Decommissioning of nuclear facilities is a multifaceted process in which safety considerations are paramount, both during planning and execution of operations. This also encompasses the ALARA (As Low As Reasonably Achievable) principle, which mandates maintaining the minimum reasonably achievable radiation dose to personnel during the performance of radiation-hazardous operations. Numerous technological procedures employed for dismantling and decontamination of such facilities are conducted under conditions of elevated radiation and industrial hazards. In certain instances, safety justifications for specific operations must rely on computational results obtained through simulation modeling environments, including application of facility information models and virtual reality (VR) technologies.
This paper provides a comprehensive overview of prominent foreign and national software platforms designed to develop simulation models for the technological operations involved in dismantling structures and equipment at nuclear energy facilities during their decommissioning phase.
This paper examines the evolution of relevant tools, from personnel dose load calculations to the application of comprehensive software platforms for multivariate simulation modeling that accounts for radiation, temporal, spatial, kinematic, and economic factors. It details the technical features and illustrates the practical applications of each reviewed solution. The critical role of simulation modeling technologies in enhancing the safety and operational efficiency of decommissioning processes is underscored.
