An accelerator group was established at ANL by the request of KFA-Juelich to carry out a conceptual design study and cost estimate for a rapid-cycling synchrotron as a possible first stage program on spallation neutron sources at KFA-Juelich. This set of notes is the individual notes which form the basis of the final report under this proposal prepared in January 1983. This document contains 37 papers/notes for Advanced Accelerator Development - Neutron Source Series Notes...numbered AAD-N-1 through AAD-N-37. Each note or paper is written by various authors.

Representatives of the Laboratories of the International Collaboration on Advanced Neutron Sources gathered between 28 June and 2 July, 1982 at Argonne National Laboratory for their sixth meeting, ICANS-VI. The meeting was the first opportunity for participants to see Argonne's Intense Pulsed Neutron Source, which went into full operation in August, 1981, and in an important sense celebrated the coming-on-line of this most recent entry into the world's complement of the new generation of neutron sources. The main topics of the meeting were "Targets and Moderators" and "Neutron Scattering Instrumentation", following what has become the customary rotation of subjects. An additional topic, "Nuclear Data and Codes" emerged this time as a separate entity, closely related to the Targets and Moderators subjects. These Proceedings are organized roughly in the order and organization of presentations. In addition, a record of some of the discussions is included following each Status Report, and separate summaries of discussions on various subjects of the topical sessions. The manuscripts have been reproduced essentially as received.

Abstract: "An updated geologic reconnaissance map was prepared of the vicinity of Cypress Creek Dome, Mississippi, at a scale of 1:24,000. Compilaion of previous work, field mapping, and heavy material analyses were used to prepare the map."

Abstract: "A geologic reconnaissance map was prepared of the supradomal area of Keechi Dome, Texas, at a scale of 1:24,000. To do this, available data were compiled, and field checking and new mapping were done where access was permitted."

Abstract: "A geologic reconnaissance map was prepared of the supradomal area of Richton Dome, Mississippi, on a scale of 1:24,000. To do this, previous work was compiled and consolidated, and field mapping and heavy mineral analyses took place."

Abstract: "A geologic reconnaissance map was prepared in the area of Vacherie Dome at a scale of 1:24,000. To do this, the available data were compiled, resistivity surveys were conducted, and reconnaissance field mapping took place. Then all the information was consolidated for the map preparation."

From introduction: The accurate prediction of phase equilibria plays an important. role in the chemical process industries. A grief overview of final phase equilibria predictive techniques is presented with special emphasis on methods in current use in industry. Areas were better fundamental understanding will lead to improved models are discussed whenever possible.

Purpose and scope: The purpose of the study was to determine whether a thin layer of volcanic ash measurably affects aquatic environments. Study objectives were to: (1) Determine the amount of ash initially deposited in Big Creek basin and the amount remaining 1 year after the eruption, and (2) describe the impact of ash on water quality and benthic invertebrate communities.

This is the second report describing an ongoing environmental surveillance program conducted at the Palos Park Forest Preserve near Chicago, Illinois. The Preserve was a site of a nuclear research laboratory (Site A) from 1943 to 1956 and a radioactive waste burial site (Plot M) from 1944 to 1949. An extensive radiological characterization of the site was conducted from February 1976 to August 1977, and tritium in the form of water was found to be the only radionuclide that migrated from the nuclear facilities. The results were published in US Department of Energy Report DOE/EV-0005/7. The present report summarizes the earlier findings and gives the detailed results of the work from August 1977 through December 1981. The vertical and horizontal distribution of tritium within the glacial till was determined from measurements of tritium in soil moisture. Chemical and radiochemical analyses were performed on a number of wells in the area. Tritiated water continued to be the only species that was observed to have migrated from the Plot M area. Migration from the Site A area was not observed. The concentration of tritium at the Red Gate Woods well, 1200 ft down-gradient from Plot M, continued to show the seasonal fluctuations …

The shellside pressure drop between the inlet and outlet nozzles as well as the pressure drops through individual sections of different shell-and-tube test-exchanger configurations are measured under water flow. The segmentally baffled test exchanger is nominally 0.6 m (2 ft) in diameter, 3.7 m (12 ft) long and contains a tube bundle of 19 mm (0.75 in.) outside-diameter tubes. Results are reported of 24 test cases obtained from various combinations of parameters: 30 degrees triangular or 90 degrees square tube layout patterns (all on a 1.25 pitch-to-diameter ratio), numbers of cross-passes, sizes of nozzles, plain or finned tubes, and full or special fix tube bundles. The exponential change of pressure drop as a function of flow-rate is also investigated and an attempt is made to calculate nozzle losses.

Purpose: This investigation by the U.S. Geological Survey, in cooperation with the Warminster Municipal Authority, has three purposes: (1) to determine how urbanization has affected ground water and low streamflow in Warminster Township and parts of the surrounding municipalities; (2) to describe the hydrologic system; and (3) to assess the availability of ground water.
