The function of Physical Protection System (PPS) should meet three basic elements (detection, delay, and response) and it is required to protect the nuclear facility against possibility of 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 time, thwarting the adversary and neutralizing the implementation of its mission.The performance of the physical protection LIQUID LANOLIN system should be designed to oppose and limit the capabilities and tactics of the attacker toward the nuclear facility.

And in this ways it works as a barrier to obstruct the attacker against penetration.In this work an evaluation of the physical protection system effectiveness for a hypothetical facility against sabotage is presented.Proposed sabotage scenarios will be used as an input for this evaluation.

The evaluation process was carried out using the single path computer model (EASI), for the determination of the probability of interruption (PI) as a first metric factor of the PPS effectiveness.The Probability of Neutralization (PN) is computed by the neutralization analysis module as a second metric factor of the PPS effectiveness.The probability of detection and delay time values of detection, delay, communication and response forces action was measured along a specific sabotage path of the adversary.

If the evaluation reveals any vulnerability, the initial system design must be redesigned to correct the vulnerabilities and another analysis of the redesigned system is performed.Keywords: Nuclear facility, Physical security, vibrating-masturbators Sabotage scenarios.
