Radiation Shielded Underground Vault Building built in 1971 by AT&T as a critical communication center to the missile defense system for a reported 9 million dollars. Building was designed to survive a direct hit from a 25 megaton blast from an atomic weapon and preserve sensitive electronic equipment inside. The building is a 112x149x15.5 foot below grade vault with the above grade serving as air loading dock, egress, air intake and exhaust. The building envelope features a minimum of 18" concrete or 2" steel plate doors. Blast valves and electromagnetic wave guides and wall placement geometry prevent radiation from entering the structure, ( in or out of) in addition the interior of the building is clad with a reflective sheilding. The building was designed to be sustained by three modes of electricity, commercial, battery, and self generated power. The transformers and switch gear are all located within the main vault adjacent to an engine room which was designed to hold up to 5 generators, two 25,000 gallon fuel tanks were installed to run the the alternators for an extended time, The engine/alternator room and the condenser room are situated near the exhaust air plenum to eject hot air. Other interior rooms include two mechanical rooms, the condenser room, a locker room and decontamination shower, storage and restrooms. The main room in the vault is roughly 110x90 and is called the telco equipment room. The air supply of the building draws air through lovered blast valves through an air filter bank. The filtered air passes through a fresh air intake shaft into the condenser room and is distributed to the engine room or through the ducting to the telco equipment room. The Army Corps of Engineers supervised the installation of a deep well for water reported to be nearly 860 feet deep. also there are two water holding tanks,10,000 gallons domestic water and 1800 gallon drinking water tanks. The property is situauated on nearly 14 acres close the 38th paralell in the center of the United States For further information call - Ask for Kenealy |
