Abstract
An apparatus and a method for inspecting an outer jacket of a core containment in the region of a heat shield surrounding the core containment, include a plate mounted rotatably on a bottom of a storage basin. The core containment is deposited on the bottom. A mast is deposited on the bottom next to the core containment. A vertical carriage is disposed on the mast for movement in the longitudinal direction of the mast. An outrigger which is disposed on the vertical carriage can be introduced into a region between the outer jacket of the core containment and a heat shield and has a free end which carries an inspection device.
Claims7
In an assembly having a core containment with an outer jacket, a heat shield surrounding the core containment and defining a region between the core containment and the heat shield, and a storage basin having a bottom, an apparatus for inspecting the outer jacket in the vicinity of the heat shield, the apparatus comprising:
- a) a plate for receiving the core containment, said plate mounted for rotation about an axis of rotation on the bottom of the storage basin;
- b) a mast disposed on the bottom and having a longitudinal direction extending parallel to the axis of rotation of said plate;
- c) a vertical carriage mounted on said mast for movement in the longitudinal direction of said mast;
- d) an outrigger disposed on said vertical carriage for introducing said outrigger into the region between the outer jacket of the core containment and the heat shield, said outrigger having a free end;
- and
- e) an inspection device carried on said free end of said outrigger.
A method for inspecting an outer jacket of a core containment in the vicinity of a heat shield surrounding the core containment, which comprises:
- a) mounting a plate on a bottom of a storage basin for rotation of the plate about an axis of rotation;
- b) depositing a core containment with an outer jacket onto the plate;
- c) depositing a mast having a longitudinal direction on the bottom next to the core containment with the longitudinal direction of the mast extending parallel to the axis of rotation of the plate;
- d) placing a vertical carriage on the mast for movement in longitudinal direction of the mast;
- e) placing an outrigger with a free end, on the vertical carriage;
- f) carrying an inspection device at the free end of the outrigger;
- and
- g) introducing the outrigger into a region between the outer jacket of the core containment and a heat shield surrounding the core containment.
