Tritium Laboratory Karlsruhe Tritium Infrastructure: Current Status and Upgrades for Future Operations

The Tritium Laboratory Karlsruhe (TLK) is a unique semitechnical facility dedicated to the development of tritium processing technologies encompassing analytical systems, processing methodologies, and experimental setups. Authorized to handle up to 40 g of tritium, TLK represents a central facility within the Helmholtz Association for tritium-related research and development. Since commencing operations in 1993, its proven confinement and processing philosophy has established an excellent safety record. This paper provides an overview of the current status of TLK’s tritium infrastructure, summarizing operational experience, organizational frameworks, and recent technical progress. Developments addressing solutions to operational challenges, new facility interfaces, and the commissioning of a dedicated tritium isotope recovery plant are presented. An outlook on the planned tritium waste disposal facility underlines TLK’s continuous commitment to innovation in tritium handling technologies.
