By development of dissolvable technique and equipment for warhead, empty cartridge and ammunition in small caliver, pollution of environment and waste of resources problems brought by existing incinerative abrogation can be fundamentally prevented. In addition, Automatic high-speed mechanically dissolving technique using indexing equipment developed in this study makes possible curtailment of manpower and recycling treatment of recources.

There are many one-shot devices that are used once and thrown away. One-shot devices such as firecrackers and ammunition are typical, and they are stored for a while after manufacture and then disposed of after use when necessary. However, unlike general operating systems, these one-shot devices have not been properly evaluated. This study first examines what the government does to secure reliability in the case of ammunition through ammunition stockpile reliability program. Next, in terms of statistical analysis, we show what the reliability analysis methods are for one-shot devices such as ammunition. Specifically, we show that it is possible to know the level of reliability if sampling inspection plan such as KS Q 0001 which is acceptance sampling plan by attributes is used. Next, non-parametric and parametric methods are introduced as ways to determine the storage reliability of ammunition. Among non-parametric methods, Kaplan-Meier method can be used since it can also handle censored data. Among parametric methods, Weibull distribution can be used to determine the storage reliability of ammunition.

The waste ammunitions have been accumulated in excessive amounts these days. This study focused on the problems related to the method of ammunition disposal which leads the explosion inside the enclosure structure and controls the effects of detonation. This study enables us to design a new type of explosive disposal facilities that would fit to our environments. And this study gives us the prototype design of the explosive disposal structure that are explored in this research and will give us a chance to develop a new type structure that have not been devised by Army, and also will be applicable to construct a civilian explosive disposal structure located in airports, harbors, and public facilities.

We studied the financial performance of ammunition stockpile reliability program on the Defense Management. We proposed the direct effect analysis, the indirect effect analysis and the combat power reinforcement effect as the financial performance analysis methodology. And, we estimated the financial performance using the proposed methods and the data of 2013 ASRP's data The financial performance by direct effect and indirect effect analysis was 99.96billion won and 303.7billion won. Also, The financial performance by reinforced Combat power reinforcement was 12.06 billion won. Therefore, the total financial performance of Ammunition Stockpile Reliability Program was 52.43 billion won.

Waste explosives such as useless ammunition discharged from the military and coproduced useless explosives during the manufacturers production process have been continuously produced. These are difficult to dispose with normal waste treatment facilities due to the dangers of fire and explosion. An open burning or an open detonation at military designated disposal facilities is a classical treatment method for the dangerous explosives. The classical method raises various environmental problems by the emission of hazardous materials. An air pollution by the emission of hazardous gases such as SO_x and NO_x, soil and water contaminations by the accumulation of non-biodegradable heavy metals, are representative pollution examples. To overcome these problems, various processes for eco-friendly waste treatment methods have been developed, and some processes have already been operated in some countries. In the current report, various eco-friendly disposal processes for waste explosives or harmful materials, and their advantages and disadvantages are documented to suggest future development directions for reducing the hazardous substances by the treatment processes.

Currently, researches on recycling and reuse of waste energetic materials have recently gained a great attention from advanced countries due to ever tightening environmental regulations. In this study, as a part of a recycling technology, the experiments and dynamic simulation of simulated moving bed (SMB) process were performed to efficiently separate TNT and RDX from their mixture, which are main components of ammunition. In order to determine the operation zone of SMB process, the retention times of TNT and RDX were measured using HPLC at different flow rates and the adsorption equilibrium of each component was obtained by using a moment method. According to the adsorption equilibrium and the triangle theory of SMB process, four operation points were determined and separation experiments were carried out by the SMB process using the solvent consisting of acetonitrile and water. Two different mixing ratios (6:4 and 1:1) of acetonitrile and water were chosen for the experiment due to the great impact of mixing ratio of the solvent on separation. The performance of SMB process was evaluated by purity, recovery, productivity and solvent consumption. Pure TNT and RDX were successfully obtained from the SMB process and the dynamic simulation for the SMB process agreed well with the experimental results. Therefore, the dynamic model could be applied for predicting the dynamic behavior of the SMB process and designing a large scale SMB process.
