Abstract
A reactor vessel stud cleaning machine for cleaning reactor studs. The stud is supported horizontally by a pair of roller carriage assemblies inside of a closed chamber. At least one roller carriage assembly has rollers driven by a stud drive motor which cause the stud to rotate. As the stud rotates, a spray nozzle traverses the length of the stud spraying a mixture of high pressure water and abrasive onto the stud. The spent water and abrasive is drained from the enclosure and pumped through a separator funnel and filter bank to remove solids. The filtered water is returned to a supply tank for reuse. The stud rotation speed and spray nozzle traverse speed the variable as in the water pressure and rate of abrasive injection.
