摘要： A method for harvesting activated irradiation targets from an instrumentation tube system of a nuclear reactor comprises: Coupling the instrumentation tube system to a discharge tube having an apex, exit port and lock element between the apex and exit port; Passing the activated irradiation targets from the instrumentation tube system into the discharge tube and blocking movement of said targets out of the discharge tube using the lock element; Separating a predefined quantity of the targets from another quantity of targets in the discharge tube by passing the predefined quantity of targets over the apex, retaining the remainder in the discharge tube by means of the apex; Coupling the exit port to a storage container and releasing the lock element to pass via gravity the predefined quantity of targets into the storage container. Systems for generating radionuclides and harvesting activated irradiation targets adapted to the above method are also provided.
