Metal components of the separated rocket motor2 can be recovered for recycling after they have been mutilated to preclude restoration for further use in a rocket motor (DoD, 2011)

The technologies can be divided into thermal and chemical. Thermal technologies for separated rocket motor demilitarization and disposal include open detonation, buried detonation, contained detonation, open burn, open static firing, contained combustion, contained static firing, confined combustion, and incineration.

The contained technologies would need to be permitted through RCRA Subpart X and would have to meet release limits agreed on with the Kentucky Department for Environmental Protection. Open Thermal Technologies Open Detonation Open detonation involves placing whole or broken-down rocket motors in a pile with a booster explosive.

From page 24... ...
Others conduct open burning of whole rocket motors by cracking the motor case open with a shaped charge that also initiates propellant combustion. Gaseous and particulate emissions from the burning propellant are not treated further and are released into the local atmosphere.
|
From page 25... ...
Open burning of rocket motors requires the removal of the propellant from the case to prevent propulsive events, and this increases the handling of the items being disposed of. Finally, ash from the process is probably laden with heavy metals from the propellant formulation and must be tested to determine whether it must be handled as a hazardous waste.

From page 26... ...
However, as with contained detonation, emissions of toxic metals, semivolatile compounds, and nonvolatile compounds from the ordnance will contaminate the interior of the chamber and pose a risk to personnel safety, and lead compounds would be a contaminant from the combustion of M28 propellant. In addition, residues will require assessment for treatment as hazardous waste, and metal scrap must be managed as MPPEH.

From page 27... ...
However, the motor residues would need to be removed after each treatment event, and this will limit process throughput. As with contained detonation and contained combustion, emissions of toxic metals, semivolatile compounds, and nonvolatile compounds from the ordnance will contaminate the interior of the chamber and pose a risk to personnel safety.

From page 28... ...
Four explosive destruction technologies (EDTs) have been and are being evaluated for disposal of the rocket motors separated from the M55 rockets stored at BGAD and for other uses in chemical demilitarization and disposal processes.3 These EDTs are a subset of the conventional demilitarization and disposal technologies described in this chapter.

From page 29... ...
As constructed, these are contained detonation chambers. CH2M HILL has proposed using a modified version of the D-100 chamber currently installed at BGAD as a contained static-firing chamber in which separated rocket motors would be fired in their design mode into a containment vessel before treatment of the exhaust products.

that a separated rocket motor processing throughput rate of 167 motors per day will be needed to keep pace with M55 rocket processing at BGCAPP. Open thermal technologies result in atmospheric releases of respirable lead dust from the M28 propellant.

The carcass will require assessment as hazardous waste and MPPEH.a Contained The rocket motor is secured and Handling is minimized. A nontrivial fraction of lead in the propellant static firing fired into a containment vessel in remains in the carcass after treatment in the form Combustion occurs at high pressure, and this its design mode.
