HRT-CP: Results of Solids Dissolution Tests

Description: A dissolution cycle in the chemical plant consists of refluxing with 10.8 M H2SO4 for 4 hours followed by refluxing for a like period with 4 M acid. In each of 3 tests in which 370 gram batches of simulated corrosion product solids were subjected to two dissolution cycles using 820 excess acid more than 99.6 of the solid material was dissolved (based on the amount of undissolved material collected). In another test using one dissolution cycle and 820 excess acid 99.5 of the solids material was … more

Progress Report, Subcontract No. 501-Under W7405-eng-26

Description: This is a progress report for the period of April 1, 1953 to June 30, 1953. Results reported by the Naval Research Laboratory indicate that the pressures above are less than this laboratory reported previously and that equilibrium, as measured by a constant gas pressure, may be reached in a relatively short time.

Suggested Major Equipment for NPR Water Quality Control Labs

Description: Two water quality control labs are being provided for the the NPR. One, a "cold" lab, is located in the183 Building adjacent to the control room. Its primary purpose is to provide facilities for quality control of the output of the filter plant and the demineralizer plant. The other, a "hot" lab, is located in the 190 Building. Its primary purpose is to provide facilities for the quality control of the primary and secondary coolants, and the moderator coolant.

Project C-431-A Production Facility design computations on outfall structure 1900-C

Description: Project C-431-A includes the design of the C Water Plant outfall structure. This report documents design assumptions and the design of the spillway, outfall sewers, spillway chute, trash racks, walkways, stop log and trash rack slots, main sewer, and retention sewers. The spillway capacity is to be 268,000 gpm with a crest elevation at 429.0. This flow capacity is composed of flow from the 105-C Retention Basin (80,000 gpm), 105-B Retention Basin (45,000 gpm), and the 190-C Area main sewer (143… more

Effect of pH and Concentration of Ammonium Persulfate on Colorimetric Determination of Nickel by Dimethylglyoxime Method

Description: The following report records the study of the optimum pH of the method of the colorimetric dimethylglyoxime for nickel before the addition of oxidant and the concentration of ammonium persulfate needed to insure complete oxidation to higher nickel valence states and thus prevent precipitation of less soluble nickelous salt that was made. Results of this study is presented in Table 1.
