Abstract: It is presented, the method of stabilization and controlling of nuclear devices' parameters by means of usage of “absorbing shutter”. This method is based on usage of neutron's absorbing substance as “absorbing shutter” that split and shield active parts of nuclear device and may carry out the controlled changing own aggregate state for starting of initiation's process. When its aggregate state is changed, “absorbing shutter” can vary mechanical and physical parameters of a nuclear device's active main body. Prior to initiation, “absorbing shutter” holds the nuclear device into “below-critical configuration” and forms with parts of the nuclear device's active main body the monoblock that is not having significant hollow spaces. The hollow spaces' lacking gives to device mechanical properties of an incompressible solid body.

Abstract: A method and apparatus for cooling a planet uses an explosion to lift a dust cloud into the atmosphere. The dust cloud shields the surface of the planet from some sunlight. One aspect of the invention relates to detonating an explosive to generate a dust cloud and to create an updraft to lift the dust cloud into the atmosphere where it can be spread by winds over the area to be cooled. The dust in the atmosphere blocks sunlight from reaching the surface, allowing the planet to cool. Multiple explosions at multiple locations or at the same location may be use for greater cooling. Explosions may be caused by nuclear weapons or by the impact of an asteroid or comet.

Abstract: A nuclear power plant (18) and its heat exhanger (26) are enclosed in an envelope (22) which is suspended above a bored shaft (14) from a support stem (30). When appropriate, the stem (30) can be melted by a furnace (34) to drop the envelope (22) to the bottom of the shaft (14). Sand (42) can then be dropped onto the envelope (22) through a drainage pipe (46). While the nuclear power plant (18) is operating and suspended in the shaft, spent fuel rods (70) are dropped into a sand blasting machine's hopper (130), mixed with sand and dropped into a bag (134) containing a small explosive device. The bag (134) is then dropped to the bottom of the shaft (14) and the explosive detonated to scatter the contents of the bag (134). Optionally, more sand or earth is then added to reduce heat and radiation to acceptable levels.

Abstract: A weapon transport device transports along a path toward a target in hostile territory, (1) a target-intended weapon and (2) biological, chemical and/or radioactive agents for attacking the occupants of such territory should they execute countermeasures against the weapon transport device. Separation of the biological, chemical and/or radioactive agents is initiated or, where appropriate, inhibited, by signals from either the guidance system of the transport device or from on-board Global Positioning System (GPS) receivers when the transport device strays by more than a predetermined distance from the path, the sensor is blinded, or the transport device passes beyond a predetermined point while en route to the target.

Abstract: A system for obtaining spherically symmetrical implosion of sample materials by directing radiant ignition energy onto a target which includes a spherically symmetrical core of selected sample material concentrically surrounded by a shell of high explosive material. The resulting implosive compression produces hydrodynamically controlled physical and/or chemical and/or metallurgical transformations of state in the sample material.

Abstract: Large falling column-globs of molten sodium are dropped into positions around the center of a large explosion-containing chamber such that most of the effects of neutron-producing bursts, such as high energy photons, neutrons, and highly kinetic ions are attenuated and/or absorbed therein so as to prevent any damage to the chamber. This molten sodium absorbs most of the debris and produced energy of said bursts and is a working fluid by which said debris and such thermal energy is withdrawn from said chamber.

Abstract: A reactor system for producing useful thermal energy and valuable isotopes, such as plutonium-239, uranium-233, and/or tritium, in which a pair of sub-critical masses of fissile and fertile actinide slugs are propelled into an ellipsoidal pressure vessel. The propelled slugs intercept near the center of the chamber where the concurring slugs become a more than prompt configuration thereby producing a fission explosion. Re-useable accelerating mechanisms are provided external of the vessel for propelling the slugs at predetermined time intervals into the vessel. A working fluid of lean molten metal slurry is injected into the chamber prior to each explosion for the attenuation of the explosion's effects, for the protection of the chamber's walls, and for the absorbtion of thermal energy and debris from the explosion. The working fluid is injected into the chamber in a pattern so as not to interfere with the flight paths of the slugs and to maximize the concentration of working fluid near the chamber's center.

Abstract: A large free-falling mass with a hollow vertical hole therethrough is intercepted by a smaller sub-critical high velocity downward traveling mass and with a smaller sub-critical high velocity upward traveling mass. A resulting explosion is contained within a large chamber which contains much molten sodium spray which attenuates the effects of the explosion and absorbs the explosion's energy and debris. The heated molten sodium with debris provides useful thermal energy to a heat exchanger means and materials for new masses and for new assemblies that are manufactured from precipitate therefrom. The reactor system is a net consumer of plutonium and converts spent enriched uranium LWR fuels into enriched (mostly of U.sup.233) uranium by the neutron irradiation of thorium.
