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.
