Specifications include, but are not limited to: Procurement, Contracts and Materials Management is seeking Responsive Responsible Proposers to submit Proposals for the fabrication of a molten sodium loop. Oregon State University is currently working with industry partners to support the development of next-generation sodium fast reactor designs. In order to accomplish this goal, design work is currently underway for a large-scale thermal-hydraulic test loop which will operate at prototypic conditions using liquid sodium as the primary working fluid. This loop is designed, but will require creation of pipe isometrics and construction to allow the loop to characterize scaled down, mock-up fuel bundles, reactor vessel internal components, and test various component seals. a. Equipment Fabrication: The equipment will need to be fabricated. All instrumentation and control components will be provided by OSU via their ASME NQA-1 quality assurance program. Contractor will furnish piping and equipment framing. b. All wetted materials furnished by the vendor shall be Grade 304 stainless steel. c. Framing shall be mild structural steel, primed and painted with epoxy paint unless otherwise called out on drawings. d. Framing shall be painted safety blue with safety yellow hand rails. e. The loop will require the construction of a finned, air-cooled, heat-exchanger (HX-171). The exchanger region is cooled through air ducting.
