“…The purpose of this study is to evaluate the feasibility of HIP processing fuel plates directly, without the use of the stainless steel HIP can. Previous studies (Montalvo et al 2013) have shown promise that properly prepared Al 6061 cladding surfaces can bond successfully (i.e., with observable grain growth across the bond line). Initial analyses have shown the potential for significant labor reductions, while also potentially increasing throughput.…”

SummaryThe purpose of this document is to provide a comprehensive review of the mission of the Fuel Fabrication Capability (FFC) within the Global Threat Reduction Initiative Convert Program, along with research and development (R&D) needs that have been identified as necessary to ensuring mission success. The design and fabrication of successful nuclear fuels must be closely linked endeavors. Therefore, the overriding motivation behind the FFC R&D program described in this plan is to foster closer integration between fuel design and fabrication to reduce programmatic risk by ensuring the following:• The manufacturing process consistently produces fuel with acceptable quality (i.e., meets or exceeds design requirements)• The sensitivity of material properties and characteristics to manufacturing process parameters is clearly understood so adequate process specifications can be defined• Fuel product specifications are realistic and achievable using the selected manufacturing methods• A better linkage between the effect of process parameters on fuel performance, to ensure that changes or variability in manufacturing does not have an adverse effect on irradiation behaviorThese motivating factors are all interrelated, and progress addressing one will aid understanding of the others. The FFC R&D needs fall into two principle categories, 1) baseline process optimization, to refine the existing fabrication technologies, and 2) manufacturing process alternatives, to evaluate new fabrication technologies that could provide improvements in quality, repeatability, or cost. The FFC R&D Plan examines efforts currently under way in regard to coupon, foil, plate, and fuel element manufacturing, and provides recommendations for a number of R&D topics that are of high priority but not currently funded (i.e., knowledge gaps). The plan ties all FFC R&D efforts into a unified vision that supports the overall Convert Program schedule in general, and the fabrication schedule leading up to the MP-1, MP-2, and FSP-1 irradiation experiments specifically.The FFC R&D Plan describes the downselection methodology for optimizing the baseline fabrication process as well as considering alternative manufacturing technologies. The criteria for downselection include the following considerations:• Technical Merit -Does the process produce parts that meet product specification requirements?• Reproducibility -Does the process consistently produce high-quality parts?• Economics -Does the process offer life-cycle (not just capital) cost savings over the baseline process, including considerations of efficient use of uranium feedstock and scrap recycle??• Scaling -Does the process scale to full prototypic part dimensions?• Throughput -Does the process lend itself to high-volume throughput without sacrificing its advantages?• Quality Assurance -Does the process lend itself to implementation in an NQA-1 manufacturing environment?iii • Environment, Safety, and Health -Can the process be implemented effectively in a uranium production facility regulated by ...
