In building Teyla’s catio I might have to take a look into this door and its hinges!
The Door of Lawrence Livermore National Laboratory In California, USA.
The concrete-filled door measured 8 feet (2.4 meters) thick, almost 12 feet (3.7 meters) wide, and weighed 97,000 pounds (44 metric tons). It was fitted with a specially engineered hinge and bearing system that allowed a single person to open and close it despite its enormous weight.
This massive door served as radiation shielding for the Rotating Target Neutron Source-II (RTNS-II), which produced the most intense continuous stream of fusion neutrons ever generated. Scientists from around the world used RTNS-II to examine how different metals and materials would hold up under the extreme conditions expected inside future fusion power plants, providing vital knowledge for developing fusion as a clean energy source in the decades to come.
