Abstract:
A traveling wave nuclear fission reactor, fuel assembly, and a method of controlling burnup therein. In a traveling wave nuclear fission reactor, a nuclear fission reactor fuel assembly comprises a plurality of nuclear fission fuel rods that are exposed to a deflagration wave burnfront that, in turn, travels through the fuel rods. The excess reactivity is controlled by a plurality of movable neutron absorber structures that are selectively inserted into and withdrawn from the fuel assembly in order to control the excess reactivity and thus the location, speed and shape of the burnfront. Controlling location, speed and shape of the burnfront manages neutron fluence seen by fuel assembly structural materials in order to reduce risk of temperature and irradiation damage to the structural materials.
Abstract:
A nuclear fission reactor, flow control assembly, methods therefor and a flow control assembly system. The flow control assembly is coupled to a nuclear fission module capable of producing a traveling burn wave at a location relative to the nuclear fission module. The flow control assembly controls flow of a fluid in response to the location relative to the nuclear fission module. The flow control assembly comprises a flow regulator subassembly configured to be operated according to an operating parameter associated with the nuclear fission module. In addition, the flow regulator subassembly is reconfigurable according to a predetermined input to the flow regulator subassembly. Moreover, the flow control assembly comprises a carriage subassembly coupled to the flow regulator subassembly for adjusting the flow regulator subassembly to vary fluid flow into the nuclear fission module.
Abstract:
Solutions for limiting the undesirable spread of pathogens by indirect contact are provided. The solutions involve event-controlled self-sterilization of contact surfaces on articles or fixtures. A self-sterilizing contact surface structure allows chemical sterilizing agents to controllably flow in response to a contact event, from within the article to exude upon a portion of the contact surface.

Abstract:
A nuclear fission reactor fuel assembly adapted to permit expansion of the nuclear fuel contained therein. The fuel assembly comprises an enclosure having enclosure walls to sealingly enclose a nuclear fuel foam defining a plurality of interconnected open-cell voids or a plurality of closed-cell voids. The voids permit expansion of the foam toward the voids, which expansion may be due to heat generation and/or fission gas release. The voids shrink or reduce in volume as the foam expands. Pressure on the enclosure walls is substantially reduced because the foam expands toward and even into the voids rather than against the enclosure walls. Thus, the voids provide space into which the foam can expand.
Abstract:
Systems described herein include integrally sealed containers. An integrally sealed container may include one or more segments of a first ultra efficient insulation material having one or more surface regions, the one or more segments principally defining at least one storage region; and one or more regions of substantially thermally sealed connections between at least one of the one or more surface regions of the one or more segments wherein the one or more regions of substantially thermally sealed connections and the one or more segments form an integrally thermally sealed storage region.
Abstract:
Systems include one or more storage containers. A container may include one or more segments of a first ultra efficient insulation material shaped to define at least one substantially temperature-stabilized storage region, and an access region, including at least one region of the one or more segments of ultra efficient insulation material configured for at least one perforation by a perforation device, wherein one or more of the at least one perforation is configured to provide for a controlled egress of a discrete quantity of material from the at least one storage region.
Abstract:
Methods and related systems for modulating neural activity by repetitively or cyclically blocking conduction in a peripheral neural structure are disclosed. Timing of delivery of blocking stimuli may be based upon overall activity level of the subject or use/activity of a portion of the body of a subject.
