The Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (ISCN) of the Japan Atomic Energy Agency (JAEA) is developing technologies for nuclear forensics to identify the origin and intended use of nuclear and radioactive materials. In order to share the experience on nuclear forensics analysis and to improve analytical techniques in the international community, the Nuclear Forensics International Technical Working Group (ITWG) regularly holds the Collaborative Materials Exercise (CMX). The ISCN participated in the 7th exercise (CMX-7) this time. This paper reports the experience of the exercise, and discusses nuclear forensics analytical capability of the ISCN based on the review of the exercise.
