Pacific Northwest Laboratory monthly activities report, January 1968

Description: Analysis of Columbia River temperature trends indicates conformity with those previously reported. Despite unusually high average temperatures, the temperatures of the upper and lower extremes continued to converge on the mean. The construction of the John Day Dam is expected to have little temperature effect other than a delay of ten days in the timing of the annual temperature peak. Measurements of radioactivity in 465 children were completed at the third Pasco elementary school on January 12… more

Cosmic Ray Produced Ar37 and Ar39 Activities in Recently Fallen Meteorites

Description: Several methods of determining meteorite ages depend ages upon nuclides formed by cosmic ray interactions. The tactic assumption is always made that the intensity of cosmic radiation does not vary in time or space. However it is known that the intensity of cosmic radiation at the earth varies with the solar activity. The spectrum of cosmic ray protons and alpha particles exhibit a marked drop at the low energy end (<1.5 GeV) and the intensity in the region appears to follow the 11 year cycle of… more

Characterization of the Organic Material in the 112 BY Tank

Description: In-tank solidification (ITS) of large quantities of goal of aged, alkaline radioactive waste solutions is an integral part of the overall Hanford Waste Management program. Thus, the first ITS unit is currently operational in the 102 BY tank and a second ITS unit recently became operational in the 112 BY tank. The 112 BY tank contains neutralized Metal Recovery Plant waste of the estimated gross salt composition 3.4M NaNO{sub 3}{minus}0.04M NaCl-0.31M NaCH. Tank samples and photographs of the ta… more

Dibutyl Carbitol Solvent Extraction of Polonium-210 from Nitric Acid Solutions of Irradiated Bismuth

Description: Abstract: "A continuous countercurrent solvent extraction process utilizing dibutyl carbitol as the extractant has been developed for separating 210Po from large amounts of associated bismuth. Both laboratory and pilot plant data demonstrate the process is a suitable headend step in recovery of kilogram quantities of 210Po. Typically, the extraction process recovers over 98% of the 210Po, essentially free from bismuth (Bi DF>1500), in a dilute HNO3 solution suitable as a starting material for f… more
