INTERVENTION SYSTEM ON THE PRIMARY PIPES AND THE WATER BOX OF A NUCLEAR POWER STATION GENERATOR.

摘要

THE INVENTION REFERS TO A SYSTEM OF INTERVENTION IN THE WATER TANK OF A STEAM GENERATOR OF A NUCLEAR POWER PLANT. THE SYSTEM CONSISTS OF A FIRST ELEMENT (1) WITH A SENSITIVELY LONG FORM AND THAT FORMS A FIRST ARM OF THE SYSTEM, AND OF A SECOND ELEMENT (2) THAT IS ALSO LONG IN FORM. THIS IS ARTICULATED AT ONE OF ITS ENDS TO ONE OF THE FIRST ELEMENT (1). THE FIRST AND SECOND ARM ASSEMBLY (2) IS SUSCEPTIBLE TO ENTER THE TANK (BAE) OF THE STEAM GENERATOR THROUGH AN ACCESS HOLE (TH). THE SECOND ELEMENT (2) CAN BE PLACED UNFOLDED IN RELATION TO THE FIRST (1). A VEHICLE (3) THAT IS MOVED MOUNTED IN RELATION TO THE SECOND ARM (2), ALLOWS TO EXPLORE AND GUARANTEE THE DECONTAMINATION OF THE DIFFERENT PARTS OF THE TANK (BAE) OF THE STEAM GENERATOR. AN INTERVENTION ELEMENT, FOR EXAMPLE OF DECONTAMINATION (30), IS TRANSPORTED BY THE VEHICLE (3) AND CAN REACH DIFFERENT AREAS OF THE INTERNAL SURFACE OF THE GENERATOR. THERE ARE REMOTE CONTROL ELEMENTS (6) OF THE VEHICLE (3) AND INTERVENTION ELEMENTS (30).
