Test plan appendix: WIPP simulated RH TRU waste add-on tests (Additional rock mechanics and waste package performance).

摘要

Simulated RH TRU waste technology experiments have been subjected to heated-environment operations in WIPP Room T since September 1986, as part of program. The scope of the expanded at this time to address a (radioactive) PH TRU waste storage in the WIPP in ''reference'' storage roam configurations, or modifications thereto. specifically, more data are needed on the rock mechanics behavior of the RH TRU storage roams and adjacent pillars, closure deformation for both unlined boreholes and sleeved boreholes, and related waste package performance considerations. The data will be applicable to both the initial five-year period of retrievability (using sleeved boreholes) and the post-retrieval period (with unlined boreholes). In situ testing data will also be compared to 3-dimensional computer modeling of rock mechanics behavior. Such data and associated modeling studies obtained and interpreted as early as possible will allow the WIPP project (including operations, scientific support, and performance assessment) to assess the consequences of maximum thermal loading during the pilot phase of operations. Data and testing experience will support the design, emplacement, and retrieval operations, and related concerns associated with these operations. RH TRU data gathered in the nonradioactive test environment of Room T will be useful and timely to the WIPP project and will minimize testing expenses and difficulties. (ERA citation 18:022935)
