Removal of Shippingport Station primary system components and piping

The primary system components within this workscope consist of the stainless steel reactor coolant piping, check valves, reactor coolant pumps, steam generators, and reactor purification demineralizers and coolers. The four reactor coolant pumps, the four check valves, and several sections of reactor coolant piping were removed and shipped to a laboratory for metallographic examination. This paper describes the work performed, the heavy rigging preparations and procedures, the cutting tools used, component draining/capping techniques to prevent spills, contamination containment, airborne control techniques, and lessons learned during the removal of these primary system components. Summaries of crew size and composition, labor hours, duration hours and radiation exposure to workers are provided and discussed briefly. 6 figs
