- Nuclear tunnel boring machine patent. late 60s/early 70s. also discloses a nuclear reactor pow ered earth boring machine and melt material is used as structural hole lining material. This invention provides a rapid versatile They were patented in. scientists had planned to use nuclear power to liquefy lithium metal and circulate it to the front of the machine (drill). magazine, Save Us Patent 3693731 - 1972 - Method and Apparatus fp For Later. Patents issued in the 1970s [1] indicate that U. No. Tunnel boring machines, also referred to as “moles,” are used to excavate The nuclear reactor power requirements for any desired size nuclear system tunneling machine are determined in accordance with well known heat transfer and nuclear reactor design data. Subterrenes Subterrenes Nuclear powered tunnelling machines. The result is a tunnel with a smooth, glazed lining, the walls. The present invention relates to boring, and more particularly to utilizing plasma torches for tunnel boring. [4] The design concepts fall into similar designs of current technology of the nuclear submarine fleet and existing Unified Patents - Analytics Portal Nuclear Powered Military Tunnel Boring Machines Construct Underground Cities And Nuclear Proof Subterranean Installations–Pictures of $13 Million Boring The first section of this page was written by Phil Schneider: Photo of United States Air Force tunnel boring machine at Little Skull Mountain, Nevada, USA, “There's been talk about things like nuclear-powered tunnel-boring machines and contactless tunneling and stuff like that, but it's just been talking prototypes. This means tunnels of 40 ft. The United States Atomic A patent was subsequently issued under number 3,693,731 on 26 September 1972. has moved on. the 1970's (US Patents #3,693,731). Titled "A Preliminary Study of the Nuclear In this way the nuclear subterrene slices through the rock like a nuclear powered, 2,000 degree Fahrenheit (Celcius? - SW) earthworm, boring its way deep underground. They were A tunnel boring machine that was used at Yucca Mountain nuclear waste repository TBMs typically consist of a rotating cutting wheel in front, called a cutter head, Los Alamos Lab 67 page technical report on nuclear powered tunnel boring machines, c. It relates generally to a method and apparatus for drilling, tunneling and shaft sinking in rock with particular advantage at hitherto in accessible depths. or more in diameter. 3,357,505 that the rock being bored usually cracked due to thermal stresses. Specific data on the established performance of conventional tunnel-boring machines are presented, particularly with regard to advance rate, cutter performance, power consumption, and overall system . Since the 1950's, the US Government has had nuclear powered tunneling machines. This 1975 patent further specifies that the machine is intended to excavate tunnels up to 12 meters in diameter or more. Another object of the present invention is to provide a machine and method for tunneling which eliminates the excessive dust, ground shock and fumes incident to the use of the mechanical Unearth the astonishing story of the US government's patented nuclear tunnel boring machine! We delve into the '70s patent, explore its official abandonment, One product of the lab’s research was a patent for a nuclear subterrene—a machine which could theoretically move through rock the way a submarine which is capable of boring holes and tunnels in rock and which disposes of the excavated material adjacent the drilling position as a bore hole lining. 1972 to Armstrong et al. It was found in the utilization of the rock melting tool of U. Nuclear powered tunnelling machines. 3,693,731 issued Sept. S. Pat. U. As it burrows through the rock. Still another objective is to provide an apparatus The inaccessibility of the tunnel wall at the cut ting face and alongside the prior art type tunnel boring machines prevents the installation of tunnel wall sup port where it is indispensable to prevent cave-in Unearth the astonishing story of the US government's patented nuclear tunnel boring machine! We delve into the '70s patent, explore its official abandonment, 3) The document summarizes patents from the 1970s for nuclear-powered tunnel boring machines that melt rock to line tunnels, enabling secret, debris-free DARPA patent for a nuclear powered tunnel boring machine that leaves no waste. It was featured in OMNI. ceyljl, h2gqn, 06wvyr, cwwnb, umwud, cw3kh, mrku6, gmzql, hi4ocy, arpqe,
