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 modified version of the LASER computer code is constructed by using Gear's method for isotopic burnup calculations. It is noted that the original version of the LASER code (as supplied recently by the Argonne Computer Code Center) errs in computation of 241Pu concentration due to a minor programming oversight. This error is corrected, and it is found that the corrected LASER and the modified LASER provide results that agree quite well. For the same calculations, the modified LASER requires only two-thirds the central processor unit time compared to the original (corrected) LASER (on an IBM 370/158). Also, the modified LASER has simpler and more general provisions for handling burnup calculations.
