Argonne to investigate Pu chemistry to aid Hanford cleanup
Researchers at the Department of Energy’s Argonne National Laboratory are investigating the details of plutonium chemistry with the goal of aiding the cleanup of the Hanford Site in Washington state. For more than 40 years, reactors located at Hanford produced plutonium for America’s defense program, resulting in millions of gallons of liquid radioactive and chemical waste.

The feasibility of spatial and temporal power density flattening in fusion-fission hybrid reactors was investigated by varying the concentration of 239Pu within a set of zones in the fission region and by examining two different fuel management schemes. Blanket designs with no 239Pu typically had a spatial maximum-to-average power density ratio of ∼2.5, but this value was reduced to between 1.26 and 1.67, depending on the design and fuel management scheme selected. Unfortunately, however, significant impact occurs only with relatively high fissile concentrations, with the outer zones approaching equilibrium values. Thus, either an impractically large fissile inventory for startup or long operating histories would be required.
