[en] This paper presents the status of the BWIP waste package materials testing, modeling, and design activities and plans for continuing these activities through FY 1984. The first in a series of design activities leading to the final design of waste packages that will reliably meet federal performance criteria has been completed. These activities have led to the development of waste package conceptual designs for commercial and defense high-level waste (borosilicate glass) and spent fuel rods. Planned engineering studies, together with an improved materials data base, will provide the necessry information for the preparation of waste package advanced conceptual design requirements during FY 1984. 12 references, 5 tables
