Shielding, Efficiency of an Oxychloride-Iron Concrete -- Comparison with Hanford Shield

Description: Radiation attenuation tests were made on both a Hanford shield sample and an iron aggregate oxychloride cement. The measurements consisted of the detection of neutrons throughout the shield by means of gold foils and the detection of y radiation through increasing thicknesses of shield by means of a collimated G M tube with a fixed geometry. These samples were exposed to a pile flux of approximately 1010 n cm2 sec and an accompanying y flux which extrapolated to about 12,000 r hr at the inner f… more

Development of Techniques for Power Production From Mixed Fission Products

Description: "Progress is reported on Phase II of a program for the development of a mixed fission product fueled thermoelectric generator. Materials studies are described in which bonded assemblies of bismuth telluride were life tested up to 3000 hours at 350 to 400 deg F hot junction temperature. Data were too inconsistent to define any satisfactory long-life bonding process. Further work is needed to eliminate the process variables. Insulation studies aimed at determining the thermal conductivity of vari… more

Braze Alloys v.s. Atmospheres : Final Report Project 1325

Description: Summary. At the time this project was initiated, all brazing had been confined to small retorts of ten cubic feet capacity or less. Larger assemblies were scheduled which required retorts of over 100 cubic feet capacity. Hydrogen atmospheres had given the best results, however, there was considerable reluctance to use hydrogen in these large retorts from a safety standpoint. It was thought that thru the use of PMC 2252, an argon - 2 1/2% hydrogen gas atmosphere which in non-explosive, suffici… more

Cycling of /sup 36/Cl labeled DDT in natural systems. Technical progress report

Description: Data are reported on the cycling of /sup 36/Cl-labeled DDT in an old field ecosystem. Data are included on the content of DDT retained in samples of soil, plants, invertebrates, and tissues of small mammals. The body burden of DDT in both earthworms and slugs decreased during the six-year period whereas that of isopods increased, indicating that the food chain sources of the compound differ among soil invertebrates.

Gas Generation Testing of Uranium Metal in Simulated K Basins Sludge and Grouted Sludge Waste Forms

Description: The evolving plan for most of the KE and KW Basin sludges is disposition to WIPP as remote handled (RH) TRU. Because the hydrogen gas concentration in the sealed transportation cask destined for WIPP is limited by flammability safety, the number of containers and shipments to WIPP likely will be driven by the rate of hydrogen generated by the contained uranium metals reaction with water. Therefore, gas generation testing with uranium metal particles of known surface area and immobilized in cand… more

Chemical Processing Department monthly report, April 1959

Description: Production of Pu from separations plants was only 58% of April commitment because of Purex difficulties. UO{sub 3} production, shipments met schedules. Pu shape production and shipments exceeded forecast by 14%. Purex HS column, repaired Oct 1958, developed another leak and was bypassed April 18, resulting in Pu and U that required reprocessing. A Palm recovery run at Purex with all- reducing flowsheet, resulted in 87% recovery and excellent decontamination of product. The prototype dual-pass s… more

Chemical Processing Department monthly report for April 1958

Description: The separations plants operated on schedule, and Pu production exceeded commitment. UO{sub 3} production and shipments were also ahead of schedule. Purex operation under pseudo two-cycle conditions (elimination of HS and 1A columns, co-decontamination cycle concentrator HCP) was successful. Final U stream was 3{times} lower in Pu than ever before; {gamma} activity in recovered HNO{sub 3} was also low. Four of 6 special E metal batches were processed through Redox and analyzed. Boric acid is rem… more

Analysis of Site Response at U1A Hole at the Nevada Test Site From Weak Motion Readings

Description: We utilize weak motion recordings to evaluate the site response at the U1A hole, Nevada Test site to determine the effect on potential ground motion at the drift of the U1A hole 962 ft deep. We estimated the site response amplification of ground motion at the surface relative to the drift with the spectral ratio method. We utilized Fourier amplitude and absolute acceleration response spectra, and confined our study to frequencies of 0.5 to 25.0 Hz (.04 to 2.0 s periods). We identified 8 earthqu… more

Permeation rates for RTF metal hydride vessels

Description: Contamination rates have been estimated for the RTF nitrogen heating and cooling system (NH and CS) due to tritium permeation through the walls of metal hydride vessels. Tritium contamination of the NH and CS will be seen shortly after start-up of the RTF with the majority of it coming from the TCAP units. Contamination rates of the NH and CS are estimated to exceed 400 Ci/year after three years of operation and will elevate tritium concentrations in the NH and CS above 6 {times} 10{sup {minus}… more

Energy Information Administration quarterly coal report, October--December 1992

Description: The United States produced just over 1 billion short tons of coal in 1992, 0.4 percent more than in 1991. Most of the 4-million-short-ton increase in coal production occurred west of the Mississippi River, where a record level of 408 million short tons of coal was produced. The amount of coal received by domestic consumers in 1992 totaled 887 million short tons. This was 7 million short tons more than in 1991, primarily due to increased coal demand from electric utilities. The average price of … more

Development of advanced direct perception displays for nuclear power plants to enhance monitoring, control and fault management. Progress report

Description: With recent theoretical and empirical research in basic and applied psychology, human factors, and engineering, it is now sufficient to define an integrated approach to the deign of advanced displays for present and future nuclear power plants. Traditionally, the conventional displays have shown operators the individual variables on gauges, meters, strip charts, etc. This design approach requires the operators to mentally integrate the separately displayed variables and determine the implicatio… more
