The invention relates to a treatment device and method for a spent fuel assembly. The treatment device for the spent fuel assembly comprises a cleaning tank provided with an injection port, wherein the injection port is used for injecting flushing fluid to a preset height, and the flushing fluid comprises organic water-soluble substances; a heater mounted on the cleaning tank and used for heating the flushing fluid in the cleaning tank; a first pipeline, a second pipeline and a third pipeline which are sequentially in communication, wherein one end of the first pipeline communicates with one end close to the bottom of the cleaning tank, and one end of the third pipeline communicates with one end close to the top of the cleaning tank; and a centrifugal pump arranged on one of the pipelines, wherein the centrifugal pump is used for driving the heated flushing fluid to flow in a loop formed by the first pipeline, the second pipeline, the third pipeline and the cleaning tank, so that the lead-bismuth coolant on the spent fuel assembly soaked in the flushing fluid is stripped by the flowing flushing fluid. The treatment device for the spent fuel assembly can ensure the storage safety of the spent fuel assembly in a storage water tank.
Description
technical field [0001] The present application relates to the technical field of lead-based fast reactors, in particular to a processing equipment and method for spent fuel assemblies. Background technique [0002] With the development of lead-based fast reactor technology, how to ensure the storage safety of spent fuel assemblies is becoming more and more important. The spent fuel assembly unloaded from the reactor, due to its high radioactive activity and decay heat, must be stored and cooled in the storage pool close to the reactor for at least several months, so that the radioactivity and decay heat of the spent fuel assembly can be reduced for the next step. Phase handling, transport and handling. [0003] At present, after the spent fuel assemblies are unloaded from the reactor, the spent fuel assemblies are directly placed in the storage pool for storage. [0004] However, directly placing the spent fuel assemblies in the storage pool after unloading the spent fuel ...
