Not all nuclear reactors are built alike. Power plant designs can vary in their fuels, coolants and configurations, a fact beautifully illustrated by a series of reactor wall charts originally published in issues of Nuclear Engineering International during the 1970s and 1980s.
Since then, the charts have been lovingly collected by Ronald Knief, a nuclear engineer at Sandia National Laboratory. Recently, he completed his collection with help from the Idaho National Laboratory library and began to digitize the drawings. The first eight out of more than 100 have now been permanently archived online by the University of New Mexico libraries.
