“…Evaluation results must meet regulatory requirements regarding dose acceptance for workers and the public. To reduce the dose that comes from radiological hazards, the following factors can be taken [26,30,32]: -Time. Time is directly proportionate with dose, so the dose can be effectively reduced by limiting the working time in radiation facilities [33].…”

“…Hazard analysis is carried out by quantifying the probabilities and consequences of the identified hazards. The multiplication between Probability and Consequence represents risk value [7,26]. Korean Occupational Safety and Health Agency (KOSHA) has been assigning the value of probability and consequences using data collected from the U.S. Nuclear Regulatory Commission (NRC) and the International Atomic Energy Agency (IAEA).…”

“…For TRIGA 2000 research reactor, we recommend the use of level of probability, level of radiological and non-radiological consequences, and risk matrix, as shown in Tables 2-5. Since the decommissioning of TRIGA 2000 research reactor is the first decommissioning for Indonesia, and all the hazards (radiological and non-radiological) need to determine the likelihood and consequences level, so we recommend searching from the literature, or experiences during operating conditions [7,26]. The multiplication of probability and consequence gives a four-risk value categorization, which are represented by four different colors.…”

Decommissioning is the final stage of a nuclear reactor. In preparing the decommissioning plan, one of the important elements that need to be considered is safety assessment. During decommissioning, there are many complex tasks to be done where the radiological and non-radiological hazards arise and can significantly affect not only the workers but also the general public and the environment. Indonesia has no experience with nuclear reactor decommissioning, so it is necessary to study various experiences of decommissioning activities in the world. This study proposes a framework to implement the safety assessment on the decommissioning of the TRIGA 2000 research reactor. The framework was developed on desk-based research and analysis. The proposed framework involves the facility and decommissioning activities, hazard identification, hazard analysis, hazard evaluation, hazard or risk control, and independent review.
