Abstract
A method for disposing of a component located in a reactor pressure vessel of a nuclear reactor plant. The component is, in particular, a lower core structure of a pressurized water reactor plant. An upper part of a container provided for further transport is disposed above an opened and flooded reactor pressure vessel. The upper part is provided with a lower orifice. The component is raised through the orifice into the upper part of the container and is subsequently transported to an upwardly open lower part of the container. The upper part is assembled together with the lower part to form the container, so that the component is enclosed and shielded in the container.
Claims5
A method for disposing of a component located in a reactor pressure vessel of a nuclear reactor plant, the method which comprises:
- a) providing a container intended for further transport having an upper part with a lower orifice and an interior at least partly below a water level of a flooded reactor well, and placing the upper part above an opened reactor pressure vessel disposed in the flooded reactor well;
- b) picking up the component with a lifting appliance and raising the component through the lower orifice into the upper part of the container;
- c) placing an upwardly open lower part of the container next to the reactor pressure vessel in the flooded reactor well, transporting the component to the lower part of the container, and placing the component onto the lower part of the container;
- and
- d) assembling the upper part together with the lower part to form the container with the component enclosed in the container.
