Abstract
An apparatus and a method for inspecting an outer jacket of a core containment in the vicinity of a heat shield surrounding the core containment, include an annular rail to be fixed to the core containment. A carriage is disposed on the annular rail for circumferential movement. A mast is supported on the carriage for axial displacement. A vertical carriage is movable along the mast in the direction of the longitudinal axis of the mast. An outrigger is disposed on the vertical carriage. An inspection device is carried by the free end of the outrigger for movement into a region between the outer jacket and the heat shield.
Claims8
In an assembly having a core containment with an outer jacket and a heat shield surrounding the core containment and defining a region between the core containment and the heat shield, an apparatus for inspecting the outer jacket in the vicinity of the heat shield, the apparatus comprising:
- a) an annular rail to be fixed to the core containment;
- b) a carriage disposed on said annular rail for circumferential movement;
- c) a mast supported on said carriage for axial displacement, said mast having a longitudinal axis;
- d) a vertical carriage to be moved along said mast in the direction of the longitudinal axis of said mast;
- e) an outrigger disposed on said vertical carriage and having a free end;
- and
- f) an inspection device carried by said free end of said outrigger for movement into the region between the outer jacket and the heat shield.
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) securing an annular rail to a core containment having an outer jacket;
- b) mounting a carriage on the annular rail for sliding in a circumferential direction;
- c) supporting a mast on the carriage for axial displacement;
- d) placing a vertical carriage on the mast for movement in the direction of a longitudinal axis of the mast;
- e) placing an outrigger on the vertical carriage;
- f) carrying an inspection device on a free end of the outrigger;
- and
- g) moving the outrigger into a region between the outer jacket of the core containment and a heat shield surrounding the core containment.
