MARVEL PDSA approval could serve as blueprint
MARVEL, the Microreactor Applications Research Validation and Evaluation project at Idaho National Laboratory, has had its preliminary documented safety analysis approved by the Department of Energy, marking a milestone in its development and serving as a potential outline for other microreactors in development.

H2 permeation behavior in a new molten salt of Flibe mixed with 0.5 wt% Ti powder is experimentally and analytically investigated. Ti powder included in Flibe can suppress H2 permeation for 70 hours lower than the H2 detection limit after the start of experiment. H2 diffusion behavior in the Flibe+Ti system is analyzed using an unsteady-diffusion equation. The time delay of overall H2 diffusion in the Flibe+Ti system is over 200 times larger than that in Flibe. The effective diffusivity and solubility in the Flibe+Ti system are determined from fitting the analytical solution to experimental H2 permeation rates.
