Hanford begins removing waste from 24th single-shell tank
The Department of Energy’s Office of Environmental Management said crews at the Hanford Site near Richland, Wash., have started retrieving radioactive waste from Tank A-106, a 1-million-gallon underground storage tank built in the 1950s.
Tank A-106 will be the 24th single-shell tank that crews have cleaned out at Hanford, which is home to 177 underground waste storage tanks: 149 single-shell tanks and 28 double-shell tanks. Ranging from 55,000 gallons to more than 1 million gallons in capacity, the tanks hold around 56 million gallons of chemical and radioactive waste resulting from plutonium production at the site.

Non-axisymmetry of the plasmas as well as fluctuations including turbulence causes the radial transport in a mirror configuration. The azimuthal distribution and fluctuations of floating potentials on a segmented limiter in the central cell are measured to evaluate the degree of the axisymmetry of plasmas.
