| Mark-22 irradiated fuel assemblies | K-, P-Reactor Disassembly Basins |
| Other aluminum-clad fuel and targets - About 650 aluminum-clad fuel and targets containing thorium to produce uranium-233, cobalt used as part of the reactor power control because it is a neutron absorber, thulium, monitor pins and slugs. The reactor basin water chemistry is being improved to minimize the corrosion of the targets.c | |

a. RBOF = Receiving Basin for Offsite Fuels.
b.
SRTC = Savannah River Technology Center.
c. The reactor basin
water chemistry is being improved to minimize the corrosion of the targets. The
water is deionized to lower its conductivity, which reduces general aluminum
cladding corrosion and the galvanic couple between racks and target and fuel
assemblies. Stored materials are monitored for evidence of corrosion and other
failure and, as needed, repackaged to reduce sludge formation on basin bottom.
