Method for decommissioning nuclear facility using bio-protective concrete
A recently granted patent (Publication Number: US12002594B2) outlines a method for decommissioning a nuclear facility, specifically focusing on the process involving a nuclear reactor pressure vessel. The method involves floating the vessel above a cavity in bio-protective concrete, rotating it so that the upper portion is closer to the concrete, and then mounting and cutting the vessel. The process utilizes cranes for floating, rotating, and positioning the vessel, with specific steps outlined for each stage of the decommissioning process.
Furthermore, the patent details additional steps for facilities with pipes directly connected to the pressure vessel, including expanding the concrete cavity's inner wall and separating the pipes from the vessel. The method also specifies a 180-degree rotation of the vessel during the decommissioning process. This innovative approach to decommissioning nuclear facilities aims to streamline the process while ensuring safety and efficiency in handling the reactor pressure vessel. The use of cranes and bio-protective concrete showcases a systematic and structured approach to dismantling nuclear facilities, emphasizing the importance of precision and careful handling in such critical operations.
