NMMSS and International Safeguards in the United States

In 1980, the Agreement between the United States (US) and the International Atomic Agency (IAEA) established the requirement for the US to report to the IAEA nuclear material subject to the Agreement. The Nuclear Materials Management and Safeguards System (NMMSS) is the US Government’s information system containing data on the possession and shipment of nuclear materials. The Department of Energy (DOE) and Nuclear Regulatory Commission (NRC) rely on the NMMSS to generate reports to fulfill the US Government’s commitments to the IAEA. Pursuant to the negotiations between the US and the IAEA, the US agrees to: Report to the IAEA all shipments and receipts of source or special fissionable material to a Non-Nuclear Weapons State (NNWS) for peaceful purposes as well as domestic use of nuclear material at facilities selected by the IAEA. The NMMSS is responsible for collecting the required data, formatting it into the proper format and transmitting it to the IAEA. • INFCIRC/288 reports are generated from activities that are part of a Voluntary offer made by the US. • INFCIRC/207 reports are generated from Import/Export activities throughout the reporting community. The NMMSS utilizes the standard reporting vehicles for collecting data from Nuclear Facilities (DOE/NRC Form 741, DOE/NRC Form 742, DOE/NRC Form 742C and DOE/NRC Form 740M) and reformats the data received to meet the IAEA requirements as outlined in the Subsidiary Arrangement General Part (Code 10). NMMSS prepares standard reports and provides them to the IAEA. These reports document and report the domestic inventories, material balances and transactions for the US nuclear industry. The NMMSS is tasked by the US Government to provide the IAEA with accurate and timely data and to assist in the resolution of any issues that may arise from said reporting. The NMMSS works to develop and maintain a cohesive working relationship between the US government, the IAEA, the US nuclear industry and itself.
