Abstract |
|
|
| The nuclear protected area (P.A) inside a limited access area in the nuclear facilities, containing category I or II nuclear material, and/or sabotage targets surrounded by a physical barrier with additional physical protection measures taken to prevent an adversary from achieving an undesirable consequence and to mitigate or minimize the consequences if the adversary initiates such a malicious act. P. A contains nuclear vital areas (V.A) which contain equipment, systems, or devices, or nuclear material, the sabotage of which could directly or indirectly lead to high radiological consequences. The alarm system control panels that are associated with the alarms from security sensors receive alarms each time during the intrusion process. At times, the screens of the alarm system & access control systems have hundreds of alarms as a log of events generated in one hour, The operator and guards who monitoring the facility finds it very difficult to handle and distinguish with the important alarms generated by the alarm system among hundreds of the alarms and log events displayed on the screens. In this Paper, a novel hardware circuit collects the important intrusion detection sensors, such as open door, motion alarm camera, passive infrared, microwave, and glass breakage sensors, in addition to fire detectors, which are distributed in the vital areas. V.A. sensors will be connected to the controller 2085 for controlling the signaling of the alarms received during intrusion and fire cases. In this work, hardware electronic circuits and software embedded programs will be introduced to control the generated alarms received from the intrusion detection sensors located at the vital areas. Software by C Embedded/C Arduino will be used for programming the ESP32-S2 internal chip of the 2085 controller. The program will determine the most important location to control the action of the alarm that has been generated from this region and give the highest priority of their sensors to be displayed immediately at the operators alarms log events monitors, according to the order of priority. If an alarm is generated from the security and safety sensors, the 2085 controller will arrange the priorities for displaying immediate alarms on the main alarms screen. Live streaming images from the nearest camera located in this area will be displayed. The C Arduino program permits signal receiving from the intrusion detection sensors at the vital areas as a priority level according to the sensors classification and categorization. The controller system will classify the sensors and determine the highest priority degree and or level of the generated alarms inside the vital areas. Fast action will be taken immediately and easily.
