I have always loved tungsten as the gilded gold of reactor design. And now a reason has emerged to justify this appreciation of this wondrous metal that has come from hot fusion first wall design. Tungsten seems to protect itself from bursts of extreme heat by emitting a shield of cold hydrogen emanating from its surface. Tungsten is the preferred first wall material that protects the structure of a hot fusion reactor from the intense heat of a fusion reaction. It is performing better than expected because it sheds heat like a duck sheds water from its back. The next generation of LENR reactor would be well served to include loads of tungsten in their designs to push their operational temperatures as high as practicable.
