PR: American Nuclear Society welcomes Senate confirmation of Ted Garrish as the DOE’s nuclear energy secretary
Washington, D.C. — The American Nuclear Society (ANS) applauds the U.S. Senate's confirmation of Theodore “Ted” Garrish as Assistant Secretary for Nuclear Energy at the U.S. Department of Energy (DOE).
“On behalf of over 11,000 professionals in the fields of nuclear science and technology, the American Nuclear Society congratulates Mr. Garrish on being confirmed by the Senate to once again lead the DOE Office of Nuclear Energy,” said ANS President H.M. "Hash" Hashemian.

Experimental values for the viscosity of the radioactive hydrogen isotope tritium (T2) are currently unavailable in literature. The value of this material property over a wide temperature range is of interest for applications in the fields of fusion and neutrino physics, as well as to test ab initio calculations. As a radioactive gas, tritium requires a careful experiment design to ensure safe and environmental contamination–free measurements. In this contribution, we present a spinning rotor gauge–based tritium-compatible design of a gas viscosity measurement apparatus, or ViMA, capable of covering the temperature range from 80 to 300 K.
