Battelle Energy Alliance (BEA) for Idaho National Laboratory is seeking expressions of interest from qualified firms to design, fabricate, test, inspect, and deliver a 200-cubic-foot ASME BPVC Section VIII Div. 1 “U”-stamped pressure vessel (V-738) for gaseous CO2 service at INL’s Central Facilities Area Carbon-based Fuels Capability (CFA-686). The horizontal vessel requires 304/304L stainless steel construction, 1,800 psig design pressure, -40°F to 500°F design temperature, saddle supports, seven nozzles, band heating elements, and Foamglas-equivalent insulation with aluminum sheathing, designed for outdoor high-desert static, seismic, and wind loads. The anticipated firm-fixed-price contract duration is 28 weeks after receipt of order, covering ASME Code design/analysis, fabrication drawings, WPS/PQR approval, shop fabrication, heating/insulation, shipping to INL, and final Code Data Report/deliverables. Interested firms must demonstrate current “U” stamp capability, stainless steel pressure-vessel welding/radiography experience, inspection/examination/testing plans, ASME Appendix 10 QC and Appendix 47 design compliance, and qualified project/QC management; only qualified responders may receive an RFP. Selection is anticipated in November 2026, and performance/installation will be at INL in a high-desert outdoor environment at 4,900 ft altitude with ambient temperatures from -40°F to 100°F.

Battelle Energy Alliance (BEA) is seeking Expressions of Interest from qualified firms for a design/build contract to design, fabricate, test, inspect, and deliver a horizontal 200-cubic-foot ASME BPVC Section VIII Division 1 “U”-stamped CO2 storage pressure vessel (V-738) for the CFA-686 Carbon-based Fuels Capability at Idaho National Laboratory (INL), Central Facilities Area. The vessel will operate outdoors in an INL high-desert environment and be built from 304/304L stainless steel with 1,800 psig design pressure, -40°F to 500°F design temperature, two saddle supports, seven nozzles, nine band heating elements, and Foamglas or equivalent insulation with aluminum sheathing. The anticipated project schedule after receipt of order includes ASME Code design/analysis at 3 weeks, shop fabrication drawings at 4 weeks, WPS/PQR approval at 3 weeks, complete shop fabrication at 25 weeks, heating element installation/insulation at 26 weeks, shipment to INL at 27 weeks, and final Code Data Report/as-built drawings/deliverables at 28 weeks. Interested firms should demonstrate ASME Section VIII Division 1 design/fabrication experience, a current “U” stamp, stainless steel pressure vessel welding and NDE/testing capabilities, compliance with Mandatory Appendix 10 and 47, and qualified project manager/QC manager availability. Responses will be used to identify qualified vendors; selected firms may receive an RFP under a firm-fixed-price award, with the selection decision anticipated in November 2026.
