ABSTRACT:
A modular radiation shielding system for use on the lower side of a nuclear steam generator tubesheet 14 to protect inspection and repair workers in the primary head 20 of the generator 10 from radiation of the tubesheet 14 and plurality of tubes 12 it secures. The modular assemblies each comprise a geometrically shaped lead panel 22 sheathed in a stainless steel box 30 with a transverse opening extending therethrough for alignment with a tube 12. A rapid installation tube gripper 40, which may have a lead nose for shielding, extends through the opening and into a tube 12 to hold the geometrically shaped modular assembly against the lower surface of the tubesheet 14.
