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.

Nuclear Power Plant Kalkar (SNR-300) | Fission Reactor | doi.org/10.13182/NT87-A15992

The sodium pumps, intermediate heat exchangers, and steam generators for the liquid-metal fast breeder reactor (LMFBR) SNR-300 were delivered by Neratoom and its industrial partners Royal Schelde and Stork Boilers. All main components were delivered to and erected in the plant between 1983 and 1985 after a long period of delay, caused mainly by continuously changing requirements with respect to the latest state-of-the-art construction and design. It is therefore concluded that to realize an effective manufacturing of breeder components an authorized and final specification is absolutely necessary. After the legal formalization of the licensing step Teilgenehmigung 7/5, it was hardly possible to further change the specification of the SNR-300 components. This led to a speeding up of manufacturing activities; the components were even completed ahead of the new schedules. Therefore, the procedure now foreseen for the post-SNR-LMFBR, to obtain a manufacturing license first before starting fabrication, should be regarded as the most important step toward a commercial LMFBR. The engineering work on the components was accompanied by extensive research and development (R&D) activities. Besides basic R&D work, all components were full-scale tested under SNR-300-like conditions in a 50-MW sodium test facility. The experiences gained from engineering, testing, and manufacturing of the Kalkar components can be used well in the design of the post-Kalkar SNR-2 plant.
