Abstract

A thermal control system for a reactor pressure vessel includes a plate having a substantially circular shape attached to a wall of the reactor pressure vessel. The plates divide the reactor pressure vessel into an upper reactor pressure vessel region and a lower reactor pressure vessel region. Additionally, the plates are configured to provide a thermal barrier between the pressurized volume in the upper reactor pressure vessel region and the primary coolant in the lower reactor pressure vessel region. One or more plenums provide passage for a plurality of heat transfer tubes to pass through the wall of the reactor pressure vessel. A plurality of heat transfer tubes are connected to the plate.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 921,046, filed December 26, 2013, and US Non-Provisional Application No. 14 / 260,866, filed April 24, 2014. technical field [0003] The present application relates to the field of power generation, which relates to power systems including steam generator tube assemblies. Background technique [0004] Reactor performance, including the ability to efficiently generate electricity from the steam generators, can be altered or otherwise affected by various design considerations. For example, the number, length and wall thickness of the steam generator tubes can affect the decay heat removal and flow associated with the steam generator system. Similarly, the overall volume and wall thickness associated with the enclosure structure may determine, in part, the normal operating pressure or allowable system pressure of the power plant. [0005] In addition t...
