Abstract: A method of operating a basic industrial plant complex efficiently utilizing energy, products, byproducts, and waste materials between the basic industrial plants as a whole to totally improve energy efficiency and contribute to energy saving. The basic industrial plant complex comprises basic industrial plants including an oil refining plant, an oil-fired power plant, a cement plant, a steelmaking plant constructed so as to be in close proximity to or adjacent to each other. The basic industrial plants are combined through a transporter for partially or completely supplying product, byproduct or waste material from a plant in the complex as a fuel, power source, and/or raw material to products for another plant in the complex.

Abstract: Disclosed is an improved process for cement solidification treatment for disposition of spent ion exchange resins exhausted from nuclear power plants.The wet resin particles are centrifuged to remove free water therefrom and subjected to the pre-treatment of coating with a small amount of cement powder, and then, cement powder and water is added to the resin particles and the mixture is kneaded to form cement paste, which is cast in to a vessel for solidification.The cast product contains much more resin particles and has improved water-resistability.
