Research on backfill (= overpack) design at The Pennsylvania State University has focussed on the stability of such materials under repository conditions, the interactions of these materials and waste under repository conditions, and the sorption and fixation properties of backfill materials. Montmorillonite among clay minerals and mordenite and clinoptilolite among zeolites have been identified as the best backfills based on the present studies. Areas for further research include thermal stability studies of backfill materials under repository conditions in conjunction with natural analogs, waste-backfill interactions and design of backfill materials for purposes such as maintaining a reduced environment and keeping the repository dry.
