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.

The platinum on charcoal and polytetrafluorethylene (Pt/C/PTFE) is one of the most active and stable catalyst used for tritium removal from nuclear liquid effluents by isotopic exchange between hydrogen and water. This type of catalyst can be used alone or mixed with hydrophilic packing in so-called “mixed catalytic packing”. The mixed catalytic packing COMPACK CP-001 type has been selected and proposed by ICSI Rm-Valcea, to equip the liquid phase catalytic exchange (LPCE) columns from the future Industrial Tritium Removal from Cernavoda NPP (CTRF). The paper presents significant aspects concerning the manufacture of reproducible and homogenous batches of catalyst. Each preparation (follow: impregnation, drying, mixing, shaping and sintering) is presented and discussed. The main characteristics of Pt/C/PTFE catalyst (surface area; pores volume, metallic area, platinum particle size and SEM images are determined) in order to check the reproducibility and the homogeneity of catalyst batches manufactured by different workers. An automatic system for increasing of the productivity of manufacture has been manufactured and tested. The results of measurements on different batches handmade or automatic manufactured, showed close characteristics. This confirms the reproducibility of catalyst manufacture.
