Stress Ellipsoid Determination in a Rock-Burst-Prone Area at a 4,000-Foot Depth, Galena Mine, Wallace, Idaho

Description: Report issued by the Bureau of Mines over a study on "stress determinations in an area known to be under high stress concentration induced by prior mining operations" (p. 2). The geology, procedures, and instrumentation are discussed. This report includes tables, illustrations, and photographs.

Low energy gamma-transitions in Pu{sup 238} and Pu{sup 240}

Description: We investigated electron and gamma spectra of mixtures of isotopes of curium. This was done on a beta spectrometer with double focusing at an angle of {pi}{radical}2 and on a scintillation gamma spectrometer with a 40 {times} 40 mm NAI(Tl) single crystal detector. The observed electron spectrum are interpolated and presented. Also, experimental results of the ratio of conversion at L and M subshells are presented and compared to theoretical values.

Pacific Northwest Laboratory monthly activities report, November 1967

Description: Calculated temperatures permitted in the Columbia River under various suggested regulations were plotted and reported in support of AEC studies. Mechanisms of Environmental Exposure. Measurements of radioactivity were completed in 362 pupils and 5 teachers at Emerson School on November 17. Measurements will begin at the third Pasco elementary school on December 5. Lectures were given at Mark Twain School to the teaching staff on November 20, and to 23 classroom son November 27 through December 1. A lecture was also given to the PTA meeting the evening of November 20 at Robert Frost elementary school in Pasco. Modifications were made to the electronic equipment and to the mobile whole-body counter van to improve the performance of the facility to further protect the NaI crystal from potential cold weather damage. Errors found inn the computer-calculated environmental doses were being corrected at month`s end, and the doses will be recalculated in December.

Pacific Northwest Laboratory monthly activities report, October 1967

Description: The results of a statistical study of Columbia River temperature trends were released on October 18 at the Sixth WSU Hydraulics Conference. The new John Day reservoir is under study for possible beneficial effects on flow regulation. Measurements of radioactivity in 396 children were completed at Captain Gray elementary school, Pasco, Washington on October 19, 1967. Measurements began at the Emerson elementary school in Pasco on October 24, 1967, following lectures to the teaching staff and to each of the 18 classrooms in grades 1 through 6. Computer programming was started in October to determine the frequency distribution, mean, and median values of the environmental radiation dose values calculated last month from several thousand individual adult diet records. Response or game bird hunter-employees to a request for participation in a survey of game bird kills during the current season has been disappointing in spite of several articles in the project newspapers.

Thermal stability of zirconia-s and thoria-base fuels (LWBR Development Program)

Description: Vapor densities and/or dissociation pressures of UO/sub 2/, ThO/sub 2/, ZrO/sub 2/, ThO/sub 2/-8 and -20 wt % UO/sub 2/, and ZrO/sub 2/-20 and -50 wt % UO/sub 2/ were obtained in the range from 2000 to 3000/sup 0/K by the transpiration technique. The UO/sub 2/-ZrO/sub 2/ system exhibited marked positive deviation from ideality, indicative of a strong tendency toward immiscibility. The UO/sub 2/-ThO/sub 2/ system was found to behave almost ideally. On the basis of the vapor pressures of UO/sub 2/ and of ThO/sub 2/ and the activity values it would be expected that compositions containing 1 mole % or more of UO/sub 2/ would volatilize by preferentially losing UO/sub 2/. A composition containing slightly less than 1 mole % UO/sub 2/ should prove to be the congruently subliming composition. O/sub 2/-dissociation pressures were determined for stoichiometric UO/sub 2/ and for a composition on either side of the stoichiometric one. At 2360/sup 0/K, UO/sub 2.03 +- 0.01/, UO/sub 2.00 +- 0.01/, and UO/sub 1.97 +- 0.01/ exhibited O/sub 2/-dissociation pressures of 1 x 10/sup -7/, 4.3 x 10/sup -10/, and 3 x 10/sup -12/ atm, respectively. From determinations of vapor density and measurements of O/sub 2/ pressure, pressure-temperature-composition relations were established for UO/sub 2/ over a small range of compositions encompassing UO/sub 2/./sub 00/.

Effect of S8DR chromium diffusion treatment on the creep rupture properties of processed Hastelloy-N tubing

Description: Process development personnel have been seeking means of improving the (after thermal exposure) adhesion of the S8DR ceramic coating to chromized Hastelloy N tubing. This effort has led to the incorporation of an elevated temperature chromium diffusion treatment prior to the application of the ceramic coating. This report describes the results of tests performed to ascertain the influence of the additional thermal treatment on the 1400/sup 0/F creep-rupture properties of S8DR tubing.
