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 10B(n,αγ)7Li relative cross section has been measured using the 200-m flight path of the National Bureau of Standards Linac neutron time-of-flight facility. Results are presented from 5 to 700 keV, showing the 5/2- level of 11B at 500 keV. The neutron flux was monitored with a hydrogen proportional counter. The known n-p scattering cross section was then used to normalize the data to obtain a relative cross section. No attempt was made to obtain an absolute normalization experimentally. Overall accuracy is estimated to be better than 3% from 10 to 400 keV.
