Holtec International is a privately held American supplier of equipment and systems for the nuclear, solar, geothermal, and fossil power-generation industries. The company is best known for its spent-fuel storage and transport casks (HI-STAR, HI-STORM, HI-STORE CISF), decommissioning services through Holtec Decommissioning International (HDI), and its in-development SMR-300 small modular reactor — a roughly 320 MWe two-loop pressurized water reactor with an 80-year design life. Holtec is currently pursuing the first-ever restart of a permanently shut-down U.S. commercial nuclear power plant at Palisades in Michigan, which is also designated as the first deployment site for the SMR-300. The company runs manufacturing facilities in Camden, NJ, Pittsburgh, PA, and Orrville, OH, and partners with Hyundai Engineering & Construction (HDEC) on SMR-300 detailed design and full-scope plant construction.
