【 摘 要 】

Repositories have been in use at Lawrence Livermore National Laboratories for storage of ten grams or less explosives samples for about twenty years. A previous Repository testing program detailed in UCID 19219 reported that a standard repository would contain ten grams of high explosive but the repository drawer would open. It further recommended a non-propagating array that would allow storage of quantities of explosives in a repository drawer, however; the capability of the proposed nonpropagating array was never verified. A series of tests was undertaken to verify the capability of the proposed array to provide non-propagation between 10-gram samples stored within that array and to document the extent of damage to the stored explosives, the array and the repository. Testing has verified that the standard four-drawer repository configured per UCID 19219 may store a 10-gram explosive sample without propagation to the other materials stored in the repository. Should a detonation of a 10-gram sample occur, the four-drawer repository will be damaged but does not appear to create a significant fragment hazard and does not sustain significant damage. The drawer containing the test charge opens quickly and fully releasing the detonation overpressure. Testing of a standard two-drawer repository verified that the array will prevent propagation, however; the repository was totally destroyed and would present a physical hazard to personnel and equipment in the immediate area of the repository. An additional test of a standard repository was conducted to verify current storage practices for detonators using detonators in the Mound non-propagating packing configuration. The repository drawer tested sustained minimal damage and no propagation between stored detonators. Therefore, storage of detonators in a standard Mound or Manufacturer non-propagating configuration in either a two-drawer or four-drawer repository is acceptable.
