Nuclear Material Requirements
Nuclear reactor components must perform reliably for 40 to 60 year plant lifetimes under the combined challenges of elevated temperatures, neutron irradiation (which degrades material properties over time), primary coolant chemistry (high-purity water with dissolved hydrogen or lithium hydroxide), and seismic loading requirements. The material selection spans multiple alloy families: Inconel 718 for high-strength fasteners and springs, Inconel 690 for steam generator tubing, Inconel 600/601 for structural internals, stainless steels (304, 316, CF8M) for piping and pump casings, and titanium for condenser tubes in seawater-cooled plants.
Components We Manufacture
CastAlloy produces nuclear components including reactor vessel closure studs and nuts in Inconel 718, control rod drive mechanism housings and components, steam generator tube support plates, reactor coolant pump internals, pressurizer heater sleeves and nozzle safe ends, and fuel handling equipment components. Our quality system supports nuclear-grade requirements with enhanced material traceability, extended documentation retention, and compliance with ASME Boiler and Pressure Vessel Code Section III requirements.
The SMR Opportunity
The emerging small modular reactor market creates new demand for high-performance alloy components. SMR designs often operate at higher temperatures than conventional light water reactors, expanding the need for superalloy components in heat exchangers, reactor vessel internals, and safety system hardware. CastAlloy's established superalloy manufacturing capabilities position us to serve this growing market. Contact us for nuclear component quotations.
