Study about sorption of protium and mixture protium–tritium on sponge titanium

Fusion Engineering and Design, 2013
Abstract The Nuclear Power Plant Cernavoda is equipped with a CANDU reactor and is one of the most powerful tritium sources from Europe. The reactor is moderated and cooled with heavy water that is continuous enriched with tritium. The presence of the tritium decreases the capacity of the heavy water to moderate the nuclear reactions. For this reason,

Applicability of a cryogenic distillation system for D-T isotope rebalancing and protium removal in a DEMO power plant

Fusion engineering and design, 2019
The tritium plant at the future European DEMOnstration (DEMO) fusion power plant will require isotope separation systems for protium removal and isotopic rebalancing of the torus exhaust stream. Protium removal and isotopic rebalancing can occur within a

Ti–Cr–X protium absorbing alloys with high protium content for fuel-cell

Journal of Alloys and Compounds, 2003
Abstract The effects of additional elements to the Ti–Cr alloys on their protium absorption–desorption properties were investigated. Although Ti–Cr alloys with a b.c.c. structure is expected to exhibit a high protium content, it is difficult to obtain single b.c.c. phase quenching from the high temperature.

Protium removal from deuterium-tritium mixture with displacement chromatography method: Experiments and simulations

International journal of hydrogen energy, 2019
The displacement chromatography technique with a tri-column system was used to reduce the protium (H) in the deuterium-tritium (D-T) mixture, and the separation performance was studied numerically by ANSYS FLUENT. The experimental results showed that the

Fusion-neutron production during protium beam injection into protium—deuterium plasmas

Nuclear Instruments and Methods, 1979
The small deuterium content of natural hydrogen (1.5 × 10 −4 ) is shown to be capable of influencing neutron diagnostic measurements of neutral—beam—injected magnetically confined fusion plasmas.
