Title: Ceramic nuclear fuel dispersed in a metallic alloy matrix
Inventor: LEON C WALTERS
IPC: G21C21/16
Filed: 2015-04-07
Abstract: Systems and methods for manufacturing metal fuel are described. Methods for fabricating a metal-fuel-matrix cermet nuclear fuel may include crushed ceramic particles combined with metallic fast reactor fuel via bottom pour casting or injection casting, or a powdered metallurgical process. A maximum quantity of crushed ceramic particles added to the metallic fuel must not exceed that which would fail to yield a continuous matrix of metal fuel. After a short irradiation period, the microstructure of the fuel may be substantially identical to that of injection cast fuel, without crushed ceramic particles, irrespective of the fabrication process. Thus, the extensive existing database for injection cast fuel, without crushed ceramic particles, may be an excellent indicator of expected irradiation performance. Each of the processes may contribute to a solution of the spent nuclear fuel problem and may denature Pu239 during the process.

Title: Methods and apparatus for particle aggregation using acoustic standing waves
Inventor: JR Walter M Presz
IPC: C02F1/36
Filed: 2016-03-24
Abstract: Devices for separating materials from a host fluid are disclosed. The devices include an acoustic chamber, the figure indicates the view perpendicular to an ultrasonic transducer (130), having an inlet at the bottom and an outlet at the top. The ultrasonic transducer (130) and reflector create a multi-dimensional acoustic standing wave in the acoustic chamber that traps the materials and permits a continuous separation of the materials from the host fluid (vertical flow direction 120). The materials and the host fluid can thus be separately collected. Multiple sets of trapping lines (132) are generated by the acoustic standing wave, and the transducer (130) is oriented or has a shape to minimize cross-sectional area for straight vertical channels between the trapping lines.

Title: Security configuration determination
Inventor: MARK SHACKLETON
IPC: G06F21/55
Filed: 2017-11-07
Abstract: This application is for a method of determining a security configuration for a target virtual machine (VM) by training a machine learning algorithm. It works by first training the machine learning algorithm to determine a vector of security vulnerabilities for the target VM based on a vector of configuration characteristics 802. The machine learning algorithm is trained using training examples that include an identification of a set of security configurations for a training VM. It then selects a subset of these 804, and executes the machine learning algorithm with the vector of configuration characteristics to generate a set of vulnerability vectors for each security configuration in the selected subset 806. Finally, it selects a security configuration for the target VM based on the set of vulnerability vectors 808. The method may also include receiving an indication of one or more security threats affecting the target VM, and selecting a security configuration based on this threat.
