About this file
This PowerPoint appendix is part of a Request for Information (RFI) for the Liquid Argon (LAr) Supply for the Long-Baseline Neutrino Facility (LBNF/DUNE) project located in Lead, South Dakota. The document provides technical details about the liquid argon receiving and storage infrastructure, including a proposed facility layout with 4 x 50 m3 storage tanks capable of holding 280 tons of liquid argon (supporting approximately 3.5-4 days of supply at 70 tons per day), redundant 500 kW vaporizers, and an argon purity shed for quality control and sampling.
The appendix includes project timeline information, cryogenics process flow diagrams, site access details (highlighting the steepest incline at Mill St. Grade), surface facility layouts, and conceptual design drawings for argon receiving stations. The project is being managed by David Montanari from FDC Cryogenics and is associated with a Department of Energy Fermi National Accelerator Laboratory solicitation (LBNF-2025-LAR-RFI-JD), indicating this is a pre-solicitation market research document to understand potential liquid argon supply capabilities and infrastructure requirements.
