Managing China's spent nuclear fuel: a model framework for interim storage

ABSTRACTChina, as the world leader in constructing new nuclear reactors, has yet to resolve either its short-term spent nuclear fuel (SNF) problems or the challenge of long-term final disposition. While it may be several decades before the fuel disposition question will be resolved, the near-term problem of establishing adequate interim SNF storage is much more acute. The state of nuclear-reactor development in China presents an opportunity to address SNF management issues at an early stage. This article outlines a scenario-based study aiming to inform SNF interim storage policy even while the final disposition solution remains uncertain. We describe a comprehensive model and show results from a crucial subset of issues—the logistics of SNF accumulation, transportation, and storage—and describe simple steps to strengthen the SNF storage system. Finally, we forecast when the current method of SNF disposition could break down and offer recommendations and guidance for further study.
