DGP's senior management was assembled to generate a solution. The New Safe Confinement was assembled in the following steps: This process of assembly was deemed advantageous because it took advantage of the designed mobility of the structure to maximize the distance between workers and the reactor building, thereby minimizing their exposure to radiation. Once decontaminated to the maximum extent practical, pieces will be further fragmented for eventual disposal.
