About this opportunity
The Department of Energy is seeking to procure vacuum seals and spring energized seals for the ITER vacuum system, with a specific focus on non-standard vacuum flanges for interface boundaries. The procurement will include Safety Important Components (SIC) that require ITER-style flanges with two seals and a sampling/monitoring port, as well as standard mating profile flanges for Non-SIC systems. The scope of work encompasses manufacturing, documentation preparation, packaging, and delivery to the ITER site near Cadarache, France. Contractors must be capable of producing commercially available seals that comply with ASME B31.3 construction codes, specifically using schedule 40S pipe and single machined piece flanges with integrated weld stubs. While specific evaluation criteria are not detailed in the pre-solicitation notice, potential bidders will likely be assessed on their technical capabilities, manufacturing expertise, and ability to meet precise engineering specifications.
The pre-solicitation notice indicates no specific set-aside designation for this contract opportunity, suggesting it is open to a broad range of qualified manufacturers. The contract is categorized under NAICS code 332999 for Miscellaneous Fabricated Metal Product Manufacturing and PSC code 5330 for Packing and Gasket Materials. The procurement was posted on February 28, 2025, with responses due by March 10, 2025, providing potential contractors approximately ten days to prepare their submissions. While exact award values are not specified, the technical complexity and specialized nature of the vacuum seals suggest a potentially significant contract value. The place of performance will be at the seller's facility, with final delivery required to the ITER site in France, indicating potential international shipping and logistics considerations for the selected contractor.

Vacuum Seals/Spring Energized Seals
The ITER vacuum system requires non-standard vacuum flanges for interface boundaries. For Safety Important Components (SIC), ITER style flanges are required. These flanges contain two seals and a sampling/monitoring port between the seals to allow for active monitoring of the seal interspace. For Non-SIC systems, standard mating profile ISO and Con-Flat (CF) type flanges are used, however, as the code of construction for the ITER machine is ASME B31.3 and requires at a minimum schedule 40S pipe, the standard tube-based fittings/weld stubs cannot be used. Instead, a single machined piece, flange face and weld stub, is required, along with these commercially available spring energized metallic seals. The scope consists of the manufacture, preparation of required documentation packages, packaging, and preparation for delivery to the ITER site near Cadarache, France. The seals covered under this SOW are expected to be a commercially available solution.(see Part #s above). Place of performance would be seller's facility.
