Production of I sup 131

Description: We have reviewed the problem of recovering I{sup 131} from the Separations Process and conclude that recovery is entirely feasible. This report contains recommendations for I{sup 131} recovery offered for consideration and are based on a technical study.

Production test 105-2-P (Supplement A) - Activity of pile discharge water (Activation of manganese and iron)

Description: This report discusses the Production Test 105-2-P (Supplement A) -- Activity of Pile Discharge Water. Previous studies of pile discharge water have shown that one of two processes is responsible for the large but variable amount of Mn{sup 56} activity present in the water. One process is the production of Mn{sup 56} by the reaction Mn{sup 55} on manganese impurity in the water. The amount of such impurity has been shown to be too small to produce the observed amount of Mn{sup 56} unless the mea… more

Final report on Production Test 105-8-P -- Film formation

Description: Tests made prior to beginning operation of the 100 Areas showed that the cooling water had a tendency to deposit a film upon the slug and tubs surfaces. This film would manifest itself as an increase in the pressure drop through the tubes and its most serious affect would be the resultant decrease in the slug to water host transfer coefficient which would increase the slug surface temperature, causing greatly accelerated corrosion rates. It was thus proposed to study film formation an a product… more

Columbia River temperature study at 100-F Area

Description: In August 1946 it was discovered that two effluent lines near the Columbia River at Hanford were damaged. The upstream effluent line has broken off 37 fact from the shoreline and the downstream effluent line had been bent and partly broken seventeen feet from shoreline and has swung downstream to a point about 50 feet from shorelines. This study was made to determine how fast and in what fashion the temperature of the effluent water is dissipated in the Columbia River under the present conditio… more

100 Areas, January 1 through January 7, 1946

Description: During this period the B Pile operated at its assigned power level of 25 MW below rated level, except for 10 hours on January 5. The operating level of the D Pile remained at 25 MW below rating. The rate gain in excess reactivity during equilibrium operation has been about 1.8 inhours/day. On January 1, the power level of the F Pile was dropped to 25 MW below rating from its previous rated level. Rod A was in a favorable position to make a determination of the reactivity coefficients at the tim… more

Columbia River temperature survey at Hanford Engineer Works. Final report

Description: It was agreed during a meeting on July 10, 1945, investigation should be made to determine how fast and in what fashion the temperature of the effluent water from the 100 Areas is dissipated in the Columbia River. A preliminary report on these investigation was issued March 1, 1946: it discussed the testing techniques developed and the results of a survey made at the 100-B Area. Following a review of the data and tentative conclusions resented therein, it was agreed to extend the survey using s… more

300 Area, January 22--January 28

Description: Progress is reported on the topics of extrusion and canning. The information on canning is broken down into: Production test 313-74-M, studies of aluminium cans, selection of surface rejection standards, thorium, and the effect of high and low tin in bronze on tin carry-over to canning bath.

100 Areas, July 23 through July 29. For technical progress letter number 108

Description: The weekly progress for D and F piles is given. Status of the test to determine the cause of white deposits on the horizontal control rods of the F pile is given. Also discussed are studies of process water control and pressure drop, corrosion, and graphite expansion. Test results indicate that graphite expansion has not seriously limited discharge of process tubes.

Production test-105-55-P -- Reactivity of the B Pile under shutdown conditions. Interim report

Description: At the shutdown of the B Pile, 269 active tubes were discharged and ten poison columns were charged. As a result, the pile was let considerably below critical. The present test described in this report was set up to develop methods of detecting possible changes in reactivity by periodic measurements of neutron flux in the shutdown pile. The irradiation of indium foils in an empty process tube was found to provide a satisfactory method of monitoring the shutdown pile, and was sensitive than the … more
