Comments on the Hydrogen Solubility Data for Liquid Lead, Lithium, and Lithium-Lead Alloys and Review of a Tritium-Solubility Model for Lithium-Lead Alloys

摘要

The projected use of a lithium-lead alloys as the tritium breeding blanket and heat transfer agent in fusion reactors requires data on the solubility of hydrogen isotopes in the alloys at the temperatures of interest. In the absence of available experimental data in the desired temperature range, estimates were made on the hydrogen isotope solubility in the lithium-lead alloys. In NUWMAK, solubility estimates were based on activity studies of lithium in lithium-lead while in WITAMIR the solubility was extrapolated from deuterium measurements in the alloy at higher temperatures. In this note we summarize the existing data and review our methods of estimating the tritium solubility in the desired temperature range. (ERA citation 06:035186)
