Physical Protection Systems

A Physical Protection System (PPS) integrates people, procedures and equipment for the protection of assets and/or facilities against theft, sabotage, and other malevolent human acts. It can be applied to either facilities or transportation vehicles.

According to the IAEA (INFCIRC/225/Rev.4), the objectives of the State's physical protection system should be:

  • To establish conditions which would minimize the possibilities for unauthorized removal of nuclear material and/or for sabotage 
  • To provide information and technical assistance in support of rapid and comprehensive measures by the State to locate and recover missing nuclear material and to cooperate with safety authorities in minimizing the radiological consequences of sabotage.
