The reactor vessel assembly, shown on page 3-4, consists of the reactor vessel and its internal components, including the core support structures, core shroud, moisture removal equipment, and jet pump assemblies. The purposes of the reactor vessel assembly are to: • House the reactor core, • Serve as part of the reactor coolant pressure ...
