[en] This report covers the progress made during FY 78 in the various tasks of the Waste Management Technical Support Project which the Lawrence Livermore Laboratory is conducting for the Nuclear Regulatory Commission (NRC). The project's goal is to develop a technical base to be used by the NRC in developing regulations and regulatory guides for the disposal of radioactive waste in deep geologic repositories. The report covers primarily the ongoing work of Task I: Waste Form Performance and Task II: Site Suitability. Results from these and other tasks are summarized and referenced. All analyses and conclusions are preliminary and do not reflect NRC positions. 25 figures, 14 tables
