  • Publication number: 20210313080
    Abstract: A fast neutron nuclear reactor contains a nuclear reactor core having an array of device locations. Some device locations in the nuclear reactor core contain fissile and fertile nuclear fuel assembly devices. One or more other device locations in the nuclear reactor core contain Doppler reactivity augmentation devices that amplify the negativity of the Doppler reactivity coefficient within the nuclear reactor core. In some implementations, a Doppler reactivity augmentation device can also reduce the coolant temperature coefficient within the nuclear reactor core. Accordingly, a Doppler reactivity augmentation device contributes to a more stable nuclear reactor core.

  • Publication number: 20210095645
    Abstract: An integrated energy system includes a nuclear thermal plant situated on a nuclear site. The nuclear thermal plant produces thermal energy that is transported to a thermal energy storage system located outside the nuclear site. The thermal storage system is thermally coupled to a power generation system which is also remote to the nuclear site. By this arrangement, the nuclear thermal plant is isolated and decoupled from the power generation system. The nuclear thermal plant may supply thermal energy upwards of 800° C. or more to be stored at the thermal energy storage system until needed such as for industrial heat, power generation, or other uses. The thermal storage system is source agnostic, and one or more additional thermal energy generators, such as additional nuclear reactors, solar thermal plants, or other thermal energy generators can be coupled to a common thermal storage system and power generation system.

  • Patent number: 10671168
    Abstract: Described embodiments include a system and a method. A system includes a first ultrasound transmitter acoustically coupled to a conducting layer of a display surface and configured to deliver a first ultrasound wave to a selected delineated area. The first ultrasonic wave has parameters sufficient to induce a non-linear vibrational response in the conducting layer. A second ultrasound transmitter is acoustically coupled to the conducting layer and configured to deliver a second ultrasound wave to the selected delineated area. The second ultrasonic wave has parameters sufficient to induce a non-linear vibrational response in the conducting layer. A controller selects a delineated area in response to an indication of a touch to the display surface, and initiates delivery of the first and second ultrasonic waves. A convergence of the first and second ultrasonic waves at the selected delineated area produces a stress pattern perceivable or discernible by the human appendage.

  • Patent number: 10655883
    Abstract: A system and associated methods of operation for regulating an environmental variable (such as ambient room temperature) within a target zone. The system includes an occupancy sensor configured to monitor the target zone and determine a number of inhabitants present within the zone. The occupancy sensor generates an occupancy signal communicating the number of detected inhabitants to an environmental control system. Upon receiving the occupancy signal, the environmental control system regulates an environmental variable within the zone based on the number of inhabitants present in the zone.

  • Publication number: 20200118698
    Abstract: A molten salt reactor includes a nuclear reactor core for sustaining a nuclear fission reaction fueled by a molten fuel salt. A molten fuel salt control system removes a volume of the molten fuel salt from the nuclear reactor core to maintain a reactivity parameter within a range of nominal reactivity. The molten fuel salt control system includes a molten fuel salt exchange system that fluidically couples to the nuclear reactor core and exchanges a volume of the molten fuel salt with a volume of a feed material containing a mixture of a selected fertile material and a carrier salt. The molten fuel salt control system can include a volumetric displacement control system having one or more volumetric displacement bodies insertable into the nuclear reactor core. Each volumetric displacement body can remove a volume of molten fuel salt from the nuclear reactor core, such as via a spill-over system.

  • Publication number: 20200105425
    Abstract: A nuclear reactor includes a passive reactivity control nuclear fuel device located in a nuclear reactor core. The passive reactivity control nuclear fuel device includes a multiple-walled fuel chamber having an outer wall chamber and an inner wall chamber contained within the outer wall chamber. The inner wall chamber is positioned within the outer wall chamber to hold nuclear fuel in a molten fuel state within a high neutron importance region. The inner wall chamber allows at least a portion of the nuclear fuel to move in a molten fuel state to a lower neutron importance region while the molten nuclear fuel remains within the inner wall chamber as the temperature of the nuclear fuel satisfies a negative reactivity feedback expansion temperature condition. A duct contains the multiple-walled fuel chamber and flows a heat conducting fluid through the duct and in thermal communication with the outer wall chamber.

  • Publication number: 20200027577
    Abstract: A fuel element has a ratio of area of fissionable nuclear fuel in a cross-section of the tubular fuel element perpendicular to the longitudinal axis to total area of the interior volume in the cross-section of the tubular fuel element that varies with position along the longitudinal axis. The ratio can vary with position along the longitudinal axis between a minimum of 0.30 and a maximum of 1.0. Increasing the ratio above and below the peak burn-up location associated with conventional systems reduces the peak burn-up and flattens and shifts the burn-up distribution, which is preferably Gaussian. The longitudinal variation can be implemented in fuel assemblies using fuel bodies, such as pellets, rods or annuli, or fuel in the form of metal sponge and meaningfully increases efficiency of fuel utilization.

  • Patent number: 10537262
    Abstract: A system for detecting a type of stroke includes a processing circuit. The processing circuit is configured to receive heart data regarding a heart rhythm of a patient and physiological data regarding a physiological characteristic of the patient. The heart data is indicative of an occurrence of atrial fibrillation and the physiological data is indicative of an occurrence of a stroke. The processing circuit is further configured to determine a likelihood that the stroke was an embolic stroke based on the heart data and to provide an output including an indication of the likelihood that the stroke was an embolic stroke.
