Abstract: A riser cone has a lower end sized to engage a cylindrical lower riser section of a nuclear reactor and an upper end sized to engage a cylindrical upper riser section of the nuclear reactor. The riser cone defines a compression sealing ring that is compressed between the lower riser section and the upper riser section in the assembled nuclear reactor. In some embodiments the riser cone comprises: a lower element defining the lower end of the riser cone; an upper element defining the upper end of the riser cone; and a compliance spring compressed between the lower element and the upper element. In some embodiments the riser cone comprises a frustoconical compression sealing ring accommodating a reduced diameter of the upper riser section as compared with the diameter of the lower riser section.

Abstract: Organizing data where the data has spatial significance. A method includes, at a user interface, displaying to a user a representation of spatially structured data. User input is received at a computer implemented user interface through one or more hardware user interface devices. The user input is domain agnostic, but has a spatial connotation. Based on pre-existing structured data displayed at the user interface, a domain is determined for the user input. Based on the determined domain, the user input is interpreted into a domain specific response. The domain specific response is consistent with the spatial connotation across a plurality of domains.

Abstract: Various technologies described herein pertain to controlling a game with a mobile touch-enabled device. A thumbstick and a mode selection button can be rendered on a display of the mobile touch-enabled device. The thumbstick can be rendered on a reassignable area of the display and the mode selection button can be rendered on a mode selection area of the display. A touch (e.g., drag) from the mode selection area to the reassignable area can be detected, and an operation in the game can be controlled with the thumbstick represented as being at a depressed height in response to the touch in the reassignable area while the touch is detected without discontinuity of contact from starting the drag. Further, upon detecting discontinuation of the touch, a different operation in the game can be controlled with the thumbstick represented as being at a default height in response to a subsequent touch.

Abstract: A nuclear island includes a nuclear reactor, a lateral seismic restraint, and an in-vessel reactor core retention cooling system. The lateral seismic restraint includes a vertically oriented pin attached to one of the bottom of the lower vessel head and the floor underneath the nuclear reactor, and a mating pin socket is attached to the other of the bottom of the lower vessel head and the floor. The in-vessel reactor core retention cooling system includes one or more baffles, optionally thermally insulating material, disposed alongside the exterior surface of a lower portion of the reactor pressure vessel including at least the lower vessel head. A plenum is defined between the one or more baffles and the exterior surface of a lower portion of the reactor pressure vessel. The one or more baffles may define a lower plenum inlet surrounding the lateral seismic restraint.

Abstract: A nuclear reactor includes a reactor core disposed in a reactor pressure vessel. A radiological containment contains the nuclear reactor and includes a concrete floor located underneath the nuclear reactor. An ex vessel corium retention system includes flow channels embedded in the concrete floor located underneath the nuclear reactor, an inlet in fluid communication with first ends of the flow channels, and an outlet in fluid communication with second ends of the flow channels. In some embodiments the inlet is in fluid communication with the interior of the radiological containment at a first elevation and the outlet is in fluid communication with the interior of the radiological containment at a second elevation higher than the first elevation. The radiological containment may include a reactor cavity containing a lower portion of the pressure vessel, wherein the concrete floor located underneath the nuclear reactor is the reactor cavity floor.

Further, upon detecting discontinuation of the touch, a different operation in the game can be controlled with the thumbstick represented as being at a default height in response to a subsequent touch.

Abstract: Various technologies described herein pertain to utilization of shared Wi-Fi. For instance, network access rights of a Wi-Fi network can be controlled by a mobile device of a point of contact for the Wi-Fi network. Moreover, utilization of a Wi-Fi network can be tracked and usage data indicative of historic utilization of the Wi-Fi network can be retained. Further, groups of users between whom Wi-Fi credentials are shared can be created.

Abstract: Various technologies described herein pertain to sharing Wi-Fi credentials based upon relationships in a computer-implemented social network. At least one server computing device of a Wi-Fi credential sharing service receives an identifier from a mobile device and credentials for a Wi-Fi network from the mobile device. The identifier identifies a user of the mobile device. Moreover, the credentials for the Wi-Fi network are desirably shared by the user. Further, contacts of the user are retrieved from the social network. The credentials for the Wi-Fi network are retained in respective accounts of the contacts of the user from the social network. Further, an account of a contact includes credentials for Wi-Fi networks shared with the contact.

Abstract: A method includes transmitting an interface to a display device, where the interface represents a view of at least a portion of a graph. The graph is based on a model of a system and includes a plurality of nodes connected by a plurality of links, where at least one node of the graph includes another node. The method includes receiving a command to store a placemarker corresponding to the view and storing the placemarker. The placemarker is selectable to restore the view at the interface.
