Strengthen of Physical Protection Regimes for Radiological Facility

The function of Physical Protection Regimes (PPR) should meet three basic elements (detection, delay, and response) and it is required to protect the facility against; possibility bombing, sabotage, and theft. The system must be fast in performance to achieve sufficient time for the arrival of response forces and complete the defense about the property in a timely, thwart the adversary and neutralize on the implementation of its mission. The performance of the physical protection system should be designed to oppose and limit the capabilities and tactics of the attacker (force, deceit and stealth) toward the entity that contains modern tactics and different concept, and in the way to work is a barrier against the attacker is difficult to penetrate and overcome it. In this paper an improving of the physical protection system effectiveness for a radioactive sealed sources facility is presented. The hardest scenarios will be used as a tested for the performance of this system based on the principles of physical protection. If the evaluation reveals any weakness, the initial system design must be redesigned to correct the vulnerabilities and another analysis of the redesigned system is performed. (author)
