This report summarized the results of the study on the capital cost assessment methods in FY1987 which is one of the economic estimation system for FBR that had been developing from FY1986. In this study, the assessment methods developed in FY1986 were investigated in more detail concentrating on equipments and components peculiar to FBR. Moreover, the Land, Structure and Building which compose the capital cost were modeled to be able to calculate the total capital cost. The results of this study are as follows. (1)Investigation of the assessment model for equipments and components peculiar to FBR The assessment methods for equipments and components peculiar to FBR which extracted in FY1986 were evaluated in more detail. Thus, the cost is assessed as the accumulation of the materials and manufacturing cost of the equipments and components in principle. (2)Land, Structure and Building cost model. The cost assessment model for the FBR buildings was determined based on the cost of the total area of the buildings which estimated in reference to the investigation of the materials of LWR (PWR). On the other hand, the model for the Land and Structures was used as the same model as that of LWR. (3)Trial cost estimation of 1000MW FBR plant. The capital cost of 1000MW FBR plant except some facilities which the materials and specifications are unknown was estimated for trial using both the assessment methods developed in FY1986 and 1987. (4)Preparation of the data base of the economic estimation system for the advanced LWR. With regard to the Advanced PWR and BWR which chose as the subject of the economic estimation for FBR considering the phase of commercial FBR deployment, important improvements and differences from the present LWR design were summarized from the view point of the cost estimation and were prepared for the data base of the Advanced LWR. In the future, the capital cost assessment methods developed in this study will be coded to be easily use and ...
