Earth Covered Ammunition Storage Magazines Quantity-Distance Model, DISPRE2
Abstract
The building debris hazard prediction model DISPRE has been expanded under an international KLOTZ Club sponsored program. The new version of the model, DISPRE2, covers arch-shaped and rectangular above-ground ammunition magazines storing up to 5,000 kg of TNT equivalent explosives material. Quantity-distance criteria for ammunition magazines have historically been based on the analysis of test data. The tests are usually conducted to expose magazines of specific designs to internal detonations, measure the external blast, and map and analyze the structural debris and weapon fragments. Fragment and debris critical densities are calculated and then used to define safe siting distances between two magazines and between a magazine and an inhabited building or public traffic route. Quantity-distance criteria are set in this way for directions to the front, side, and rear of a donor magazine. When a new magazine design is developed or an existing design is modified, additional testing (scale model or prototype) may be necessary to officially site the magazine. This approach is quite costly, in terms of financing the tests and efficiently getting approval of the design and constructing the new magazines. A more economical and feasible approach is to have a computer model, validated with available data, which can be used to predict the debris density at any given distance from the magazine. A predictive model for determining safe siting distances for protection from hazardous building debris was developed by Southwest Research Institute (SwRI) in recent years under funding from the U.S. Department of Energy (DOE) with additional contributions from the U.S. Department of Defense Explosives Safety Board (DDESB). This model, termed DISPRE for "dispersion prediction", was approved as a siting tool for explosives processing or handling facilities in November 1990 by both DOE and DDESB.
