A sampling system was designed to withdraw slurry from the mixing tank. The slurry simulants for more » the experiments were prepared in-house based on the properties of the DOE sites` typical waste slurries. Most of the research on this project was performed experimentally by using a tank mixing configuration with different rotating impellers. The objective of this work is to determine optimal mixing configurations and operating conditions as well as improved sampling technology for defense waste processing facility (DWPF) waste melter feeds at US Department of Energy (DOE) sites. This report summarizes the methods used and results obtained during the progress of the study of waste slurry mixing and sampling systems during fiscal year 1977 (FY97) at the Hemispheric Center for Environmental Technology (HCET) at Florida International University (FIU). This paper will discuss the history, progress, and future activities that will define and mitigate the mission risk. An evaluation of demonstration program results will identify potential mission improvement considerations that will help ensure successful mission completion. The Hanford mixing and sampling demonstration program will identify DST mixing performance capability, will evaluate representative sampling techniques, and will estimate feed batch consistency. Inconsistent feed to the WTP could cause additional batch-to-batch operational adjustments that reduce operating efficiency and have the potential to increase the overall mission length. It has been demonstrated that homogenous mixing ofHLW sludge in Hanford DSTs is not likely achievable more » with the baseline design thereby causing representative sampling and consistent feed delivery to be more difficult. DOE's River Protection Project (RPP) mission modeling and WTP facility modeling assume that individual 3785 cubic meter (l million gallon) HLW feed tanks are homogenously mixed, representatively sampled, and consistently delivered to the WTP. Do not forget to include the governing wind or seismic shear with the normal operating shear from the agitator to determine the total shear.īy the time you are all done, it may be easier just to supply a shear resisting device rather than fight with the consulting engineer who will keep coming back with various other requests.The ability to effectively mix, sample, certify, and deliver consistent batches of High Level Waste (HLW) feed from the Hanford Double Shell Tanks (DST) to the Waste Treatment and Immobilization Plant (WTP) presents a significant mission risk with potential to impact mission length and the quantity of HLW glass produced. If you look at friction, as was suggested earlier, make sure that you examine a variety of fluid levels including the lowest one that the agitator may be operating at (not necessarily the design level).
#Anchor agitator design calculation code#
I recently finished a project in a high seismic zone where the anchor bolts were not allowed to resist seismic shear (The national seismic design code did not permit) so shear keys were used instead.Obviously bolts were used for the uplift. It may be easier and less expensive than bolts for both the tank manufacturer and owner (assuming that the owner is installing the foundation).
#Anchor agitator design calculation install#
If JStephen's approach doesn't provide the stability you need it may be possible to install a shear key instead of anchor bolts to handle the shear load from the torque.
