The Idaho National Laboratory has been a center for nuclear power research since 1949. It is far out in the desert and security is very tight, but there is one place where they have a few items on display. These are the HTRE-2 and HTRE-3 nuclear reactors which were built and operated in the 1950’s as part of an effort to develop nuclear powered jet bombers.
Oh, good. Never thought I’d like industrial pictures so much, but I like what you do with them.
