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.

Beryllium is used as an efficient neutron multiplier in several fusion reactor blanket designs. In the framework of the experimental research program on the neutronics of fusion reactor blanket designs established at the Institut für Reaktorentwicklung der Kernforschungsanlage Jülich GmbH, measurements of the neutron multiplication in beryllium produced by 14-MeV neutrons were carried out to check basic nuclear data. The measurements were made in rectangular geometry as a function of beryllium thicknesses of up to 20 cm. The experimental values of the neutron multiplication were found to be 25% lower than the calculated values for all thicknesses. The low value of the multiplication casts doubts as to the suitability of beryllium as a neutron multiplier in fusion reactor blankets to yield useful tritium breeding ratios.
