Resolution of Generic Safety Issues: NMSS-0012. Inadequate Transportation Packaging Puncture Tests (Rev. 1) ( NUREG-0933, Main Report with Supplements 1–34 )
This issue was identified when two holders of Certificates of Compliance for shipping packages performed puncture tests using a bar that was not properly mounted, as specified in 10 CFR 71.73(c)(3). As a result, NRC Bulletin 97-021714 was issued to to holders of Certificates of Compliance for shipping packages under 10 CFR 71 with the request to review puncture test assessments for each certified package design. For designs based on physical tests, certificate holders were requested to determine whether the puncture tests were performed in accordance with 10 CFR 71.73(c)(3).
The responses to the Bulletin1714 identified packages that had not been puncture-tested in full accordance with the regulations. In addition, there were some packages for which the certificate holders were unable to determine whether the tests were performed correctly. In these cases, the certificate holders submitted justification for continued use of their packages.
This issue was given a medium priority ranking and resolution was pursued.1709 In response to Bulletin 97-02,1714 some certificate holders retested their packages to demonstrate adequacy. It was determined that, even though previous tests had not been performed exactly as specified in the regulations, the differences had no significant effect on the test results. Based on these findings and the excellent safety record for these packages, the staff concluded that no further action was needed with respect to previously-approved packages. These packages were authorized for use under certain restrictions pursuant to 10 CFR 71.13. Thus, the issue was resolved.1771
