| Abstract |
The SPS Radiation Monitoring System (SPSRMS) has been designed to measure the ionizing radiation which are generated from the high-energy electron 1.2 GeV. SPSRMS design shall be performed to assure of the adequate performance system in order to prevent the radiation exposure of workers and general public in the synchrotron facility. The research purpose is to evaluate the frequency of failure of real-time radiation monitoring system design that might be happened from the abnormal case which is unable to transfer the important radiation dose continuously. An Event Tree Analysis (ETA) had been approached to evaluate the safety reliability of the SPSRMS which is a method of deducing possibilities and outcomes in a chronological order. This method has been determined the probability of possible negative outcomes that can cause harm and result from the chosen initiating event. The scenario results showed that reliability was increased from 99.71%±19.57% to 99.80%±19.58% (95% confidential level) after adding redundancy in all the devices. The reliability assessment results of SPSRMS are presented.
