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.

For kernels appearing in the system of integral equations for Legendre moments of the angular flux, we propose a factorized form that also accounts for the anisotropy of scattering and works in the original Euclidean space. The stationary problem in the above simplified mathematical formulation for monoenergetic neutrons is then solved by a DKPL technique, i.e., a suitable basis is defined, in terms of Legendre polynomials of the space variables, and the corresponding Fourier series development is adopted for the space distribution to reduce the system of integral equations for such unknowns to an algebraic system on the unknown coefficients of their Fourier series expansion inside the homogeneous parallelepiped. This expansion converges in the mean and point-wise uniformly to the exact solution. Both critical and subcritical physical situations are considered, and accurate numerical results for isotropic scattering are obtained.
