| Abstract Many of the nuclear and radiological facilities have Physical Security System (PSS). It has been installed from long time; the security systems include many different types of cluster sensors, components and control devices. It should keep the security system component valid and updated, and follows procedures, rules and requirements of the Nuclear Regulatory Authority at the national level and meets IAEA concept and recommendations at the international level. The Evaluation of the PSS efficiency is very necessary requirements, and should be determined. This paper introduces a Hypothetical Nuclear Site for PSS analysis and evaluation process. The work developed an analytical methodology for the evaluation. The Systematic Analysis of Vulnerability to Intrusion (SAVI) computer program is used in PSS evaluation. SAVI determines the most vulnerable paths of an adversary sequence diagram as a measure of effectiveness. The paper determines the vulnerabilities and threat of some physical protection element on the nuclear site and calculates the system win probability. This work explains; the adversary scenario for the most vulnerable path and determine the PSS effectiveness. Each of Time remaining after interruption, and cumulative path delay after critical detection point will be calculated. SAVI Outsider module enables the likelihood of attack interruption to be calculated &finds the set of the most vulnerable 10th worst paths. This work will serve as base guidelines for the decision makers, the application, and evaluation of PSS and provision of counter measure strategies in the nuclear energy facilities.
