Abstract
A laboratory testing program was conducted to evaluate the performance of the Council for Scientific and Industrial Research (CSIR) Doorstopper'' biaxial strain cell. This work was conducted in support of the Basalt Waste Isolation Project's in situ stress measurement program to be carried out within the reference repository horizon. Performance tests were designed to (1) select an adhesive suitable for installation of the Doorstopper, (2) evaluate the component parts of the Doorstopper, and (3) test the performance of the Doorstopper and selected adhesive. Test conditions were selected to simulate those expected at the reference repository horizon during overcoring (temperatures ranging from 40{degree}C to 65{degree}C with a humidity of up to 100 percent). 10 refs.
