A column-flow cesium migration experiment has been conducted in support of the safety assessment program for the Waste Isolation Pilot Plant (WIPP) in Southeastern New Mexico. The column was a monolithic cylinder of Magenta dolomite obtained from a core sample drilled near the proposed WIPP site. The fluid was a Magenta equilibrated de-ionized water solution that had been doped with 0.001 ppM of /sup 137/Cs. The experiment ran continuously for an 18 month period at flow rates comparable to those measured for natural groundwater at the site. After flowing for 18 months, the apparatus was disassembled and the dolomite column examined for cesium distribution. Cross sectional radiographs of the sample showed that most of the cesium had penetrated only 0.4 cm into the solid Magenta column with a well defined wave front. On the other hand, trace quantities (2 x 10/sup -7/ ppM) of /sup 137/Cs were detected in effluent samples collected during the experiment. The distribution coefficient (120 ml/gm) calculated (assuming porous flow) from the average depth of cesium penetration (0.3 cm) is considerably less than the value obtained from a batch equilibration measurement made on the same system (650 ml/gm), indicating that cesium will migrate through Magenta rock …

Introduction: This report is a brief review of the uranium and/or vanadium mining in the eastern Carrizo Mountains, San Juan County, New Mexico and Apache County, Arizona. It was prepared at the request of the Navajo Tribe, the New Mexico Energy and Minerals Department, and the Arizona Bureau of Geology and Mineral Technology. As this report deals only with historical production data, the reader is referred to reports by Blagbrough and Brown (1955), Masters and others (1955), and Stokes (1951, 1954) for descriptions of the geology and ore deposits. Figure 1 shows the locations of the mines and the production is summarized in Table 1 and Figure 2. A separate report (Chenoweth and Learned, 1980) covers the production history of the northern and western Carrizo Mountains.

From abstract: This report presents a preliminary evaluation of design concepts for the eventual sealing of the shafts, drifts, and boreholes at the Waste Isolation Pilot Plant Facility. The purpose of the seal systems is to limit the flow of water into, through, and out of the repository.

From Introduction: "The Clifton Quadrangle, Arizona and New Mexico (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits. An area of approximately 20,600 km2 was evaluated during this study."
