Several contractors gave briefings to the committee about their capabilities and experience, while others provided answers to written questions. Finally, the committee confirmed its understanding of the technologies in this chapter with PD Demil or the appropriate vendors to ensure that the information presented in this chapter is accurate. The organizations providing information to the committee are listed below. Some of these organizations have additional munitions demilitarization capabilities; however, these are the primary ones that the committee has considered. Alternatives for the Demilitarization of Conventional Munitions. These studies were carried out over the past 30 years by various organizations and government agencies. They are listed in the references to this chapter. In several of the reviewed studies, alternative technologies are grouped with respect to their role in the munitions demilitarization process.

Typical technology groupings include munitions pretreatment and disassembly, energetics removal, munition or energetics destruction, pollution abatement, and resource recovery and recycling. While the committee did not contact every commercial vendor involved in the demilitarization of conventional munitions, the committee believes that it has examined and discussed existing capabilities with the primary commercial providers currently engaged in this activity. In the technology review conducted in this chapter, both those technologies that are capable of demilitarizing munitions in a single processing step and those that partially process the munitions are described.

This is only a partial compilation; numerous other treatment processes exist and have been evaluated in several of the reports listed in the references to this chapter—for example, Poulin and Wilkerson However, the technologies described below are those that have been demonstrated or permitted in the United States where permits were required and, in general, have a greater level of maturity than other technologies. The distinction between technologies capable of demilitarizing whole munitions and those that do partial munition processing is somewhat arbitrary; a technology that is capable of processing an entire munition of one type may require one or more preprocessing steps prior to demilitarization for a munition of another type—for example, a larger or more complex munition.

Several of the technologies described have dual capabilities in that they can perform the contained burning of munition energetics and propellants but also have explosive containment capabilities; thus, they can function as contained detonation chambers as well. Where these capabilities exist, they are so noted. For many munitions it is not feasible to demilitarize the whole munition using a single alternative technology due to technical, safety, environmental, or cost issues. Examples of such munitions include large bombs, complex cartridges containing submunitions such as grenades and bomblets, and munitions containing shaped charges that could damage containment chambers. Where this is the case, technologies that perform a partial function—for example, those that only reduce munition size or only remove energetic materials—are reviewed with respect to their more limited capabilities while recognizing that a combination of these technologies in a treatment train would be needed to demilitarize whole munitions.

Thus, the distinction between whole and partial munitions processing depends on the size and complexity of the munition involved. The same contained detonation chamber that can entirely demilitarize a small munition may require a step to modify the energetics e. These treatment processes contain scrubbers, cyclones, baghouses, filters, and other components as needed. They were evaluated as part of the technologies with which they are associated. These are noted as part of the technology description. Several of the technologies have the capability to produce materials that can be reclaimed, recycled, or reused R3. Technologies that have R3 capabilities include the SDC, Decineration, deactivation furnaces, autoclave meltout and water washout to recover energetics for alternative uses, and the metal parts flashing furnace to decontaminate metal parts.

Where an R3 capability exists, it is noted as part of the technology description. The technology reviews include a basic description of the technology and, where the information is available, the following: A summary of throughput capacity, taking into account physical feed size limitations, explosion containment limitations imposed by U. It can also refer to the explosive content of the munition; in terms of its net explosive weight NEW , measured in TNT-equivalent pounds of explosive. The quality and detail of the information the committee received in each of these areas varied widely, from in-depth technical information to cursory replies. In some instances, the committee did not receive any information in one or more of the areas for a given technology.

This was either because it was nonpublic information e. Additional information, where available, includes the following: Technical maturity of the technology; Permitting status, including throughput and other limitations imposed by permits; Ability of the technology to process a variety of munitions, defined by the Army as the omnivorous capability; 2 Where capabilities for existing units are limited, the potential to modify the technology to expand its capabilities; The potential for monitoring emissions and for recycling effluents for further treatment; and Resource requirements to operate the technology. These include but may not be limited to munitions disassembly, size reduction to reduce the physical size and net explosive weight of the munitions, and removal of energetic components from the munition.

Commonly used processing steps that are used by PD Demil and its contractors are described below. Disassembly and Size Reduction This step consists of separating munitions components and size-reducing the components to achieve the maximum net explosive weight NEW limit requirements of the treatment technology being used and to expose the energetics within the munition to enable the munition components to be further treated.

Processes currently in use are Manual and automated disassembly U. Manual and Automated Disassembly Some munitions can be disassembled prior to removal and treatment of explosive components, either manually or robotically. Manual disassembly is slow and presents risks to workers, as they must handle the munitions. Automated disassembly with less worker exposure to the munitions is carried out on processing lines at some contractor facilities where complex munitions—for example, cluster bomb units—are taken apart to expose the submunitions within and where the submunitions are also disassembled to expose explosive materials such as shaped charges. These operations incur periodic accidental detonations, and, when these occur, replacement equipment is needed. For example, the unintended detonation rates during the demilitarization of grenades from cluster munitions at a General Dynamics facility in Missouri has been 1 in This allows access to the energetics so they can be treated by thermal destruction.

Cryofracture by itself does not destroy energetics. The munitions debris is then fed to a thermal treatment process such as the APE rotary kiln incinerator for energetics destruction. Cryofracture can be used on munitions that require a size reduction processing step and are difficult or costly to disassemble or will cause damage if they detonate during thermal treatment. It has been successfully used on munitions such as 8 inch, mm, and mm projectiles; M23 landmines; M55 rocket motors; 4. Although the U. An advantage of cryofracture is that it allows access to energetics in a munition more quickly than using other methods such as a band saw or a water jet.

Also, incomplete crushing occasionally occurs, with resulting incomplete deactivation of munitions e. When this occurs, energetic-contaminated materials are processed through the kiln a second time. For example, Artillery Delivered Antipersonnel mines can be processed at a rate of 6 mines per minute, 7 for Rockeye bomblets the rate is 7 munitions per minute, and for M42 submunitions the process rate is 42 items per minute. Permitting constraints regarding emissions and throughputs for the APE govern the process. Personnel Safety Cryofracture is generally conducted remotely by robots behind blast walls to avoid human exposure to safety hazards. If a detonation were to occur while a munition is being processed in the press, the currently used system can withstand a detonation of up to 5 lb NEW. Safety considerations make it most suitable for munitions without a detonator train near the stress points exerted by the cryofracture tooling.

Explosive Hazard Report Powerpoint
Cost Information was not made available to the committee. Waterjet and Slurry Jet Cutting Waterjets are used both to access munitions by cutting the munitions open to expose the energetics inside and to remove energetics washout. Waterjets use a high-velocity stream of fluid forced through an orifice to form a jet. The fluid is typically water, but other fluids can be used. Abrasives can be added to the stream in the form of a premix slurry or by entrainment at the nozzle to increase the cutting action. While the water can often be recovered and reused, eventually it must be treated as explosives-contaminated wastewater pink water and undergo proper treatment before disposal. Waterjets have been used since the s to wash out high explosives HE from munitions. High-pressure waterjets with added abrasives have been used since to cut HE munitions. Low-pressure jets were used in the s for the U.
