That can be adopted by energy block modifications by April 2027, then spent gas rods will cool within the spent gas swimming pools by June 2032 whereas plans are made for decontamination and dismantling of radiological techniques and buildings, in addition to nonradiological buildings, which is able to happen till April 2035.
