Why This Nuclear Component Is Still Made by Hand

This nuclear component is still made by hand, and the reasons have nothing to do with nostalgia or tradition. At the center of modern nuclear power lies the reactor pressure vessel, a structure so large, so precise, and so unforgiving that human judgment remains irreplaceable. This video explores how a single factory in northern Japan came to dominate the global production of reactor pressure vessels by forging them from massive, single-piece steel ingots without welds. Viewers will gain a clear understanding of what a reactor pressure vessel actually does, why it must last for decades without replacement, and how neutron radiation, pressure, and heat impose demands no margin of error can tolerate. The story traces the full manufacturing process, from melting and refining steel over weeks, to months of repeated heating and open-die forging under presses applying forces measured in hundreds of meganewtons. Along the way, it explains why automation fails at this scale, how experienced forgers read temperature and material behavior by sight alone, and why every ingot behaves differently despite identical specifications. The video also places this manufacturing feat in historical and global context, connecting wartime forging, postwar nuclear expansion, Fukushima’s unintended stress test, and the renewed demand driven by decarbonization and small modular reactors. What emerges is a portrait of industrial craftsmanship that persists not in spite of modern technology, but because no technology has yet replaced it. Project Mystery explores the hidden systems, engineering decisions, and industrial processes that quietly shape the modern world. © Project Mystery 2026
