Tungsten T-Flex® was selected as the best material to shield divers during a Steam Dryer repair.   Approval for use in flood up water required chemical testing for leachables and heavy metals.  The end result was an 8 ft X 5 ft shield wall constructed by attaching T-Flex panels to a metal frame.  Each side of the frame had 8 ft X 1.5 ft stationary panels.  The middle had several removable T-Flex ‘windows’ hanging on hooks to allow work access in the center. The shield panels are 0.56 inches thick and provide and approximate 42% dose reduction at C0-60 energy.
