Title: Integrated approach to trailer design for spent fuel casks

Abstract

General Atomics (GA) is developing the GA-4 and GA-9 spent fuel transportation systems. The scope of our contract includes spent fuel casks, legal weight trailers, and ancillary equipment. Recent structural failures of spent fuel trailers have focused attention on trailer design. As a major element of spent fuel transportation systems, the concerns address the adequacy of trailer performance requirements, structural design and analysis, and in-service inspection and maintenance procedures. In response to these concerns, GA has applied an integrated approach to the design of the GA-4 and GA-9 transportation systems. The objectives are to design reliable, high-integrity trailers and to demonstrate their performance by test. Once the design is complete, a prototype trailer will be fabricated and a performance test program conducted in accordance with a comprehensive test program. GA`s trailer test program will include both design and operations elements, and will be used to optimize the operations and maintenance plan. The results of this program will provide positive public and regulatory perception of trailer durability and will support the development of industry standards for both legal weight and overweight trailers for spent fuel applications. 2 figs.

  • Recent ductile cast iron (DCI) research work, as applied to transport casks, in the United States has focused on developing a design methodology which could be used as acceptance criteria for DCI casks. Sandia National Laboratories has concentrated on advancing the linear elastic fracture mechanics design approach to cask design. The approach allows for the design of transport casks fabricated out of ferritic materials (such as DCI) which undergo a brittle/ductile failure mode transition. The Sandia program encompasses material characterization, finite element structural analysis, nondestructive examination evaluation and drop test verification. Recent results of the program and near-term efforts aremore » described. 6 refs., 5 figs.« less
  • A PRA approach which uses comparison of alternative safety systems is proposed. The method assumes a linear risk model, and uses a selected probability function to compare the system of interest and an acceptable reference system. Features of the reference system may be varied to assess effects on system safety. The method is demonstrated by addressing effects of burnup credit on criticality control, an issue of current interest in the area of transport of radioactive materials. The example illustrates how the method measure effects of system changes, and how compensatory features can be introduced and assessed in terms of riskmore » or reliability control. 6 refs., 7 figs.« less
