4 Overall Progress in ANL's EMT Demonstration Project

The committee will perform a full evaluation of ANL's EMT demonstration project when it has been completed; this report does not attempt such a broad-based assessment. Nevertheless, Appendix B provides a list of the demonstration project's success criteria together with ANL's stated accomplishments as presented to the committee in its June and October 1998 meetings. The committee's assessment of progress as stated in this report was based on several sources of information: the accomplishments reported by ANL during the committee's meetings, follow-up Q&A between the committee and ANL personnel, and written documentation provided by ANL (and cited in this report).

The committee concludes that the accomplishments reported by ANL concerning its EMT demonstration project are an accurate measure of progress toward the goal of meeting the success criteria. As noted in this report, the committee has some concerns about the testing procedures currently being employed for the purpose of meeting success criterion 2, goal 2. The tests currently used, i.e., corrosion tests, vapor hydration tests, and attribute tests, are appropriate for developing metal waste specifications. However, the committee believes that the conditions utilized in these tests are too mild to yield sufficient information about the behavior of the metal waste form under more stringent conditions.

In addition, there remain engineering problems that need to be resolved prior to the end of the demonstration project. Problems with the scrapers of the ACM for the Mark-V HTER are formidable and must be resolved if this equipment is to be used successfully.
