    Abstract: Method for decommissioning a body containing explosive material includes opening the body containing explosive material in a secured and/or currentless state, and cutting individual bodies along a cutting plane into at least two parts in a liquid by one or more cutting processes to expose the main charge carriers intact in the respective individual bodies for removal without destruction. Method further includes removing main charge carrier essentially intact while still in the liquid from the individual bodies, and transferring the main charge carrier to a container, structured and arranged to store each individual main charge carrier free from contact with other main charge carriers, and which includes a material that is absorbent for liquids. Method further includes feeding the container with the main charge carriers to an incineration process and grinding all of the other parts of the individual bodies in a grinding process to produce ground material.
