摘要

Disposal of time expired and unexploded ordnance is a significant challenge. Sea dumping has long since been prohibited and hence other disposal methods have been considered and continue to be explored. Incineration of life expired or surplus munitions is expensive due to infrastructure costs, meeting the emission requirements from furnaces and the limitation of the quantity of explosives in the furnace. Open burning or detonation is therefore still used as a disposal method and is more appropriate for unexploded ordnance, when access and movement of the device is limited. Simply attaching and firing an explosive charge fastened to the case, causing the device to function often requires wide exclusion and collateral damage zones. Firing remote devices at unexploded ordnance, penetrating the case and inducing deflagration in the explosive filling, reduces the potential damage zone and has been successfully employed. This is often achieved using solid shot penetrators and shaped charges driven by high explosives. Some of these devices require the operator to estimate the performance to achieve deflagration rather than detonation. These methods depend on the use of explosives which require to be stored and transported prior to use and this has both costs and logistics implications. A student project has therefore been carried out to explore how a non explosive liquid could be utilised to achieve a similar deflagration effect on unexploded ordnance. Nitromethane, a combustible non-explosive liquid, can be rendered detonator sensitive by either chemical or physical treatment. Both methods have been explored and compositions produced, which are easy to manufacture and field fill, and can reliably initiate deflagration in munitions containing typical high explosive fillings. The raw materials need no special arrangements for prior storage and transportation and once the mixture is prepared it is both safe to use and can be safely disposed of if not used. Further development will examine improved storage stability of the field filled charge, and will consider the practical implication of use for EOD consideration or for disposal of surplus munitions.
