ABSTRACT:
A modular reactor head shielding system formed from a plurality of flexible pads shaped to interleave with the edges of each adjacent pad around the reactor head. The shielding system is assembled to protect workers from radiation exposure in working in the area around the reactor head or when working on the reactor head during refueling of the reactor. The pads are formed by inserting a pair of blankets secured to one another inside a pair of outer covers which are secured to one another in offset relation to form an interleave or tongue and groove configuration to eliminate radiation paths between pads. The blankets are formed by quilting lead wool within the blanket covers. Each pad has a hanging plate secured to one end which can be hung from a frame around a reactor head or from the reactor head itself. The pads are secured to one another such as with straps to insure elimination of radiation paths therebetween.
