Advanced nuclear workshop brings together Japanese and American experts
Tohoku University in Sendai, Japan, was the site of an advanced nuclear reactor workshop in late May that was hosted by the Fastest Path to Zero Initiative of the University of Michigan and Tohoku’s Center for Fundamental Research on Nuclear Decommissioning. The event was co-organized by the U.S. Consulate in Sapporo, Japan, and the Atlantic Council, which is associated with the North Atlantic Treaty Organization. The workshop, “The Potential Contribution of Advanced Nuclear Energy Technologies to the Decarbonization and Economic Development of Japan and the U.S.,” featured numerous American and Japanese academic authorities, government policymakers, executives of utilities and advanced reactor developers, and leaders of nongovernmental organizations. Also participating were students from both the University of Michigan and Tohoku University.

Tritium clean-up systems typically deploy gas processing technologies between stages of palladium-silver (Pd/Ag) diffusers/permeators. The number of diffusers positioned before and after a gas clean-up process to obtain optimal system performance will vary with feed gas inert composition. A simple method to analyze optimal diffuser configuration is presented. The method assumes equilibrium across the Pd/Ag tubes and system flows are limited by diffuser vacuum pump speeds preceding or following the clean-up process. A plot of system feed as a function of inert feed gas composition for various diffuser configuration allows selection of a diffuser configuration for maximum throughput based on feed gas composition.
