During decommissioning of the Tokai Reprocessing Plant (TRP), the Japan Atomic Energy Agency (JAEA) will build a new facility to prepare high-activity solid waste for final disposal and must develop an advanced measurement system for this waste that meets requirements to implement appropriate nuclear material accounting and control (NMAC), as well as effective nuclear security overall. Based on their long history of collaboration on non-destructive assay technologies for nuclear fuel cycle facilities, JAEA, the U.S. Department of Energy / National Nuclear Security Administration (DOE/NNSA) and Los Alamos National Laboratory (LANL) have agreed to cooperate on joint design and development of an Advanced Hull Measurement and Monitoring System (A-HMMS) for TRP. The paper summarizes work already completed and outlines next steps in the cooperation between JAEA, DOE/NNSA and LANL on development of A-HMMS in the coming years.
