Nuclear reactor core shroud

Patent ·
OSTI ID:4311080
A core shroud comprised of a plurality of vertically stacked cylindrical thermal shields resting on a core support plate is described. Horizontal plates closely conforming to the core shape are sandwiched between each thermal shield. The inner thermal shield sections have vertical plates in the form of angles welded to the interior in a manner generally conforming to the periphery of the core. An outer thermal shield surrounds each of the inner thermal shields. Vertical tie bolts located in the annular space between the two shields maintain a resiliently compressive force on the stacked array of thermal shields and horizontal plates. A core support barrel surrounds the shield and the structure has openings to permit downward flow of some of the coolant through the various annular spaces formed by the shields prior to passage of coolant through the core.
