“…9 For a tank diameter of 85 ft and a U 0 D of 13.6ft 2 /s, the calculated mixing time is 1.1 hours. The mixing time is increased 4X to account for uncertainty, producing a final mixing time of 4.4 hours.…”

“…To determine the pump requirements to blend miscible liquids in Tank 50H, the author reviewed the pilot-scale blending work performed for the Salt Disposition Integration Project (SDIP) 9 and applied the results to Tank 50H to determine the number, size, and operating parameters needed to blend the tank contents.…”

“…As a follow on to this work and to help Savannah River Remediation (SRR) determine the necessary pump for blending miscible liquids (i.e., salt solution) in the Salt Disposition Integration Project (SDIP) Blend and Feed tanks, SRNL conducted pilot-scale liquid blending tests 9 in a nominal 1/10 th scale type IIIA waste tank. a The pilot-scale testing showed that a type IIIA waste tank (e.g., Tank 50H) could be blended with a single standard non-rotating pump with two opposing nozzles provided that the nozzles had a U 0 D greater than 8.8 ft 2 /s.…”

“…Since a standard slurry pump has a nozzle diameter of 1.5 inches and a maximum flow rate of 600 gpm a Actual scale was 1/10.85 by linear dimension -4 -per nozzle (maximum discharge velocity of 109 ft/s and maximum U 0 D of 13.6 ft 2 /s), a single standard slurry pump will be able to blend miscible liquids (i.e., salt solution) in Tank 50H. 13 In the pilot-scale tests 9 , the mixer pump did not rotate. However, a rotating mixer pump will improve the mixing and reduce the blend time for miscible liquids.…”

“…The mixing time is increased 4X to account for uncertainty, producing a final mixing time of 4.4 hours. 9 Therefore, a single rotating standard slurry pump (with a 13.6 ft 2 /s U 0 D) will be able to blend miscible liquids (i.e., salt solution) in Tank 50H within 4.4 hours.…”
