Diamond and Diamond-Like Materials as Hydrogen Isotope Barriers [PDF]

, 1999
This is the final report of a two-year, Laboratory Directed Research and Development (LDRD) project at Los Alamos National Laboratory (LANL). The purpose of this project was to develop diamond and diamond-like thin-films as hydrogen isotope permeation ...

Tritium Control and Mitigation in Fluoride-Salt-Cooled High-Temperature Reactors [PDF]

, 2019
Fluoride-salt-cooled high-temperature reactors (FHRs) receive wide attention because of their advantageous passive safety features and potential high thermal efficiency in power generation when compared with current commercial nuclear reactors.

Aluminum-Based Barrier Development for Nuclear Fusion Applications

, 2011
In the helium-cooled lead-lithium (HCLL) design concept for blanket structures of a future fusion power plant, the eutectic Pb-15.7Li alloy is used as a liquid tritium breeder and is in direct contact with the structural material, e.g., ferritic ...

Flibe/Be/He/FS concept (R = 1)

, 1984
The blanket concept is described. Beryllium, in the form of pebbles nominally 1 cm diameter in a 20 cm thick bed, is employed to multiply neutrons. The multiplier zone is followed by a zone of silicon carbide (SiC) which slows neutrons.

Adsorption, Absorption, Diffusion, and Permeation of Hydrogen and Its Isotopes in bcc Bulk Fe and Fe(100) Surface: Plane Wave-Based Density Functional Theoretical Investigations

, 2019
The fundamental understanding of adsorption, absorption, diffusion, and permeation of hydrogen and its isotopes is of paramount importance in controlling the hydrogen-induced embrittlement and also very helpful in the selection of barrier materials ...

Tritium retention in the ITER/DEMO actively cooled tungsten monoblock in the presence of neutron-induced defects

International audienceTritium retention in ITER like divertor monoblock is simulated with FESTIM adding trapping induced by neutron damage in the tungsten armor. The simulated scenario is a 10 MWm−2 heat flux representing an exposure near the strike line

Terpene-enhanced transdermal permeation of water and ethanol in human epidermis.

, 1997
The study was performed to investigate the effect of penetration enhancers on the stratum corneum barrier. Epidermal membranes were prepared from freeze-stored (-70 degrees C) Caucasian breast skin and mounted in a flow-through diffusion cell.
