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 Case method is applied to the critical problem of a slab reactor with finite reflectors. The solution of the albedo problem is used to simplify the analysis of such a two-media problem. The expansion coefficient of the neutron angular flux of the core satisfies two coupled Fredholm integral equations in which some parameters and functions depend on the coefficients of the albedo problem. The approximate critical half-thickness and expansion coefficient are obtained by using the approximate result of the albedo problem.
