Inventory planning and scheduling at the Los Alamos National Laboratory nuclear facility (TA-55) has become increasingly demanding given the limited supply of nuclear materials available for weapons production. This limitation comes from the shutdown of nuclear production reactors as well as the declaration of materials excess to national security within the DOE complex. The materials that have been declared excess to national security cannot be used in support of nuclear weapons activities and must be appropriately dispositioned. The matrices of the excess materials and the materials in the weapons; stream are often similar, if not identical, and must be processed and/or packaged utilizing the same personnel and facility resources. In order to segregate these materials and continue weapons production and dispositioning operations concurrently, careful tracking at the item level is required. Scheduling and campaigning of these materials must also be carefully monitored in order to meet both nuclear weapons production schedules as well as dispositioning milestones. All planning activities must consider the impact of processing operations on severely constrained resources including the special nuclear materials storage vault, the nondestructive assay laboratory, and the waste management and shipping operations. This paper details the methodologies and the use of simulation and other computerized tools by the Nuclear Materials Technology Division materials management organization at TA-55. These tools assist in predicting materials and resource availability and optimizing the inventory planning activities.
