Abstract:
At present the inspection program of security of radioactive materials only looks at the presence of security components, but does not include the measurement of physical protection system effectiveness. This research aims to develop an inspection checklist for evaluating the effectiveness of physical protection system at Categories 1 and 2 radiation facilities. The checklist is developed based on the security objectives of the IAEA’s minimum standard requirements. To meet the objectives, the checklist in the form of questionnaire was created to evaluate each security elements, which are access control, detection, delay, response, security culture, and security management. Scoring criteria are established. The physical protection system will be effective when all security elements meet their objectives. Five samples, which already have the physical protection system installed, are chosen as the test subject for the checklist. The checklist result is compared against the result from the Estimate of Adversary Sequence Interruption (EASI) model, which is a computerized program for evaluating physical protection system effectiveness as the probability of interrupting an adversary in an adversary path. It is found that the checklist result and the EASI result are similar in the case of theft.
