Cooling System Check Valve Replacement

The Idaho National Laboratory (INL) is seeking an Expression of Interest (EOI) from qualified vendors capable of providing tilting-disc style, 20-inch, 300-lb check valves for use at the Advanced Test Reactor (ATR). The valves are critical safety-related components used on the discharge side of high-capacity pumps and support safe operation of ATR. The scope of work includes designing, manufacturing, testing, and delivering a quantity of four check valves, each with specific requirements such as material compatibility, performance capability, and testing and inspection. The selected vendors may be invited to participate in a Request for Proposal (RFP) process for award consideration. Some key points to consider are: • The valves must meet stringent design, operational, environmental, and safety requirements. • The vendors must be capable of designing, manufacturing, testing, and delivering the check valves. • The vendors must provide documentation, including dimensional outline and cross-section drawings, recommended spare parts list, and certificates of conformance. • The vendors must comply with INL data control requirements. • The vendors must provide a high-level cost estimation for delivery of four check valves.
