On July 22, 1986, the first series of in situ tests involving burial of simulated nuclear waste forms and proposed package components was begun in the United States. This effort represented a joint program conducted by both Sandia National Laboratories/WIPP and SRL and involved the burial of samples in 50 emplacement boreholes, 650 meters below the earth in the rock salt site at WIPP near Carlsbad, New Mexico. The program is called the Materials Interface Interactions Tests or MIIT and the test matrix included 980 waste form samples consisting of 15 different compositions and waste forms supplied by seven different countries. In addition, 278 metal samples of eleven different potential waste canister or overpack materials (some prestressed, others containing pits, and many containing welds) were also involved in this study along with 587 salt and backfill geologic specimens. The entire MIIT effort involves 1845 total specimens. In January and February of 1987, the first series of waste glass and metal samples was removed from burial after being in test for six months. These represented the first group of samples that will be studied and evaluated in the five year MIIT program. This paper provides an overview of the MIIT program to update this effort. 13 refs.
