Measurements of Gaseous Diffusion Coefficients
Accurate knowledge of molecular diffusion coeffi· cients and their temperature dependence is important in obtaining fundamental information on forces be· tween unlike molecules. Until recently most diffusion measurements were conducted over short temperature intervals because the conventional methods such as the Loschmidt or the Stefan, require the thermostating of large, static systems. Walker...

متن کاملNuclear Archaeology for Gaseous Diffusion Enrichment Plants
The field of nuclear archaeology aims to develop the methods and tools to verify past production of fissile materials for military purposes, which may become necessary to support the verification of future arms control agreements that envision deeper cuts in the nuclear arsenals. Techniques have been successfully demonstrated for reconstructing historic plutonium production, especially in graph...
متن کاملTime-period mortality patterns in a Gaseous Diffusion Plant workforce.
BACKGROUND We sub-divided a cohort of 6820 workers at the Paducah (KY) Gaseous Diffusion Plant (PGDP) which was traced from 1953 to 2003. The subdivisions were made to assess the mortality risks in a sub-group of workers employed solely during the plant's refit period, a time of suspected higher exposure to metal dusts (nickel, arsenic, chromium and uranium) and trichloroethylene. METHODS Thi...
متن کاملIntermediate pyrolysis of biomass energy pellets for producing sustainable liquid, gaseous and solid fuels.
This work describes the use of intermediate pyrolysis system to produce liquid, gaseous and solid fuels from pelletised wood and barley straw feedstock. Experiments were conducted in a pilot-scale system and all products were collected and analysed. The liquid products were separated into an aqueous phase and an organic phase (pyrolysis oil) under gravity. The oil yields were 34.1 wt.% and 12.0...
