Report (Shipment #11) discusses mechanical changes to the processing operation such as glass equipment setup, ventilating system, Cell B sump jets, and Cell A duct jet. Dissolver operations were described as 831 slugs were pushed and charged to the dissolver for Run #3 from 7/17/45 to 7/17/45. Extraactions, metathesis, and Cell B operation are discussed, along with analyses of results after the completed run shown in table form. Contamination is discussed. The vessel ventilating system become hot and the radiation in the fan house reaching several r/hour. However, lead shielding on the small off-gas line prevented above-tolerance level readings in the adjacent working areas; and activity next to the cell remained at about 30 mr/hour. An evacuation of the building occurred, similar to one during the previous run, when active waste being discharged from B3 to A9 backed out the steam line during cleanup to the B1-A9 jet. Slight personnel exposure occurred during sampling with the B3 blister due to the fact that increased shielding took up more space, thus decreasing room to move in the blister and causing a greater time required for sampling which resulted in over exposure. The design will be changed. Mechanical problems with sump overflow in Cell A are also discussed.
