A Semi-Qualitative Safety Assessment of the Central Radioactive Waste Management Facility in Tanzania Using Analytical Hierarchical Process

摘要

This study identified normal and abnormal conditions, features, events and processes (FEPs) those potentially influence the integrity and safety of the facility that might originate outside or inside the facility. Four hazards, namely terrorist activity, fire outbreak, floods and human intrusion were selected basing on the following criteria; physical reasonableness, probability of occurrence and potential consequences associated with the occurrence of these FEPs. With the use of Analytical Hierarchy Process (AHP), the FEPs were ranked for prevention and mitigation plan based on the following criteria: occurrence probability, potential impact and prevention/mitigation cost. The results show the terrorist activity as the most dangerous hazard to the facility. Terrorist activity has to be given first priority in risk reduction strategy followed by flood. The next are fire outbreak and human intrusion. The study recommended that the resources should be allocated at first to protect the damage of the central radioactive waste management facility from terrorist activity and flood.
