[en] This report is a compilation of geotechnical data presented as plots for each active instrument installed in the underground at the Waste Isolation Pilot Plant (WIPP) through June 30, 2005. A summary of the geotechnical analyses that were performed using the enclosed data is provided in Volume 1 of the Geotechnical Analysis Report (GAR).
[en] This work presents a first application of an open source SPH model (DualSPHysics) to study the dynamics of a debris flow, with reference to the dry debris flow of Alverà, close to Cortina d’Ampezzo (Belluno, Italy). In this part of the Dolomites, debris flows are usually formed by large boulders within the fluid matrix. The adopted Lagrangian approach has allowed to describe the relative motion of a boulder immersed in a fluid mixture. From the numerical results, it has been observed that the boulder travels a greater distance along the channels, when water drives it. On the other hand, without the water thrust, the same boulder would halt much earlier. Furthermore, in all the simulated cases, it has been observed that the boulder stops when a natural narrowing is encountered along the channel bed. (paper)
[en] The shielding calculations for the SNO detector which were reported previously in AECL-9393 have been updated and extended in this report. These calculations are based on measured Th and U concentrations in the norite at the 2000 m level, on the composition of sulfurcrete as the shielding wall and on recently evaluated (alpha, neutron) yields. The effect of asymmetries in the detector design have been considered and a comparison between measured and calculated gamma and neutron backgrounds in the mine have been made. The report assumes reader familiarity with its predecessor, AECL-9393
[en] SNL-9 (permitted by the State Engineer as C-2950) was drilled to provide geological data and hydrological testing of the Culebra Dolomite Member of the Permian Rustler Formation within a proposed re-entrant of the margin of halite dissolved from the upper part of the Salado near Livingston Ridge. SNL-9 is located in the southeast quarter of section 23, T22S, R30E, in eastern Eddy County, New Mexico. SNL-9 was drilled to a total depth of 845 ft below the ground surface. Below surface dune sand and the Berino soil, SNL-9 encountered, in order, the Mescalero caliche, Gatuna, Dewey Lake, Rustler, and uppermost Salado Formations. Two intervals were cored: (1) from the lower Forty-niner Member through the Magenta Dolomite and into the upper Tamarisk Member; and (2) from the lower Tamarisk Member through the Culebra Dolomite and Los Medanos Members and into the uppermost Salado Formation. Geophysical logs were acquired from the open hole to total depth, and the drillhole was successfully completed with a screened interval open across the Culebra.

[en] Uranium occurs in several environments in the Circum-Ungava Belt. Newly recognized styles of mineralization in the Labrador Trough include occurrences hosted by black, cherty, and phosphatic shale and by dolostone. An additional occurrence in albitized rocks is documented. In general there are potential sources for uranium within clastic rocks, particularly in black shales, potential sources for scavenging agents in sequences containing evaporites, and appropriate thermal agencies and structural traps provided by widespread volcanism and attendant intrusions. Together these provide excellent conditions to form high-grade vein deposits in albitites within the Circum-Ungava Belt
[en] Process features of producing of magnesium astringent substances on the base of magnesite and dolomite and their characteristic arc examined. The potential possibility of creation of compositional material based on caustic dolomite, that was obtained from natural dolomite raw materials of Belarus, for immobilization of radioactive waste is presented.
