The 10E filter housing at 221-H is leaking and cannot be repaired and will be removed from the system. The need for filtration is a legacy issue related to particulates in the cold chemical feed of nitric acid and has been resolved. In addition, the ferrous sulfamate supply tank 10E will be isolated on third level as the supply to tank 12E is no longer needed for processing.
