The following was written by Richard Sauder, PhD, adapted from his book Underground Bases and Tunnels:

The nuclear subterrene (rhymes with 'submarine') was designed at the Los Alamos National Laboratory, in New Mexico. A number of patents were filed by scientists at Los Alamos, a few federal technical documents were written - and then the whole thing just sort of faded away.
Or did it?
Nuclear subterrenes work by melting their way through the rock and soil, actually vitrifying it as they go, and leaving a neat, solidly glass-lined tunnel behind them.
The heat is supplied by a compact nuclear reactor that circulates liquid lithium from the reactor core to the tunnel face, where it melts the rock. In the process of melting the rock the lithium loses some of its heat. It is then circulated back along the exterior of the tunneling machine to help cool the vitrified rock as the tunneling machine forces its way forward. The cooled lithium then circulates back to the reactor where the whole cycle starts over. In this way the nuclear subterrene slices through the rock like a nuclear powered, 2,000 degree Fahrenheit (1,100 Celsius) earthworm, boring its way deep underground.
The United States Atomic Energy Commission and the United States Energy Research and Development Administration took out Patents in the 1970s for nuclear subterrenes. The first patent, in 1972 went to the U.S. Atomic Energy Commission.
The nuclear subterrene has an advantage over mechanical TBMs in that it produces no muck that must be disposed of by conveyors, trains, trucks, etc. This greatly simplifies tunneling. If nuclear subterrenes actually exist (and I do not know if they do) their presence, and the tunnels they make, could be very hard to detect, for the simple reason that there would not be the tell-tale muck piles or tailings dumps that are associated with the conventional tunneling activities.
The 1972 patent makes this clear. It states:
"... (D)ebris may be disposed of as melted rock both as a lining for the hole and as a dispersal in cracks produced in the surrounding rock. The rock-melting drill is of a shape and is propelled under sufficient pressure to produce and extend cracks in solid rock radially around the bore by means of hydrostatic pressure developed in the molten rock ahead of the advancing rock drill penetrator. All melt not used in glass-lining the bore is forced into the cracks where it freezes and remains ...
"... Such a (vitreous) lining eliminates, in most cases, the expensive and cumbersome problem of debris elimination and at the same time achieves the advantage of a casing type of bore hole liner."
(U.S. Patent No. 3,693,731 dated Sept. 26, 1972)
There you have it: a tunneling machine that creates no muck, and leaves a smooth, vitreous (glassy) tunnel lining behind.
Another patent three years later was for:
A tunneling machine for producing large tunnels in soft rock or wet, clayey, unconsolidated or bouldery earth by simultaneously detaching the tunnel core by thermal melting a boundary kerf into the tunnel face and forming a supporting excavation wall liner by deflecting the molten materials against the excavation walls to provide, when solidified, a continuous wall supporting liner, and detaching the tunnel face circumscribed by the kerf with powered mechanical earth detachment means and in which the heat required for melting the kerf and liner material is provided by a compact nuclear reactor.
This 1975 patent further specifies that the machine is intended to excavate tunnels up to 12 meters in diameter or more. This means tunnels of 40 ft. or more in diameter. The kerf is the outside boundary of the tunnel wall that a boring machine gouges out as it bores through the ground or rock. So, in ordinary English, this machine will melt a circular boundary into the tunnel face. The melted rock will be forced to the outside of the tunnel by the tunnel machine, where it will form a hard, glassy tunnel lining (see the appropriate detail in the patent itself, as shown in Illustration 41). At the same time, mechanical tunnel boring equipment will grind up the rock and soil detached by the melted kerf and pass it to the rear of the machine for disposal by conveyor, slurry pipeline, etc.
And yet a third patent was issued to the United States Energy Research and Development Administration just 21 days later, on 27 May 1975 for a machine remarkably similar to the machine patented on 6 May 1975. The abstract describes:
A tunneling machine for producing large tunnels in rock by progressive detachment of the tunnel core by thermal melting a boundary kerf into the tunnel face and simultaneously forming an initial tunnel wall support by deflecting the molten materials against the tunnel walls to provide, when solidified, a continuous liner; and fragmenting the tunnel core circumscribed by the kerf by thermal stress fracturing and in which the heat required for such operations is supplied by a compact nuclear reactor.
This machine would also be capable of making a glass-lined tunnel of 40 ft. in diameter or more.
