Proceedings of the Sixth Meeting of the International Collaboration on Advanced Neutron Sources (open access)

Proceedings of the Sixth Meeting of the International Collaboration on Advanced Neutron Sources

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.

Side-by-Side Comparisons of Evacuated Compound Parabolic Concentrator and Flat Plate Solar Collector Systems (open access)

Side-by-Side Comparisons of Evacuated Compound Parabolic Concentrator and Flat Plate Solar Collector Systems

Three liquid-based solar heating systems employing different types of solar collectors were tested side by side near Chicago, Illinois for one year. The three different types of collectors were: (1) a flat plate collector with a black-chrome coated absorber plate and one low-iron glass cover; (2) an evacuated-tube compound parabolic concentrator (CPC) with a concentration ratio of 1.1, oriented with tubes and troughs along a north-south axis; and (3) an evacuated-tube CPC collector with a concentration ratio of 1.3 and one low-iron glass cover, with tubes and troughs oriented along an east-west axis. Results indicate that the flat plate collector system was the most efficient during warm weather, but the CPC systems were more efficient during cold weather, but the CPC systems were more efficient during cold weather, and the CPC systems operated under conditions too adverse for the flat plate collector. The computer simulation model ANSIM was validated by means of the side-by-side tests. The model uses analytical solutions to the storage energy balance. ANSIM is compared with the general simulation TRNSYS.

Intergranular Crack Propagation Rates in Sensitized Type 304 Stainless Steel in an Oxygenated Water Environment (open access)

Intergranular Crack Propagation Rates in Sensitized Type 304 Stainless Steel in an Oxygenated Water Environment

Intergranular stress-corrosion crack (IGSCC) propagation rates were measured in three heats of sensitized Type 304 stainless steel (SS) as a function of sensitization in an environment of high-purity water with 8 ppm oxygen, using a fracture mechanics approach. Specimens were sensitized using controlled furnace heat treatments and the degree of sensitization was measured by the electrochemical potentiokinetic reactivation (EPR) method. Active loading tests were performed on standard specimens over a range of intensities. Crack lengths were determined by compilance measurements using in-situ high-temperature clip gage or LVDT methods, optical metallography on the side faces of the specimen, and fractography of the cracked surface after completion of the tests. The optical metallography measurements did not provide useful estimates of crack lengths, because large variations in IGSCC propagation across the thickness of the specimens occurred. The effects of the degree of sensitization on the IGSCC propagation rate are obscured by the data scatter. However, it seems clear that these variables do not lead to order-of-magnitude changes in the crack propagation rate.

Physics Division Annual Review: 1 April 1982-31March 1983

The research program in nuclear physics in the Physics Division spans a broad range of activities and contributes to many of the major questions in the discipline. Activities may be roughly divided into three broad categories. Research with the tandem-linac in heavy-ion physics is doing well, though laboring under severe budgetary constraints, and outside use of the facility has increased substantially. Progress on the construction of the full ATLAS facility is coming along expeditiously and it is expected to be completed on schedule in 1985. In medium-energy physics, activities are continuing at LAMPF, as well as other accelerators, though considerable effort was devoted this year to the preparation of a proposal for a national electron accelerator facility.

Environmental Surveillance of the Palos Park Forest Preserve (open access)

Environmental Surveillance of the Palos Park Forest Preserve

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 …

Shellside Waterflow Pressure Drop and Distribution in Industrial-Size Test Heat Exchanger (open access)

Shellside Waterflow Pressure Drop and Distribution in Industrial-Size Test Heat Exchanger

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.

Tube Vibration in Industrial-Size Test Heat Exchanger (90° Square Layout) (open access)

Tube Vibration in Industrial-Size Test Heat Exchanger (90° Square Layout)

Tube vibrations in heat exchangers are being systematically investigated in a series of tests performed with an industrial-size test exchanger. Results from water-flow tests of eleven different tube bundles, in six- and eight-cross-pass configurations on a 90 degree square layout with a pitch-to-diameter ratio of 1.25 are reported. The test cases include full tube bundles, no-tubes-in-window bundles, finned tube bundles, and proposed field and design fixes. The testing focused on identification of the lowest critical flow-rate to initiate fluid-elastic instability (large amplitude tube motion) and the location within the bundle of the tubes which first experience instability. The test results are tabulated to permit comparison with results obtained from previous tests with a 30 degree triangular layout tube bundle. Instability criteria are evaluated preliminarily. Pressure drop data are also generated and reported.
