"Matthias Huxley (real name: Dr. Presper, co-creator of Zax). Prepser is the "bad guy" of the piece (not really, but good enough), a cryogenically frozen scientist who went into hibernation a few days before the nuclear holocaust, woke up in the Boulder Dome, and emerged into the world to discover (to his surprise) how much "civilization" survived, before he wakes up the rest of the scientists frozen beneath the Boulder Dome. Prepser, as Scientific Advisor to the pre-war president, is the only person left alive who knows all the passwords and control schemes for the Zax computer and various other super-weapons across the world." by Chris Avellone. Zax is a Vault Tec creation. Boulder Dome was built by the government and Vault Tec for research, as stated in my OP, and as to conduct research on space travel and planetary settlements. To me this the Enclave.
