摘要

Spent nuclear fuels (SNFs) received from reactor sites around the world are being stored in the L-Basin at the Savannah River site (SRS) in Aiken, South Carolina. The predominant fuel types are research reactor fuel with aluminum-alloy cladding and aluminum-based fuel. Other fuel materials include stainless steel and zircaloy cladding with uranium oxide fuel. rnStanding chemistry control and corrosion surveillance programs have been established and upgraded since the early 1990s to minimize corrosion degradation of the aluminum cladding materials, so as to maintain fuel integrity and minimize personnel exposure from radioactivity in the basin water. Recent activities that have been initiated to support additional decades of wet storage include fuel inspection and corrosion testing to evaluate the effects of specific water impurity species on corrosion attack.rnAn overview is given of the activities that have been successful at maintaining spent fuel integrity in wet storage at SRS. Additional topics, including the role of the surface oxide layer in stabilizing aluminum against corrosion during wet storage, and recent research program findings of exfoliation of aluminum during high-heat flux exposure to water that may occur in high power reactor operation, are discussed.
