Abstract: A method includes a first phase of characterizing waste of a plant and a second phase of selecting at least one system for treatment and determination of associated predicted streams of waste. The first phase includes a step of physical characterization and radiological characterization of each area, a step of physical characterization and radiological characterization of all the items of equipment present in the areas as a function of the step of characterization of the areas, and a step of compiling the physical and radiological characteristics of the items of equipment in which a description of a waste item to be produced is associated with the physical and radiological characteristics of each item of equipment. The second phase makes the selection of at least one system for the treatment and the determination of the associated predicted streams as a function of the descriptions of the waste to be produced and of the physical and radiological characteristics of the areas.

Abstract: A method for evaluating specific data in relation to the cleaning up/dismantling of a facility comprising at least one room. This method includes the following steps: an inventory of the facility is drawn up room by room, assimilating each room with a standard cell which brings into play at least one task to obtain first data, a set of tasks is associated with a standard scenario, each task is associated with at least one ratio in order to modify the first data so as to obtain second data, specific data is determined by evaluating this second data taking into consideration services provided in relation to manpower and general elements.
