EXAMINATION OF SHIPPING PACKAGE 9975-2130

[摘要] Shipping package 9975-02130 was examined in K-Area following the identification of a nonconforming condition; the axial gap between the drum flange and upper fiberboard assembly exceeded the maximum allowed value of 1 inch. The average measured axial gap was 1.1 inches. The fiberboard assembly in this package contained moisture levels of {approx}14-24% wood moisture equivalent ({approx}12-19 wt%) This is moderately higher than typically seen in conforming packages, but not as high as seen on most packages which have exceeded the allowed axial gap. Small patches of mold were growing on portions of the lower fiber assembly, but the fiberboard appeared intact and with little apparent change in its integrity. The lead shield had a heavy layer of corrosion product, some of which flaked off easily. The thickness of several flakes was measured, and varied from 0.0016 to 0.0031 inch. However, additional corrosion product remained on the shield under the flaked regions, so the total thickness of corrosion product exceeds 0.0031 inch.
