How A Nuclear Reactor Vessel Is Made: The $80 Billion Seamless Steel That Forbids All Welds.

Описание: Imagine a single steel vessel, forged from a 600-ton ingot, guarding a core operating at 3,600°F—hot enough to instantly vaporize water. This is the ultimate containment: the nuclear reactor pressure vessel. We dive inside Japan Steel Works, the only facility in the world capable of forging these seamless, monolithic objects.

Witness the 12-story, 14,000-ton press—a force equivalent to stacking 70 Statues of Liberty—shaping the glowing steel. Discover the classified metallurgy required to survive 50 years of neutron bombardment, the surgical precision of de-sulfurization, and the absolute engineering paranoia that forbids a single weld. We also uncover the dramatic history of the Windscale Fire, the failure that proved why only seamless forging can prevent catastrophic rupture.
