About this opportunity
The Department of Energy, through Oak Ridge National Laboratory, is procuring water-cooled gate valves for the Material-Plasma Exposure eXperiment (MPEX), a superconducting magnet device designed to conduct accelerated lifetime tests of plasma-facing components under harsh fusion reactor conditions. The gate valves must provide leak-tight vacuum chamber barriers when plasma is not present, remove heat when plasma is active and the valve is open, and supply cooling water inlet and outlet ports. Contractors must have quality assurance programs compliant with ISO 9001 or NQA-1 standards and deliver comprehensive technical documentation including quality plans, design packages, thermomechanical analysis, maintenance procedures, and calibration records. The procurement will use a Lowest Price Technically Acceptable (LPTA) evaluation method under NAICS code 332911 for Industrial Valve Manufacturing. The solicitation was posted on August 26, 2025, with proposals due by September 15, 2025, at 5:00 PM EST, and offers must remain valid for 120 days.
This solicitation does not include any set-aside designation and is open to all qualified contractors. The procurement calls for two water-cooled gate valves constructed of Grade 316 Stainless Steel with DN275CF sealing features and stringent vacuum performance standards. Key deliverables include a Quality Plan within 2 weeks of subcontract award and a Design Package within 24 weeks, with the contract structured as a firm fixed price arrangement. The place of performance is Oak Ridge National Laboratory in Oak Ridge, Tennessee, with delivery specified as Delivered at Place (DAP) terms where the seller is responsible for packaging and shipping to ensure undamaged arrival. Payment terms are net 30 days with all payments made in U.S. dollars via electronic funds transfer, though no specific contract value or budget range is disclosed in the available documentation.
Notice text
Vacuum Gate Valves
The Material-Plasma Exposure eXperiment (MPEX), a superconducting magnet, steady-state device, is being built at Oak Ridge National Laboratory (ORNL), herein referred to as “the Company”, to address the harsh conditions inside a fusion reactor. This device, as designed, will have the unique feature of being able to conduct accelerated lifetime tests of plasma-facing components, including those that have experienced neutron damage.
The primary role of the water-cooled gate valve is to provide a leak tight vacuum chamber barrier when plasma is not present and the mating vacuum chambers are separated, remove heat that is gate valve when the plasma is present and the gate valve is open, and provide inlet and outlet ports for cooling water.
