Abstract: The present disclosure provides an integrated head package for a nuclear power generation system, the integrated head package comprising a closure head, and a control rod drive mechanism housed within a shroud. The control rod drive mechanism comprises at least one drive rod extending through the closure head and having a coupling element for releasably coupling to a control rod assembly within a reactor core. The at least one drive rod is movable to a maintenance/refuelling position in which the at least one drive rod is uncoupled from the control rod assembly and at least partially retracted into the integrated head package. The integrated head package further comprises at least one engagement feature for securing the at least one drive rod in the maintenance/refuelling position.

Abstract: Gaming systems that in various embodiments provide for each of a plurality of pots, when the activator occurrence indicator(s) associated with that pot reach a pot conversion level for that pot, the occurrence of the activator associated with that pot causes an enhancement of the feature associated with that pot. Gaming systems that in various embodiments provide for each of a plurality of pots, when the activator occurrence indicator(s) associated with that pot reach a pot conversion level for that pot, the occurrence of the activator associated with that pot causes that pot to switch from a perceived persistence pot to an actual persistence pot such that a subsequent activator associated with that pot can automatically cause an activation of that pot.

Abstract: Disclosed is a nuclear power generation system comprising a reactor vessel comprising a body defining a cavity housing a reactor core, and an integrated head package having a closure head for closing an opening to the cavity. The system also comprises a containment structure having a working floor surrounding and substantially vertically aligned with the opening to the cavity.

Abstract: Gaming systems and methods configured to independently generate, display, and provide different full and partial features in association with different activators during plays of a game. If the gaming system determines not to provide the full feature associated with a pot based on an occurrence of the activator associated with that pot, the gaming system determines whether to provide a partial feature associated with that pot. The gaming system is also configured to, for each partial feature to determine how many plays of the game to provide the partial feature for.

Abstract: Gaming systems and methods configured to display, for one more of activations of the symbol displays for a play of a game, an automatic activation zone associated with the symbol displays. For the play of the game: (a) if an activator is displayed on one of the symbols displays at the automatic activation zone, the gaming system automatically activates the pot associated with that activator and thus the feature associated with that pot; and (b) if an activator is displayed on one of the symbols displays not in the automatic activation zone, the gaming system randomly determines whether to activate the pot associated with that activator and thus the feature associated with that pot. In either activation case, the activated feature can then be used for one or more subsequent activations of the symbol displays.
