Basalt Waste Isolation Program: monthly report
Washington State Department of Natural Resources has completed the reconnaissance mapping of the late Cenozoic sediments within the western half of the Columbia Plateau. The compilation of 1 : 250,000 base maps for the Columbia Plateau and of 1 : 100,000 base maps for the Pasco Basin has been completed by the Washington State Department of Natural Resources. Hydrologic testing of DC-2 continued. Seismograph Services Corporation completed their processing of the seismic test data. The results indicate that the basalt surface can be mapped continuously. Lower horizons can be mapped locally. Preliminary data from Senturion Services, Inc. on the magnetotelluric test suggests that the basalt sequence is about four kilometers thick. Drilling operations were conducted at two locations and hydrologic testing at one location during the reporting period. Coring operations at DC-4 advanced from 749 feet to 1,074 feet. DC-4 is 21% complete based upon a total depth of 5,000 feet. Coring operations at DC-8 advanced from 2,959 feet to 3,956 feet. DC-8 is 96% complete, based upon a total depth of 4,100 feet. The Vitro Engineering Title I effort for facility requirements and site work was essentially completed during the month. Rockwell Hanford Operations reviewed the comment issues and returned them to Vitro Engineering. The facility requirements design covers the facility electrical power and mechanical systems. The site work design covers the roads, parking areas, and embankment construction in the portal areas. Woodward-Clyde Consultants held a workshop to evaluate and rank possible events that could disrupt a deep geologic waste repository. A list of seven of the most significant events has been approved by Rockwell Hanford Operations and the subcontract is proceeding with development of fault trees.
