Production Of Tritium By Contained Nuclear Explosions In Salt

The results of all exchange experiments suggest that tritium produced by a contained nuclear explosion wiil be mixed with environmental water. Tritium exchange in the reaction HTO + H/sub 2/ in equilibrium HT + H/sub 2/O was catalyzed at 600 deg C by a number of oxygenated salts that occur in salt formations. Calcium sulfate was the best catalyst, with values as high as 49 and 77% with pure CaSO/sub 4/ and Drierite, respectively. in deep bed tests. Even under diffusion-controlled conditions, where reactant gases were passed over fine powders of CaSO/sub 4/, exchanges were as high as 26% for residence times of 50 sec. Sodium chloride had no effect. At high temperatures in a plasma jet, with D/sub 2/ as a stand-in for T/sub 2/, exchange was very rapid. For 90 msec residence time and a D/sub 2//H/sub 2/O feed ratio of 1.3, 53% of the water hydrogen exchanged with deuterium. (auth).

Molten Salt Reactors and Thorium Energy, Second Edition is a fully updated comprehensive reference on the latest advances in MSR research and technology. Building on the successful first edition, Tom Dolan and the team of experts have fully updated the content to reflect the impressive advances from the last 5 years, ensuring this book continues to be the go-to reference on the topic. This new edition covers progress made in MSR design, details innovative experiments, and includes molten salt data, corrosion studies and deployment plans. The successful case studies section of the first edition have been removed, expanded, and fully updated, and are now published in a companion title called Global Case Studies on Molten Salt Reactors. Readers will gain a deep understanding of the advantages and challenges of MSR development and thorium fuel use, as well as step-by-step guidance on the latest in MSR reactor design. Each chapter provides a clear introduction, covers technical issues and includes examples and conclusions, while promoting the sustainability benefits throughout. A fully updated comprehensive handbook on Molten Salt Reactors and Thorium Energy, written by a team of global experts Covers MSR applications, technical issues, reactor types and reactor designs Includes 3 brand new chapters which reflect the latest advances in research and technology since the first edition published Presents case studies on molten salt reactors which aid in the transition to net zero by providing abundant clean, safe energy to complement wind and solar powe
