Apparatus for the ultrasonic examination of shroud hold down bolts

A process of testing hold down bolts depending from the sides of a steam separator within a nuclear reactor is described the process comprising the steps of: maintaining the steam separator under water; moving the bolts to unlatch the bolts from brackets on the shroud adjacent the steam separator; providing a shoe having a piezoelectric device mounted to the bottom of the shoe and exposed upwardly; providing a remotely actuated clamp attached to the shoe overlying the piezoelectric device; providing a mount to the shoe for manipulating the shoe underwater in a depending relationship at the bottom end of a pole; providing a pole and attaching the pole to the shoe; manipulating the shoe to the bottom of the bolt; and clamping the shoe to the bolt; and testing the bolt with the piezoelectric device
