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 source range monitor (SRM) response during the first 25 h of the Three Mile Island Unit 2 (TMI-2) accident is analyzed. The response of the SRM was simulated by performing static neutron transport calculations on a variety of lower head core material distribution models. Using the previously derived core and lower head material configurations at 225 min and 3 yr after shutdown as starting points, the changing lower head material distribution during the period from 225 min to 25 h after shutdown was estimated. The estimated lower head material distribution derived from this transport analysis appears to be consistent with other studies performed under the auspices of the TMI-2 accident evaluation program.
