The US nuclear industry is operating under a very different set of pressures than it was twenty years ago. Park Nuclear sees that shift firsthand through utilities trying to keep older infrastructure operating far longer than originally planned. Some plants are extending reactor lifespans while others are restarting retired facilities or preparing for new reactor programs. At the same time, many of the manufacturers and supplier networks tied to legacy nuclear infrastructure have either narrowed their nuclear focus or exited the market entirely. Inside plants, the challenges are immediate and operational. Replacement parts are becoming harder to secure while lead times continue to stretch. Engineers are working around systems installed decades ago, often with limited vendor support and incomplete historical documentation. Procurement teams are balancing outage schedules, regulatory expectations and supply-chain uncertainty at the same time, leaving very little room for delay when critical equipment fails. That environment is where Park Nuclear built its business. Founded in 1988, the company focuses on obsolete components, unsupported systems and nuclear sourcing problems that emerge after conventional procurement channels stop producing viable answers. Utilities often contact Park Nuclear when OEM support disappears, outage windows tighten or a failed component begins threatening operational continuity. In nuclear operations, however, finding a replacement part is only one part of the challenge. Qualification history, traceability, testing records and regulatory documentation matter just as much as the component itself. A technically compatible part without defensible documentation can still create engineering exposure, compliance complications and additional outage risk. From its 125,000-square-foot facility in Pasco, Washington, Park Nuclear maintains more than 350,000 parts connected to legacy nuclear infrastructure across North America, including original unused equipment no longer available through standard commercial channels. During outages, access to that inventory can determine whether utilities maintain schedules or absorb costly delays across plant operations.

Cold-chain operators are under increasing pressure to reduce fuel costs, meet emissions targets and maintain reliable refrigeration performance across demanding transport environments. Nivalis Energy Systems solves a challenge many fleet operators continue to face: adopting electrified refrigeration systems without sacrificing reliability, scalability or cost competitiveness. “We deliver an electric solution that provides an economic benefit to customers versus diesel and provides performance capabilities equivalent to or better than diesel systems,” says Sam Plunkett, chief executive officer. Nivalis developed its TRU-POWER® system specifically for battery-electric transport refrigeration applications. Rather than relying heavily on non-optimized off-the-shelf components, Nivalis engineered advanced battery and power electronics systems designed around the operational requirements of refrigerated fleet operators. The design strategy focused on reducing total cost of ownership while maintaining the usability, serviceability and reliability fleet operators expect from diesel-powered refrigeration units. Nivalis also structured the system around modular installation requirements, allowing trailers to be outfitted and returned to service within two days through its nationwide dealer and installer network. It believes minimizing installation downtime is essential for broader fleet adoption because operators remain highly sensitive to disruptions affecting route schedules and equipment availability..
