Japan Atomic Energy Agency has started R&D on nuclear forensics technology since Japanese Fiscal Year of 2011. One of main topics of the R&D project is to develop national nuclear forensics library (NNFL) which consists of database and evaluation methodology for interpretation of the attributions of nuclear and other radioactive materials. JAEA has continued to develop a prototype system of NNFL based on data of the nuclear and other radioactive materials that JAEA has possessed in the past research activities. A development of prototype nuclear material database (NMDB) was almost completed with its basic data handling system. Data compiling on the JAEA NMDB has been continued. JAEA also participated in the virtual table top exercise on NNFL named Galaxy Serpent and has continued to study attribution evaluation methodologies using the data in a NNFL. In the next step of the NNFL project, it is planned to carry out the development items; prototype of radioactive materials database (RMDB), image evaluation tool for microscope images, multivariate analysis tools for seizure analysis and knowledge accumulation system for nuclear forensics analysis. This paper presents the current status and future prospects on the prototype NNFL development at JAEA.
