  • The Waste Isolation Pilot Plant (WIPP) is a US Department of Energy repository for the permanent disposal of approximately 180,000 cubic meters of transuranic waste. The repository is located approximately 650 meters below land surface in a bedded salt formation. Microbial degradation of cellulosics in the waste and anoxic corrosion of steel containers and iron-bearing materials in the waste may generate significant quantities of gas. Experimental and analytic studies are currently under way to evaluate the physical and chemical processes that control gas generation and repository response to gas pressurization. These studies indicate that the impact of waste-generated gas inmore » the repository environment is likely to be characterized by strong coupling of chemical, hydrologic, and structural processes. For example, preliminary laboratory experiments suggest that gas generation rates depend on the availability of brine, which is controlled not only by hydrologic conditions surrounding the repository, but also by the rate at which gas pressure increases within the repository. Also, gas pressure in the repository is influenced by creep closure and consolidation of the room contents, which reduces the void volume available to store gas within a disposal room. However, the backstress of elevated gas pressure on the room walls may be capable of reversing room closure. Rigorous analysis of the coupled processes in the repository-rock system requires iterative development of experiments and models that characterize individual processes and system-scale models that characterize process coupling. Rigorous system-scale models are then used to test more streamlined performance assessment models that contain process and/or geometry simplifications in order to carry out probabilistic compliance calculations. 35 refs., 17 figs.« less
  • Several series of nuclear waste package performance experiments are being conducted in situ at the Waste Isolation Pilot Plant (WIPP) facility, near Carlsbad, New Mexico. These nonradioactive experiments are (or are currently in the process of being) emplaced in bedded rocksalt, in several underground test rooms of the WIPP, approximately 650 m below the surface. These tests are being performed by Sandia National Laboratories (with significant participation by Savannah River Laboratory, and others), for the US Department of Energy. Two of these WIPP experiments involve the in situ leaching and interaction testing of simulated (i.e., nonradioactive) high-level waste glasses frommore » several US and international waste form producers: these are the Simulated Defense High-Level Waste (DHLW) Technology Experiments and the WIPP Materials Interface Interactions Test (MIIT). Another test series is the Simulated Contact-Handled and Remote-Handled Transuranic Waste (CH and RH TRU) Technology Experiments. It is the purpose of this paper to provide an overview of: the various test and waste package design details, the experimental objectives, and the status of each test series. The primary focus of this paper will be on the tests containing glass waste forms.« less
  • The Waste Isolation Pilot Plant (WIPP) is a US Department of Energy research and development facility designed to demonstrate the safe, environmentally sound, permanent disposal of transuranic (TRU) nuclear waste that has been generated by US defense programs over the past 40 years. The WIPP facility is situated 26 miles southeast of Carlsbad, New Mexico. The WIPP underground repository is located in the middle of a 3,000-ft-thick bedded salt formation, 2,150 ft below the surface of the Chihuahuan Desert in the Permian Basin. The salt formation is extremely stable and has been in place for 225 million years. The beddedmore » salt formation was selected as the most promising medium for a TRU waste repository. In 1991, the secretary of energy will make a decision on when the WIPP will begin receiving TRU waste shipments to support an initial experimental 5-yr Test Phase. This decision will be made on the basis of operational readiness, environmental documentation, and public acceptance of the WIPP.« less
  • The Waste Isolation Pilot Plant (WIPP), a US Department of Energy (DOE) project located in southeastern New Mexico, has an impressive history in the area of environmental monitoring. When the project was first established by Congress, one of the paramount requirements was the development of site characterization data that included environmental assessments in and around the site location. Along with the site characterization data came the development of both radiological and nonradiological monitoring programs for the project. The programs that have grown out of initial data gathered have continued to be refined and expanded to encompass on- and off-site monitoringmore » of the environment. Developments support the work associated with the no-migration determination model and the methodology for comparative assessment of chemical and radionuclide risks. As work progresses in the test phase of WIPP, the data from the environmental programs will continue to support work in the area of volatile organic compound sampling systems and the maintenance of these systems.« less
  • The Waste Isolation Pilot Plant (WIPP) is a research and development project of the U.S. Department of Energy (DOE) that is designed for storage of contact-handled (CH) and remotely handled (RH) transuranic (TRU) waste generated by U.S. defense activities. The WIPP major facility construction is complete, as are major preoperational audits, checkouts, and demonstrations. During the initial 5-yr WIPP pilot phase, CH and RH TRU waste will be stored in a fully retrievable mode. In the next phase, involving full-scale operations, TRU waste will be emplaced in a permanent disposal configuration. Several major institutional issues will require resolution prior tomore » the commencement of the initial pilot plant phase. WIPP mission, objectives, management and accomplishments are presented. Unresolved issues regarding initiation of the WIPP disposal phase are also discussed.« less
