Pivotably mounted reactor shroud shield.

摘要

Shielding for technicians working around a nuclear reactor during the refueling process is provided by permanently mounted shield supports arranged around the reactor shroud and adapted to support shielding members such as lead panels. The shield support includes a permanent rail encircling the shroud and swingout arms which are pivotably mounted to the permanent rail. During use the shielding members are positioned adjacent the swingout arms by a stud tensioner hoist, and the swingout arms are pivoted outward to receive the shielding members. When installed, the shielding members overlap at their edges.
