Abstract
Drop and puncture tests conducted on a 1/4 scale model of the NuPac 125 B Fuel Shipping Cask are described and the correlation between test results and analytical predictions discussed. The NuPac 125B cask will be used to transport canisters of Three Mile Island Unit 2 (TMI-2) fuel debris, and provides two levels of testable containment for the canisters. The tests verified that the package can survive the impact hypothetical accident conditions specified in 10CFR71.73, provided experimental data on accelerations and strains, and defined the accident damage as initial conditions for other analyses. Three 30-ft. drop tests and two 40-in. drops onto a puncture bar were performed. The 30-ft. drop tests consisted of one end drop onto the bottom impact limiter, an oblique drop onto the closureend impact limiter, and a flat drop onto the side of the package. The 40-in. puncture tests were directed at the side and closure end of the package. Additional test activities included measurement of critical package dimensions and leak testing.
