NMMSS is the U.S. government's information system containing current and historic data on the possession, use, and shipment of nuclear materials. This centralized database contains accounting data and other related nuclear industry information collected from U.S. government and commercial nuclear facilities and provides reports to facilities and other interested parties, primarily U.S. government offices, charged with the management and safeguarding of nuclear materials. As many as 1,000 routine and requested reports are developed on a monthly basis.

For the last ten years, NAC International, located in Atlanta, GA, successfully operated NMMSS for DOE and the Nuclear Regulatory Commission (NRC). In 2007 it was decided to relocate NMMSS to DOE Headquarters to better facilitate interagency coordination and cooperation, and to reduce overall operating costs by utilizing the existing DOE infrastructure to provide security and administrative functions.

Prior to the move to DOE Headquarters, a software upgrade, funded by the DOE and NRC, will be implemented, tested, validated and accepted. The upgrade will enable NMMSS analysts to use a more user friendly database application for performing daily accountability checks, backing up transaction and inventory databases, and data generation.

One of the necessary modifications required in the recently developed DOE NMMSS User Guide was to ensure that the guide reflected the FY 2009 NMMSS operations transition to DOE Headquarters. DOE users can obtain a copy of the recently approved user guide instructions by downloading the .pdf file on the new NMMSS website at: http://www.hss.energy.gov/nmmss/.

NUREG/BR-0006 and -0007 provide the NRC reporting instructions for input into NMMSS for special nuclear material (SNM) and source material which apply to NRC and Agreement State licensed facilities. Links to download copies of the NUREGs, including the revised NUREG/BR-0006 to be effective January 2009, can be found on the new NMMSS website at: http://www.hss.energy.gov/nmmss/.

Links for downloading hard copies of the recently approved DOE/NRC 741 form for transaction reporting and 742 forms for physical inventory reporting can also be found on the new NMMSS website at: http://www.hss.energy.gov/nmmss/.

DOE contractors and NRC licensees can also refer to the new web site for other information on any changes and updates concerning NMMSS including the information on the changes related to the FY 2009 operations transition to DOE-HQ.
