The Institute of Nuclear Materials Management (INMM) is an international technical and professional organization that works to promote safe handling of nuclear material and the safe practice of nuclear materials management through publications, as well as organized presentations and meetings. The INMM's headquarters is located in Deerfield, Illinois in the United States, but its members are located around the world including Europe, Asia, South America and North America. There are more than 1,100 members and 32 chapters. Les Shephard, vice president of Sandia National Laboratories' Energy, Security, and Defense Technology Center, said in February 2009 of the INMM and the American Nuclear Society, Structure INMM is led by an executive committee of nine members, including a president, vice president, secretary, treasurer, four members-at-large, and the immediate past president. In addition, INMM has several standing and two technical committees. Many organizations, such as Los Alamos National Laboratory and Brookhaven National Laboratory, are Sustaining Members of the INMM. Technical divisions In 2010, the INMM Executive Committee approved a restructuring of the Institute. This included changes in the technical divisions. Some were merged and a new division was created. The technical divisions are: Facility Operations International Safeguards Materials Control and Accountability Nonproliferation and Arms Control Nuclear Security and Physical Protection Packaging, Transportation and Disposition The division is the focal point for information and activities related to the physical protection of nuclear materials, nuclear facilities, and other high-value assets and facilities. Until 2010, the INMM had six technical divisions: International Safeguards, focusing on the development of effective international nuclear material safeguards, and working to advance safeguard procedures and technology Materials Control and Accountability, promoting and communicating the need for development of technology for the control and accountability of nuclear materials Nonproliferation and Arms Control, promoting research to further international stability with regard to nonproliferation and international arms control Packaging and Transportation and Disposition, promoting technology and research aimed at the packaging and transportation of radioactive materials, including all levels of radioactive waste Nuclear Security and Physical Protection, focusing on research to advance technology for the physical protection of nuclear materials and nuclear facilities Waste Management, promoting research to help find a solution for the worldwide waste management issues, focusing on each step of waste management including handling, processing, storing, and disposal for all radioactive waste Best practices The INMM develops and promotes global "best practices" for nuclear materials management. Best practices are based on
