Test Report for Perforated Metal Air Transportable Package (PMATO) Prototype.

Abstract

A prototype design for a plutonium air transport package capable of carrying 7.6 kg of plutonium oxide and surviving a "worst-case" plane crash has been developed by Sandia National Laboratories (SNL) for the Japan Nuclear Cycle Development Institute (JNC). A series of impact tests were conducted on halfscale models of this design for side, end, and comer orientations at speeds close to 282 m/s onto a target designed to simulate weathered sandstone. These tests were designed to evaluate the performance of the overpack concept and impact-limiting materials in critical impact orientations.The impact tests of the Perforated Metal Air Transportable Package (PMATP) prototypes were performed at SNL's 10,000-ft rocket sled track. This report describes test facilities calibration and environmental testing methods of the PMATP under specific test conditions. The tests were conducted according to the test plan and procedures that were written by the authors and approved by SNL management and quality assurance personnel. The result of these tests was that the half-scale PMATP survived the "worst-case" airplane crash conditions, and indicated that a full-scale PMATP, utilizing this overpack concept and these impact-limiting materials, would also survive these crash conditions.

Radiant heat test of Perforated Metal Air Transportable Package (PMATP).

“…These investigations include laboratory tests on the component materials, field impact tests on half-scale models, and thermal analyses of the package in both undamaged and a suite of post-impact states. 4,5 This report presents results from a thermal test of the full-scale package in its undamaged condition and compares these test measurements with finite element simulations. The test is intended to simulate a one-hour aviation fuel fire.…”
