Durability of aluminum-clad spent nuclear fuels in wet basin storage
- Westinghouse Savannah River Co., Aiken, SC (United States). Savannah River Technology Center
Large quantities of Defense related spent nuclear fuels are being stored in water basins around the US. Under the non-proliferation policy, there has been no processing since the late 1980`s and these fuels are caught in the pipeline awaiting processing or other disposition. At the Savannah River Site, over 200 metric tons of aluminum clad fuel are being stored in four water filled basins. Some of this fuel has experienced significant pitting corrosion. An intensive effort is underway at SRS to understand the corrosion problems and to improve the basin storage conditions for extended storage requirements. Significant improvements have been accomplished during 1993--1995, but the ultimate solution is to remove the fuel from the basins and to process it to a more stable form using existing and proven technology. Other methods, like dry storage are viable, but they will require development over several years. This paper presents a discussion of the fundamentals of aluminum alloy corrosion as it pertains to the wet storage of spent nuclear fuel. It examines the effects of variables on corrosion in the storage environment and presents the results of corrosion surveillance testing activities at SRS, as well as discussions of fuel storage basins at other production sites of the Department of Energy.
