Abstract: Passive emergency cooling in response to a loss of coolant accident (LOCA) in a PWR, having an integral reactor pressure vessel incorporating the steam generators and housed in a small high pressure containment vessel, is provided by circulating cooling water through the steam generators and heat exchangers in an external tank to cool the reactor vessel at a rate sufficient to lower the pressure in the reactor vessel below that in containment the reverse mass flow out of the reactor vessel and keep the reactor core covered without the addition of makeup water. Suppression tanks inside the small high pressure containment structure limit peak blowdown pressure in containment and provide flood-up water and gravity fed makeup water to cool the core. Diverse cooling is provided by natural circulation of air, and if needed, water, over the spherical containment structure.

Abstract: A method and apparatus for driving nuclear reactions in a controlled manner within a shaped cavitation nuclear reactor or CNR is provided. The shape of the CNR is generally cylindrical, with the central region of the reactor having a substantially smaller diameter than either end portion. Due to this shape, the central reactor region undergoes enhanced cavitation with numerous reaction sites being in close proximity to the surface of the reactor's central region. As a result, the shaped reactor configuration is well suited for use as a photon/particle source. Attached to either end of the CNR is a driver assembly, the driver assemblies being used to couple acoustic energy into the reactor. The CNR may be contained within a high pressure enclosure fabricated from a material capable of withstanding the high reactor operating temperatures. Preferably the high pressure enclosure is encased in one or more layers of thermal insulation, followed by an outer enclosure. Coolant, fed through one or more nozzles, impinge upon the outer surface of the reactor thereby providing reactor cooling as well as a means of generating a high pressure fluid such as vapor or steam. The high pressure fluid is, in turn, coupled to an energy conversion system such as a steam turbine, heater radiator, steam piston motor, or other heat exchanger. The reactor system may include one or more static stress amplitude modulators which provide a means of simultaneously applying a static force with the dynamic forces applied by the drivers.

Abstract: A new and improved system for facilitating heat removal from a cavitation nuclear reactor. Cavitation nuclear reactors generally have a reaction chamber within which the cavitation nuclear reactions take place. Cavitation nuclear reactions are driven by acoustic energy. In order to generate the necessary acoustic energy, drivers are connected to the reaction chamber. This new and improved system utilizes two independant circuits to increase the efficiency of the cavitation nuclear reactors. One circuit serves to remove the energy from the interior of the reaction chamber at as high a temperature as possible. The other circuit acts to cool down the drivers so as to allow the drivers to operate within the optimal operating temperature range. Additional fins or extensions are added to protrude from the outer surface of the chamber, or alternatively, the outer surface of the chamber is corrugated to increase the amount of heat flow from the interior of the chamber.

Abstract: A method and apparatus for driving nuclear reactions in a controlled manner within a cavitation nuclear reactor or CNR is provided. In general, the CNR is comprised of a solid material and, more particularly, comprised of a fuel material interspersed within a host material. The CNR can utilize any of a variety of different shapes. Energy, typically in the form of acoustic energy, is driven into the CNR with one or more drivers in order to create a pressure intensity pattern within the reactor. As a result of the pressure intensity pattern, at numerous locations within the reactor the energy is large enough to form small cavities or bubbles. Due to the phenomena of cavitation, the applied energy causes the newly formed bubbles to oscillate, undergoing a period of expansion followed by a period of bubble collapse. The velocity of the spherically converging material associated with the cavitation cycle, often times reaching supersonic velocities, is sufficient to achieve a density and temperature in excess of that required to drive a variety of different nuclear reactions including fusion, fission, spallation, and neutron stripping. If desired, an external heat source can be used to heat the material comprising the CNR, thereby promoting the desired nuclear reactions. In a specific embodiment, the CNR is driven at a frequency that either substantially matches a resonant frequency of the CNR or substantially matches an integer multiple of a resonant frequency.

Abstract: A support grid for laterally maintaining the relative position of elongated fuel elements within a fuel assembly for use within a core of a nuclear reactor. The grid is formed in the shape of a lattice with the intersecting lattice members defining a plurality of cells, most of which respectively support the nuclear fuel elements. The reamining cells support nuclear control rod guide tubes and instrumentation thimbles. The cells supporting the nuclear fuel elements are provided with diagonally positioned springs on two, adjacent walls. The springs support the fuel elements against dimples which protrude from the opposite cell walls. The adjacent, diagonal springs in each fuel element cell are inclined in opposite directions. The walls of the cells supporting the control rod guide tubes are embossed along their height at the locations intermediate the intersection between adjoining walls with a concave notch having a curvature which conforms to the outside surface curvature of the control rod guide tubes. The grid is provided with mixing vanes which are positioned in a symmetrical, regional pattern, with the pattern varying between adjacent regions, and configured such that the hydraulic forces across the center of the grid are balanced. The grid is reinforced with welds at the mid point of the intersection of the lattice straps.
