Abstract: A method of releasing an atmospheric effluent within a nuclear containment to an atmosphere surrounding the nuclear containment is disclosed. The nuclear containment is adjacent to an associated spent fuel pool that is located outside the nuclear containment, the method comprises sensing a pressure buildup within the nuclear containment, routing a portion of the atmospheric effluent through the spent fuel pool when a pressure buildup within the nuclear containment reaches a preselected value, and releasing a chemical into the spent fuel pool, based on the routing, to facilitate a reaction with the atmospheric effluent to substantially neuter any deleterious environmental impact of the atmospheric effluent.

Abstract: A nuclear containment atmospheric filter including dedicated piping, valves, a control system and a chemical injection system to facilitate the use of a commercial nuclear power plant's Spent Fuel Storage Pool and Spent Fuel Storage Pool Cooling System to filter and cool contaminated air and steam vapor released from within a Reactor Containment Vessel/Building preventing vessel overpressure and radioactive release.

Abstract: Techniques are provided for providing assistance to users in locating and accessing points of interest associated with particular time positions in the media items using the techniques described herein. For instance, an electronic device outputting a media item may select one or more metadata items based on a current output position in the media item. The electronic device may then generate and output a user interface including a progress bar that includes indicators representing the selected metadata items and output the user interface to a display of the electronic device.

Abstract: Systems and methods are provided for determining user interface controls associated with hierarchical levels during media content playback. In some embodiments, instructions may be provided to display user interface controls associated with a level of media content, such as a chapter level. A change in the level of media content and/or the user interface controls associated with the level may be a response to a level change request. A level change request may be initiated by user input and/or may automatically be initiated by the current content playback position.

Abstract: Features are disclosed for facilitating content presentation and consumption based on input regarding a user's gaze. Gaze tracking or eye tracking information can be obtained from, e.g., a user-facing camera. A content presentation system can determine whether the user's eyes have closed and how long they have closed, whether the user's gaze is directed at the portion of content currently being presented or at some other location, etc. Based on such determinations, presentation of content may be modified. In some cases, a current presentation position may be changed, highlights may be applied, a special bookmark may be generated, etc.
