General Nuclear Corp

General Nuclear Corp, a Subchapter S Corporation based in Ruffs Dale, Pennsylvania, manufactures precision-engineered metal components, valves, and fasteners for naval defense and space applications as a prime contractor under total small business set-asides to Naval Supply Systems Command and Naval Sea Systems Command. The company competes predominantly in total small business set-aside procurements, with 100% of its recent prime awards carrying small business designations.

General Nuclear Corp's federal footprint centers on naval-grade valve and fastener production. The company holds a $30 million single-award Blanket Purchase Agreement with Naval Supply Systems Command (awarded April 2026, running through April 2031) for whole body valves and valve piece parts, and a multiple-award Basic Ordering Agreement with Naval Sea Systems Command (through June 2029) for Level I nuclear-grade fasteners including cap screws, studs, nuts, and hardware fabricated from nickel-copper-aluminum, alloy steel, and Grade B7 steel. Representative recent work includes a $130.1 million firm fixed-price order from NAVSUP in January 2025 for nine diaphragm valves; a $875.8 thousand definitive contract from NAVSUP in August 2025 for seven STEM fluid valve assemblies; a $167.6 million purchase order from NAVSUP in February 2024 for diaphragm valves; a $145.9 million purchase order from NAVSUP in February 2024 for lower seal weld rings; a $83.1 thousand purchase order from NAVSUP in January 2027 for cap, vent, and valve assemblies; and a $72.4 thousand purchase order from NAVSUP in September 2025 for cap vent assemblies for nuclear reactor applications. Work is performed at the company's facility in Hunker, Pennsylvania.

Customer concentration is extreme and narrow. Naval Supply Systems Command accounts for 1,775 awards carrying a combined potential value of $110.8 million (81% of the portfolio's total), with a second tier of Naval Sea Systems Command (25 awards, $471 thousand) and a single $25 million award from the Department of Energy National Nuclear Security Administration. The remaining 155 Department of the Navy awards and 1 Office of Personnel Management award total $21 thousand. Nearly all volume flows through NAVSUP's indefinite delivery mechanisms: Indefinite Delivery Contract N0010404G7007 anchors 279 task orders ($2.2 million combined potential), Indefinite Delivery Contract N0010409G7002 carries 138 task orders ($2.9 million), and Blanket Purchase Agreement N0010416A7008 holds 29 task orders ($741 thousand).

Award activity has contracted year over year. The company received 100 awards in 2022, 67 in 2023, 77 in 2024, 68 in 2025, and 32 through mid-2026. The combined potential value across all 2,020 prime awards is $136.3 million, with $72.1 million currently obligated (53%). Fifty-seven awards carrying a combined potential value of $2.3 million reach ultimate completion inside the next twenty-four months and therefore face recompete.

The company's capability footprint spans industrial valve manufacturing (409 awards), other metal valve and pipe fitting manufacturing (383 awards), bolt/nut/screw/rivet/washer manufacturing (312 awards), and gasket/packing/sealing device manufacturing (249 awards). PSC concentration reflects the same profile: Valves, Nonpowered (538 awards); Nuclear Reactors (262 awards); Hose, Pipe, Tube, Lubrication, and Railing Fittings (233 awards); Packing and Gasket Materials (175 awards); Nuts and Washers (159 awards). The vendor operates as prime on nearly every award; only 2 sub-awards appear in the source, both recent (January 2024 to Fluor Marine Propulsion for cylindrical bar stock on the Naval Nuclear Laboratory program, and May 2025 to Curtiss-Wright Electro-Mechanical Corporation for cylinder head bottom machining).

General Nuclear Corp's federal position depends entirely on recurring Naval Supply Systems Command valve and fastener orders flowing through its BPA and BOA vehicles. The extreme customer concentration, narrow geographic footprint (single Pennsylvania manufacturing facility), and year-over-year award decline signal potential recompete and pipeline pressure, despite the scale of the current $30 million BPA vehicle and established nuclear-grade manufacturing credentials that position the company as difficult to displace on source-controlled, design-unique components for naval nuclear propulsion.
