Thermal control system for nuclear reactor pressure vessel
The patent US12040097B2 describes a nuclear reactor system that features a reactor pressure vessel divided into upper and lower regions by a plate. This plate is equipped with an upper flange attached to the upper head of the vessel and a lower flange welded to its lower portion. The design facilitates the redirection of primary fluid flow from a riser downward within the vessel. The plate includes a tube sheet portion where heat transfer tubes are connected, extending into the lower region. Additionally, a plenum is situated in the upper region, allowing for the transfer of a secondary fluid between the heat transfer tubes and the external environment of the reactor pressure vessel.
Further claims detail the structural components and functionalities of the system. The heat transfer tubes are secured to the plate through corresponding holes in the tube sheet, and the plenum features a dome that extends over these holes. The design also includes provisions for conduits to facilitate fluid transfer, as well as multiple tube sheet portions and plenums for enhanced fluid management. The plate is constructed from low alloy steel and clad with stainless steel, ensuring durability. Auxiliary features such as surge flow holes, control rod drive shaft holes, and instrument guide tube holes are also incorporated, enhancing the reactor's operational capabilities. Overall, the patent outlines a comprehensive system aimed at improving fluid dynamics and heat transfer efficiency within nuclear reactor operations.
