Transporting the damaged core from the Unit 2 reactor of Three Mile Island (TMI-2) Nuclear Power Station near Harrisburg, PA, to the Idaho National Engineering Laboratory (INEL) near Idaho Falls, ID, has required careful attention to safety of the public. As part of that attention, specially designed casks and railcars, called the NuPac 125-B Rail Cask system, were built to make those shipments. More than 30 rail cask loads of core debris from TMI-2 have been transported across country to INEL without incident resulting from performance of the rail cask or railcar. A contributing factor for this safety record is the comprehensive inspection and maintenance program developed for both the rail casks and railcars. This paper describes the NuPac 125-B rail cask and railcar, and identifies the regulatory requirements governing inspections, preventative maintenance, and quality assurance records. This paper also discusses inspection and maintenance experiences that have resulted in hardware and procedural enhancements. 7 refs., 3 figs., 4 tabs. (ERA citation 14:012925)
