탄약 비군사화 심포지엄에 참석하여 안전하고 환경친화적인 불용탄 처리관련 기술현황을 분석하고 실제 운영중인 일부시설을 견학할 수 있었다. 또한 이 기간중 DAC의 주선하에 태평양지역 국가들의 회의 참석자들과의 별도 화합으로 Demil 정보를 교환하였다. 이와 같은 미국의 노력은 이 지역의 Demil 기술 종주국으로서 지도자 역할을 자임하려는 노력이 역력하였다. 현재 미국의 비군사화 사업은 대 테러전이 계속 진행됨에 따라 예산지원 우선순위에서 낮아져 향후 1-2년간은 사업규모의 축소 또는 지연이 예산된다. 따라서 정부내의 타부서와의 기술협력을 모색하여 기술개발은 꾸준히 이루어 질 것이다.

Various types of solid rocket motors which manufactured by each aim have their own shelf life. So they must be done away if not used. And inferior goods during manufacturing must be done away too. In the past, out burning and out detonation is usual but now, environmental pollution should be concerned so that there are related technologies and commercial plants in other countries already from 1970's. Hence in this paper, we will talk about foreign state and domestic development of solid rocket motor demilitarization using wash out.

향후 우리 군은 작전소요 등 특별한 경우를 제외하고는 불용탄의 야외처리를 단계적으로 축소하지 않으면 안 될 것이며 이에 대한 환경감시는 더욱 강화될 것이다. 뿐만 아니라 NIMBY 현상 등 지역 이기주의에 따라 현재기술로 가장 안전하다고 입증된 소각 대체기술로서 환경과 폭발안전을 도모할 수 있는 새로운 기술이 요구되고 있다.

Different kinds of solid rocket motors manufactured for various aim have their own shelf life. So they must be done away if not used. In general, ammonium perchlorate(AP) has used in the process of solid rocket motors, which is environmental pollutant. Out-burning and out-detonation were usual in the past, but they polluted the surrounding environment and raised safety issues. As an alternative to resolve these, water-washout process to separate the propellant from rocket motors and an eco-friendly way for recovering AP are studied in this paper.

The expiration date of high energetic materials(HEM), such as HMX, RDX, TNT, is important. If the expiration date is violated, the expected specification of HEM would not be satisfied which may cause a different conclusion in an urgent situation. As a result, this HEM should maintain fresh conditions which cause the accumulation of waste HEM. If HEM is landfilled during demilitarization, the impact on living organizations is serious. Additionally, landfilling HEM has a possibility of explosion. In this research, the process flow diagram of the demilitarization gas treatment process was simulated while satisfying the law of the environment in Korea. After validation of simulation, it was optimized thermodynamically using Heat Exchanger Network Synthesis(HENs). This study is expected to enhance the energy efficiency of the original facility by suggesting developed designs. This research was supported by Agency of Defense Development NE32 Korea.

The thermal decomposition of waste energetic materials such as TNT, RDX and composition B in a commercial rotary kiln has previously been carried out. As part of the demilitarization process, the thermal decomposition of homogeneous double base propellant (DB) used in M8 and consisting predominantly of nitrocellulose and nitroglycerine is examined with respect to a number of operating conditions. A single condensed phase reaction with 4 species and 365 gas phase reactions and 59 species are considered. Simulation results show the sensitivity of the thermal decomposition of DB with temperature and velocity. At relatively low velocity with constant inlet hot air temperature, temperature in the rotary kiln was found to be highest, 953 K and 1300 K for cases 3 and 6 respectively. Illustrating that optimum operating temperature can be achieved by controlling the inlet velocity without additional cooling systems.

Demilitarization involves the disposal and recovery of obsolete explosives or ammunition. Cyclotol has been used as a military explosive along with RDX and HMX. A limited number of processes exist for safe disposal due to their sensitivity to thermal shock. Rotary kilns are widely used for thermal decomposition in many countries due to cost effectiveness and simplicity compared with supercritical oxidation. Phase change as well as condensed phase reactions(CPRs) and gas phase reactions(GPRs) with rates described by the Arrhenius equation of cyclotol has been considered in this work. Changes in gas fraction, reaction rate and mass of explosives were predicted at 490, 505 and 575 K. A maximum temperature of 2062 K has been predicted within the reactor at an initial temperature of 575 K due to GPRs. From this research, Thermal decomposition in the rotary kiln is plausible for demilitarization.

Ammunition Demilitarization facility (ADF) should be set up the feasible goals and continue to operate, taking into account non-profit characteristics. However, due to the lack of performance measurement methods in ADF, which are essential to national policy at a significant cost each year, the reliability of the evaluation results can be insufficient. In this paper, the Balanced Score Card (BSC) method was applied that could be evaluated to reflect the financial and non-financial features. The relevant literature research and army regulations reflected the results of various interviews of the expert group. The extraction of success performance area in ADF was confirmed using the BSC method and the Decision Variable (DV) candidate was created to use regression for selecting the DV. Additionally, the key performance indicator was presented by verification the feasibility of content by conducting the survey of experts. The implications of this paper are as follows. First, the proposed BSC model was found to be suitable for practical use in ADF reflecting the non-profit characteristics. Second, accurate evaluation of ADF can contribute to long-term development of ADF. Finally, it can be applied to the management process of the other military sector, so it can be expected to play a role in providing basic data and spreading it to other areas.
