Ho Nieh, TVA board members, and nuclear fuel recycling bill head to Senate floor
Nieh
Ho Nieh, the Trump administration’s nominee to be a member of the Nuclear Regulatory Commission, and four new board members of the Tennessee Valley Authority were approved in a vote today by the Senate Environment and Public Works Committee and head to the Senate floor for a final vote.
The committee also voted to advance to the Senate floor the Nuclear REFUEL Act of 2025 (S. 2082), which would smooth the regulatory pathway for recycling used nuclear fuel.
President Donald nominated Nieh on July 30 to serve as NRC commissioner for the remainder of a term set to expire June 30, 2029, which was held by former NRC commissioner Chris Hanson, who Trump fired in June.

We discuss the technology developed at the Lebedev Physical Institute for the manufacture of hollow microspheres polyethylene terephthalate (PETP). The microspheres are produced by means of foaming solid PETP granules containing CO2 blowing agent in a vertical free-fall furnace. The diameter of obtained microspheres ranges from 50 to 800 µm, with aspect ratio typically from 10 to 50. Reasonably high maximum rupture strengths and relatively low permeabilities have been measured. These properties allow PETP microspheres to be used for long-duration storage of gases and in the technology of cryogenic targets for the ICF program.
