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.

A nuclear energy concept based on the integrated operation of a beam-driven hybrid fusion reactor and a companion fission reactor is investigated. The fuel for the fusion component is taken to be only deuterium, while the fissile fuel consists of the plentiful fertile nuclei 232Th or 238U. The different system features associated with various deuterium cycles are examined, and parametric reactor physics constraint relationships are established. It is concluded that the synergetic fusion-fission energy system described here displays very favorable energetic characteristics and, in addition, possesses the feature of total self-sufficiency with respect to fissile fuel supply.
