Project summaryDeveloping environmentally benign and safe technologies for HE reclamation from ammunition and applications in the national economy is a topical problem that arises from large-scale retirement and disposal of certain types of ammunition. Ammunition dismantlement is currently performed in parts and followed by having HE components disposed of through detonation or incineration. This is what results in the environmental impact and potential energy of explosives and national raw resources being spent waste fully.
The goal of the Project to develop an environmentally clean and safe technology to recycle HE components removed from retired ammunition units.
The objective of the Project is to develop a new technology that allows production of HE crumbs by machining operations including hydropresses crushing HE parts, roll milling, and turn grinding.
The proposed way to recycle HE parts using the VNIIEFs available engineering capabilities along with over the commonly known and published recycling techniques (cryogenic, hydraulic, chemical, etc.) is easily realized.
The main principles of this utilization technique are based on opportunity of technical its realization, practical expediency, agreement with economic and ecological requirements.
Technical and economic investigations testify that:
- application of technological facilities, available in VNIIEF (such as presses, roll mills, molding, tools, etc.), technological documentation, intellectual potential o! VNIIEF experts provides peaceful alternative opportunities to a group of weapons scientists, requires no additional financial contribution for development of пек facilities, building of пек premises, staff training;
- method of mechanical processing of HE details is adopted in study practice of VNIIEF Department for High-explosives Chemistry and Technology. The model of mechanical processing of HE details, developed on the basis of scientific investigations, is unified for all HE, used in the industrial application. This model is based on justified safety criteria (such as specific crash pressure, interroll spacing, turning rate, etc.). It can be used in full measure in technology of HE details reprocessing. Scientists and technical staff, involved in the Project activities, have high professional skill and large experience of conduction of similar works for military application;
- according to experts, recycled HE will cost -50% of the commercially produced HE;
- capacity achieved per equipment unit in a shift is about 30-50 kg of HE crumbs;
- recycled HE has its physical and chemical properties, process efficiency and other characteristics not inferior to its commercially produced analogs. It can be employed widely in commercial applications (for example, in shooting perforation equipment for oil and gas industry and other industries). Exchange of ammunition HE for recycled one allows saving source of raw materials;
- safety of the environments and people he a If is the important aspect of the proposed technique to recover HE from ammunition.
The Project's purpose is consistent with the ISTC objective to contribute to conversion process toward market economy development, shift the efforts of mass destruction weapons scientists, support fundamental and applied non-defense K&D, including environmental science.
The Project offers commercial potential, since it will allow the use of reclaimed HE in such applications as shooting perforation equipment for oil and gas industries or borehole charges for quarry and other mining operations, and provides a long-term career opportunities to the Institute scientists.
To solve these tasks successfully arid then to use results of the works in practice, we are interested in active participation of foreign partners m all stages of the Project, including participation in discussions on (lie main directions and scope of the Project activities, help in delivery of needed equipment, exchange of information, discussions of results obtained after fulfillment of each task on workshops, commercialization of these results with the purpose to bring, them to the market, joint publications, participation in scientific conferences.
The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.
ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
