Solicitation LBNF-335217-JD is issued by Fermi Research Alliance LLC (FRA) to seek proposals for the supply of safety valves on the inline side penetrations of Cryostats 1 and 2 within the Long-Baseline Neutrino Facility (LBNF). The supply scope encompasses the design and production of eight (8) valves, inclusive of testing and certification, as well as packing and shipping. Specific requirements are identified in the Statement of Work.
Project Background: LBNF (http://lbnf-dune.fnal.gov/) will provide the infrastructure necessary to support the massive neutrino detectors located deep underground at the Sanford Underground Research Facility (SURF) in Lead, South Dakota (SD). The Deep Underground Neutrino Experiment (DUNE) will employ four (4) such detectors, housed in cryostats requiring almost 70,000 tons of liquid argon (LAr), about 17,400 tons for each cryostat. DUNE (http://www.dunescience.org/) is expected to achieve transformative discoveries, making definitive determinations of neutrino properties, examining the dynamics of supernovae that produced the heavy elements necessary for life, and probing the possibility of proton decay.
