Comosion of aluminum-clad spent nuclear fuel being stored in the light-water fdled basins at the Savannah River Site was first observed in mid-1991. A corrosion surveillance program was initiated at that time in the P, K, and L-Reactor basins and in the Receiving Basin for Offsite Fuels (RBOF). This program verified the aggressive nature of the pitting corrosion and provided recommendations for changes in basin operations to permit extended longer term interim storage. The changes were implemented during 1994-1996 and have resulted in significantly improved basin water quality with conductivity in the...
