The computer systems for planning and management of reactor decommissioning were developed for effective implementation of a decommissioning project. The systems are intended to be applied to construction of work breakdown structures and estimation of manpower needs, worker doses, etc. based on the unit productivity and work difficulty factors, which were developed by analyzing the actual data on the JPDR dismantling activities. In addition, information necessary for project planning can be effectively integrated as a graphical form on a computer screen by transferring the data produced by subprograms such as radioactive inventory and dose rate calculation routines among the systems. Expert systems were adopted for modeling a new decommissioning project using production rules by reconstructing work breakdown structures and work specifications. As the results, the systems were characterized by effective modeling of a decommissioning project, project management data estimation based on feedback of past experience, and information integration through the graphical user interface. On the other hands, the systems were validated by comparing the calculated results with the actual manpower needs of the JPDR dismantling activities; it is expected that the systems will be applicable to planning and evaluation of other decommissioning projects.
