Described is a method of removing explosive agents from the interior of explosive agent filled bodies such as munitions shells. A rotating nozzle is inserted into an opening cut into the shell. Ultra-high pressure fluidjets (i.e. above 40,000 psi) are projected from orifices in the nozzle onto the explosive agent in the shell. Explosive agent and explosive agent laden fluid is contained and carried away from the shell for recycle or disposal.

[ We claim:] [12.] A method for the removal of explosive agent from explosive agent filled bodies comprising:(a) supplying fluid from a fluid supply means;(b) pressurizing the fluid to ultra-high pressures using a pressurizing means which pressurizes the fluid to more than about 40,000 psi;(c) chill

[ We claim:] [12.] A method for the removal of explosive agent from explosive agent filled bodies comprising:(a) supplying fluid from a fluid supply means;(b) pressurizing the fluid to ultra-high pressures using a pressurizing means which pressurizes the fluid to more than about 40,000 psi;(c) chilling the fluid by use of a chilling means to a temperature at least below the melting point of the explosive agent to be removed;(d) inserting a directing means into the explosive agent filled body along a rotational axis of symmetry of the body;(e) rotating either the directing means or the body about the rotational axis of symmetry of the body along which the directing means was inserted;(f) projecting the fluid onto the explosive agent contained in the explosive agent filled body using the directing means whereby the explosive agent is removed from the interior of the body;the directing means having a hollow lance, a nozzle and a plurality of orifices through which the fluid is projected, each of the plurality of orifices having a diameter in the range of about 0.001" to about 0.020"; and(g) stripping the directing means of removed explosive agent accumulated thereon using a stripper means in which a plurality of washer nozzles project a fluid onto the outer surface of the directing means at a pressure high enough so as to remove accumulated explosive agent from the outer surface of the directing means.
