ATR Loop Pressurizer Fabrication
Battelle Energy Alliance, LLC (BEA), the management and operating contractor for the U.S. Department of Energy-owned Idaho National Laboratory, seeks expressions of interest from qualified vendors to fabricate an ASME Section VIII, Division 2 pressure vessel for the ATR Loop Pressurizer (1A-NE Loop). The work includes fabricating, inspecting, and testing the vessel and associated components, supplying materials, preparing required documentation, and delivering the completed unit to Idaho Falls. This is an expression-of-interest stage to identify qualified vendors, and selected respondents may later be invited to a formal RFP process.
