AI Technical Summary
Existing methods for treating waste inside a nuclear reactor pressure vessel during decommissioning are inefficient, requiring separate equipment and processes that complicate the separation of the reactor vessel from bio-protective concrete.
An apparatus comprising a suction unit with flexible inserts, including a camera, manipulator, chemical injector, stirrer, ultrasonic generator, and air injector, which is inserted through through-pipes in the reactor vessel to suck, treat, and collect waste, without the need for additional structural modifications.
The apparatus enables efficient treatment of waste inside the nuclear reactor pressure vessel by physically crushing, chemically dissolving, and stirring solids within the waste, allowing for easy collection and processing, thereby simplifying the decommissioning process.
