Nuclear Safeguards Education Portal


The Nuclear Safeguards Education Portal (NSEP) was launched in May 2009 and is aimed at providing education and outreach to those with an interest in enhancing security of nuclear materials and facilities.  Initial funding for NSEP was provided by the Office of Nonproliferation and International Security (NA-24) of the U.S. National Nuclear Security Administration (NNSA). Additional courses have been developed under the sponsorship of the NNSA and the US Department of State's Partnership for Nuclear Security. Due to the increasing number of security-related courses being added to the portal, the name was changed in 2015 to the Nuclear Security & Safeguards Education Portal (NSSEP). NSSEP is maintained by the Nuclear Security Science & Policy Institute (NSSPI) at Texas A&M University and was developed through the work of NSSPI and Texas A&M Department of Nuclear Engineering faculty, staff, and students.
