Holtec

SMR-300 major structures, systems and components are manufactured by Holtec's own US production fleet — a vertically integrated supply chain rather than an outsourced one. Current strategy supports a baseline of two SMR-300 units a year; further expansion is envisaged through the planned Holtec Heavy Industries facility. CAPACITY IS NOT DEMONSTRATED: this is what Holtec says its current strategy supports, not output it has achieved — no SMR-300 has been built, the Palisades construction permit having only been docketed in Feb 2026. The campus itself is long operating, for casks and other nuclear equipment.
