Fundamental Understanding of Nucleation Processes to Assess Solution Stability and Phase Growth and Genesis

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Gregg Lumetta

Many activities in the nuclear industry are areas of concern for public safety. The leakage of nuclear waste from Hanford storage tanks poses a threat to public health, and the retrieval and…

An In-situ Investigation of a-AlOOH Dissolution under High pH Conditions

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Edgar Buck

The dissolution and precipitation of gibbsite [a-Al(OH)3] and boehmite [a-AlOOH] is of prime importance to the final disposition of high-level nuclear waste (HLW) stored at the Hanford Site. The high…
