This article describes the depth dimensions for the Piton Event Yellow device, which was fired on May 28, 1970.

Data are reported on the radioactivity of environmental samples collected from locations within the Hanford plant boundaries during the last six months of 1969. Data are included on: the total alpha activity and content of / sup 90/Sr and tritium in samples of Columbia River water; the total BETA activity of samples of drinking water; the total alpha , BETA , and gamma activity of samples of surface wnters; the total BETA activity and /sup 131/I content of samples of surface air; and the total alpha , BETA , and gamma activity and content of /sup 95/Zr, /sup 106/Ru, /sup 134/Cs, /sup 137/Cs, /sup 140/Ba, /sup 144/Ce, /sup 238/Pu, /sup 239/Pu and /sup 240/Pu of air filter samples. Est imates were made of the average external gamma - radiation exposure rates of personnel. (CH)

The purpose of this document is to discuss the flowsheet and the related processing equipment with respect to nuclear and chemical safety. The analyses presented are based on equipment utilization and revised piping as outlined in the design criteria. Processing of thorium and uranium-233 in the Purex Plant can be accomplished within currently accepted levels of risk with respect to chemical and nuclear safety if minor instrumentation changes are made. Uranium-233 processing is limited to a rate of about 670 grams per hour by equipment capacities and criticality safety considerations. The major criticality prevention problems result from the potential accumulation of uranium-233 in a solvent phase in E-H4 (ICU concentrator), TK-J1 (IUC receiver), and TK-J21 (2AF pump tank). The same potential problems exist in TK-J5 (3AF pump tank) and TK-N1 (3BU receiver), but the probabilities of reaching a critical condition are not as great. In order to prevent the excessive accumulation of uranium-233 in any of these vessels by an extraction mechanism, it is necessary to maintain the uranium-233 and salting agent concentrations below the point at which a critical concentration of uranium-233 could be reached in a solvent phase.

We discuss the possibility of using synchrotron radiation to form electron rings having a very high electric field to hold the ions inside the ring. The formulas describing bow the energy and the dimension of the ring change under the effect of synchrotron radiation are derived, and a numerical example is given.

This report recommends developing a statistical model to characterize the three-dimensionall pattern of thermal plumes, It indicates the danger of drawing detailed conclusions on the basis of a small number of observations, and emphasizes the need for proper interpretation of empirical measurements, Two reports, on the discharges (1) from the Dresden Power Station into the Illinois River and (2) from Waukegan Station into-Lake Michigan are analyzed. In conclusion, a plan for interpretation of temperature measurements is recommended.

The leachabilities of /sup 90/Sr, /sup 239/Pu, and /sup 137/Cs from solids in Tank 108-SX were determined. Through 21 leach cycles covering a 3.5 day period, 63 volumes of leachate removed 1.4, 4.6, and 19.2% of the /sup 239/Pu, /sup 90/Sr, and /sup 137/Cs, respectively, from the 108-SX solids. With the exception of the first few leachates, the /sup 239/Pu concentrations in the leachates were less than maximum permissible concentration in drinking water for 168-h/wk exposure. A composite of the TK-108-SX leachate was passed through a column containing typical Hanford soil. Column distribution coefficients with 108-SX leachate of 14, 24, and 20 were obtained for /sup 239/Pu, /sup 90/Sr, and /sup 137/Cs, respectively, indicating appreciable sorption of all these radionuclides by the soil. The radionuclides were not readily removed from the loaded soil columns with 12 column volumes of dilute leachate solution. Laboratory results with the 108-SX sludge were carefully evaluated to determine their significance to the overall analysis of the safety of long-term storage of Redox sludge in existing underground tanks. The primary deterrent to movement of the radionuclides from such solids to the water table is the absence of moving water in the storage zone. Incident precipitation does …

This experiment will examine muon-proton inelastic scattering for virtual-photon energies of 10 to 110 GeV and for |q{sup 2}| values of 0.2 to 20.0 (GeV/c){sup 2}. The virtual-photon total cross sections {sigma}{sub t} + {epsilon}{sigma}{sub s}, or the equivalent expression in W{sub 1} and W{sub 2}, will be measured over this range of virtual-photon energies and q{sup 2} values. Some separation of {sigma}{sub T} and {sigma}{sub S}, or equivalently W{sub 1} and W{sub 2}, will be made. The multiplicity, momentum spectra and angular spectra of the charged hadrons produced in this reaction will be measured. Some channels such as {mu} + P {yields} {mu} + P + P{sup 0} will be isolated and completely analyzed. The experiment uses a hydrogen target, wire spark chambers and an analyzing magnet of conventional design.

The authors propose to use the 0{sup o} neutral beam planned for Experimental Area 2 to measure differential cross sections for np elastic scattering in the diffraction region over the energy range of from 40 to 200 GeV and also total cross sections for neutrons on protons, deuterons, and other nuclei over the same energy range. The proposed experiments would use techniques previously developed by the authors in similar experiments at the Bevatron and the AGS. Most of the apparatus already exists. The two experiments could be run in the same beam, either simultaneously or sequentially. The experiments are simple and place very modest demands on accelerator performance.
