Disposition of legacy materials at LBNL and reuse of valuable items in target preparation

摘要

One of the most demanding missions of the United States Department of Energy (DOE) is to manage the radioactive waste. Lawrence Berkeley National Laboratory (LBNL) gets its share of radioactive materials and waste but at a much smaller scale than other national labs. Disposition of legacy materials at LBNL includes characterization and purification, reuse of valuable materials, and submitting waste items in accordance with federal and state regulations. During the clean up of legacy materials at LBNL, several items were identified for use in collaboration with the CEA/DSM under the Mini-Inca program to perform transmutation studies. Cm and Np targets were prepared using an electroplating technique. Additional targets of Pu, Am, and Cf are planned for the next set of experiments. An overview of the clean up operation of two facilities will be given. An outline of items assigned to the collaboration and a brief description of the target preparation and electrodeposition set-up will be provided.
