can be satisfactorily predicted.
