ABSTRACT:
A support framework has casters which enable it to be moved into position for receiving the studs of nuclear reactor vessels so the studs may be cleaned and inspected. A housing on the framework isolates the stud while it is cleaned to control the radioactive debris removed from the stud surfaces. Brushes for the internal bore and external surface of the stud are mounted for simultaneously moving over the stud surfaces. Eddy current and ultrasonic inspection devices are substituted for the brushes and the internal and external surfaces simultaneously inspected while an encoder connected to both the inspection devices and stud manifest the location of any detected flaws.
