What The Park Company Llc does
The Park Company LLC, doing business as Park Nuclear, is a privately-held specialist supplier, service provider, and reverse-engineering firm for the commercial nuclear power industry, founded in 1989 and headquartered at a 125,000 sq ft facility in Pasco, Washington. The company's core asset is the largest nuclear power plant parts inventory in North America — more than 350,000 mechanical, electrical, and instrumentation-and-controls (I&C) components — focused on obsolete and hard-to-find parts for aging US reactors. Beyond the catalog, Park Nuclear operates an SPARES program (pre-tested parts aligned with INPO IER 21-4), a reverse-engineering and drop-in-replacement service that recreates components from OEMs that have been out of business for decades, an item-equivalency analysis service, repair and testing, and strategic sourcing from global supplier networks.
Through a March 2025 acquisition from MicroMod Automation, the company now owns the 53MC5000 multiloop process controller product line — including intellectual property, manufacturing rights, and support services — with installed bases in CANDU, PWR, and BWR facilities across the Americas, Europe, and Asia. A second 45,000 sq ft Engineering & Qualification Center in Oak Ridge, Tennessee, scheduled for Q4 2025 launch, will deliver NQA-1 compliant quality assurance, Commercial Grade Dedication, and Seismic and Material Testing under 10 CFR 50 Appendix B.
Park Nuclear makes money through a mix of one-time transactional parts sales (large catalogs of individual or bulk obsolete components), professional services (repair, testing, strategic sourcing, reverse engineering, item equivalency, inventory reduction), and hardware revenue from the 53MC5000 product line. Pricing is quote-based and not publicly disclosed, reflecting the highly variable nature of nuclear-grade part specifications and qualification requirements. Go-to-market is exclusively direct: a field-sales organization that conducts on-site visits to nuclear utility buyers (engineering, supply chain, maintenance, executive teams) across multiple states, supplemented by a heavy presence at industry events (RAPID, NUPIC, NBIC, NECX, USA Winter Conference, AUG/MUG, ETEBA BOTC, WM Symposia, MOV/AOV). Named enterprise customers span Xcel Energy, PG&E Diablo Canyon, Constellation Nuclear, American Electric Power, Vistra Energy, Exelon Generation, Entergy, and the broader US nuclear fleet. The company has received the Utilities Service Alliance Materials Supplier of the Year award for two consecutive years (2025 and 2026).
