General Nuclear Corp

General Nuclear Corp, a small business subchapter S corporation based in Ruffs Dale, Pennsylvania, manufactures precision-engineered metal components, valves, and fasteners for naval defense applications as a prime contractor competing predominantly under total small business set-asides. The vendor operates manufacturing facilities in Hunker and New Stanton, Pennsylvania, with a specialized focus on nuclear-grade fasteners, valve assemblies, stems, disks, seals, rings, retainers, flanges, bonnets, studs, nuts, plugs, and related hardware serving the Naval Supply Systems Command and Naval Sea Systems Command. General Nuclear Corp competes almost exclusively under total small business set-aside designations across a footprint of 2,046 prime federal awards carrying combined potential value of $137.2 million, with 53 percent obligated.

Customer concentration is extreme and specialized. Naval Supply Systems Command accounts for 1,798 awards (97% of award count) and $111.5 million in combined potential value (81% of total portfolio value). Naval Sea Systems Command holds 28 awards valued at $646 thousand, while the Department of Energy National Nuclear Security Administration funds two awards totaling $25 million. This concentration reflects General Nuclear Corp's role as a dedicated supplier to naval nuclear propulsion and fleet logistics programs. Activity trended downward over five years—100 awards in 2022 declining to 58 in 2026—signaling either inventory adequacy on Navy side, increased competition, or capacity constraints at the vendor. Sixty-four awards with combined potential value of $2.7 million reach ultimate completion within the next twenty-four months, presenting recompete exposure concentrated in valve and fastener categories.

General Nuclear Corp holds two parent vehicles anchoring its capacity to execute: a $30 million single-award Blanket Purchase Agreement with Naval Supply Systems Command effective through April 15, 2031, supporting recurring whole body valves and valve piece parts (FSC 4820), and a multiple-award Basic Ordering Agreement with Naval Sea Systems Command running through June 30, 2029, for nuclear-grade X2 and BOA fasteners. These vehicles enable the vendor to respond to firm-fixed-price call orders across the Navy's supply ecosystem. Representative prime work includes a $875.8 thousand definitive contract for STEM fluid valve components (August 2025), a $167.6 thousand purchase order for diaphragm valves (February 2024), a $145.9 thousand order for lower seal weld rings (February 2024), and recurring sub-$150 thousand purchase orders for cap assemblies, pipe tees, seal rings, and retainers across the Naval Supply Systems Command footprint.

The subcontractor footprint is minimal. General Nuclear Corp performed two sub-awards: cylinder head bottom machining for Curtiss-Wright Electro-Mechanical Corporation on a motor alternating current project (May 2025), and cylindrical bar stock work for Fluor Marine Propulsion LLC supporting the Naval Nuclear Laboratory (January 2024). These engagements position the vendor in the naval nuclear propulsion industrial base supply chain, though sub revenue represents negligible portfolio share. The vendor's primary revenue model is direct prime contracting to Naval Supply Systems Command under blanket purchase agreements and purchase orders, not subcontracting leverage.

Primary NAICS categories center on Industrial Valve Manufacturing (409 awards), Other Metal Valve and Pipe Fitting Manufacturing (391 awards), Bolt, Nut, Screw, Rivet, and Washer Manufacturing (315 awards), and Gasket, Packing, and Sealing Device Manufacturing (249 awards), with PSC concentration in Valves, Nonpowered (547 awards) and Nuclear Reactors (263 awards). The portfolio reflects deliberate specialization in components critical to naval propulsion and logistics—valve stems and disks, nuclear-grade fasteners, seal assemblies, and related precision hardware. No SBA certifications beyond small business status appear in the award record; the vendor competes as a total small business across 100 percent of documented federal contract volume. General Nuclear Corp has maintained continuous federal registration in SAM.gov since 2002, establishing two decades of demonstrated performance delivering specialized metal components to naval programs without diversification into civilian or non-defense markets.
