What Crane Nuclear does

Crane Nuclear is an operating division of Crane Co. (NYSE: CR) that designs, manufactures, and services valves, replacement parts, and diagnostic instrumentation for the global commercial nuclear power industry. Founded in 1956 and headquartered in Kennesaw, Georgia, the company serves BWR, PWR, AP1000, and Small Modular Reactor (SMR) operators across North America and select international markets. Its product portfolio spans a full line of safety-related valves (gate, globe, ball, check, butterfly, plug) marketed under multiple legacy OEM brands including Crane, Aloyco, Chapman, Pacific Valves, Stockham, XOMOX, Duo-Chek, Noz-Chek, Flowseal, and Flomatics, supported by a proprietary library of over 1,000,000 historical engineering drawings that enables exact-fit OEM replacement parts.

The company's diagnostic technology platform centers on the VOTES Infinity portable multi-platform diagnostic system for Motor-Operated Valves (MOVs), Air-Operated Valves (AOVs), and Check Valves, complemented by the VWave online monitoring system that delivers continuous at-the-valve data acquisition with cybersecurity hardening for nuclear environments. Supporting offerings include an extensive sensor and peripheral product line (force sensors, motor current sensors, pressure transducers, position encoders, optical DMT, digital torque switch transducers), the VOTES Infinity Calibration System (VICS), and a complete service stack covering outage services, diagnostic testing, engineering analysis, equipment calibration and repair, equipment rental, and a dedicated customer training program delivered through the Crane Nuclear Valve Institute (CNVI) in Kennesaw.

Revenue is generated through a mix of one-time product and replacement-parts sales, professional services tied to refueling outages (diagnostics, maintenance, repair, engineering), usage-based diagnostic equipment rental, and hardware sales of sensors and peripherals. The company operates an enterprise field-sales model with no public pricing, selling direct to nuclear utilities through quote-based engagements and deploying certified technicians, engineers, and project managers on-site for outage support. A 24-hour emergent parts hotline, mobile machining and actuator refurbishment trailers, and a stated 95%+ on-time delivery rate on replacement parts underscore a service model structured around outage-critical responsiveness. Quality programs are maintained to ASME N and NPT (over 35 years), 10 CFR 50 Appendix B, 10 CFR Part 21, ASME NQA-1-2015, and ASME NCA 3300/4250 standards, with routine audits by NUPIC, ASME, and other independent bodies.
