A steam dispersion system including insulation is disclosed. The steam dispersion system may include a steam dispersion tube with at least one opening defined on an outer surface of the steam dispersion tube and a hollow interior. The insulation covers at least a portion of the steam dispersion tube, the insulation defining an opening aligned with the opening of the steam dispersion tube, wherein the insulation meets 25/50 flame/smoke indexes for UL723/ASTM E-84 and has a thermal conductivity less than about 0.35 Watts/m-K (2.4 in-hr/ft{circumflex over ()}2 deg F.). A nozzle defining a throughhole may be placed within the opening of the steam dispersion tube, the throughhole being in fluid communication with the hollow interior of the steam dispersion tube to provide a steam exit.

A vibration-inhibiting bar is provided that is interposed between bends of the tubes of two adjacent banks of tubes of a U tube bundle of a steam generator and includes at least one internal element, referred to as a damping element, designed to mechanically damp the vibrations of the tubes; and at least one external element, referred to as percussion element, in contact with the damping element, the percussion element being designed to be in contact with the bends of the tubes of the bundle.

A steam generator that reduces the thermal and hydraulic unevenness in the steam generator, improves the filling capacity of the steam generator with heat exchange tubes, organizes an economizer portion of the heat exchange surface in the steam generator, and reduces the concentration of corrosive impurities in the weld zone of the primary circuit to the horizontal shell. To solve the task in such steam generator containing the horizontal shell and other component, the heat exchange tubes are located in vertical planes, and the inlet and outlet manifolds of the primary circuit are arranged horizontally. The steam generator can also be equipped with at least two output manifolds of the primary circuit furthers, the feed water dispenser can be located below the heat exchange tubes of the steam generator.

A robotic system includes a processing system comprising at least one processor. The processor generates a plan to monitor the asset. The plan comprises one or more tasks to be performed by the at least one robot. The processor receives sensor data from at least one sensor indicating one or more characteristics of the asset. The processor adjusts the plan to monitor the asset by adjusting or adding one or more tasks to the plan based on one or both of the quality of the acquired data or a potential defect of the asset. The adjusted plan causes the at least one robot to acquire additional data related to the asset when executed.
