Title: Examination of Shipping Package 9975-04194

Abstract

In December 2017, K-Area personnel attempted to open package 9975-04194 to remove its contents. The upper fiberboard assembly could not be initially removed due to an interference fit that had developed against the lead shield. Corrosion of the shield created two specific conditions that caused this interference. First, there was widespread heavy blisters over the shield surface. Corrosion of the lead under the surface (associated with porosity in the as-cast shield which is open to the surface) appears to have caused the blisters to form. Second, corrosion also formed in a gap between the lead shield and the internal stainless steel liner, pushing the top edge of the shield outward into the upper fiberboard assembly. In both cases, portions of the shield are pushed outward since the corrosion product occupies a greater volume than the metallic lead it replaced.
