Functional expansion of achievement analysis system (2)

Japan Nuclear Cycle Development Institute (JNC) has developed FBR achievement analysis system by the end of the last fiscal year, and has been improving it to be capable to assess other power generation systems than FBR, in view of public acceptance. In this study, we conducted a trial analysis on various aspects of other energy systems with an objective of functional expansion of the analysis system to obtain generally agreeable results. Trial analysis was performed on LNG fueled thermal power generation and wind power generation in comparison with FBR systems with large power (1 GW x 50-100 plants) and small (50-200 MW) power output, respectively. The impact of the weight attached to input data and indices on the analysis results was analyzed to get to know the characteristics of this analysis system, and the system was further improved in terms of simplification of the analysis structure and the way to handle pair comparison. Then, we again conducted trial analysis using the improved analysis system, in which indices were weighted assuming several societies with different sense of values. Then we calculated the various aspects of values each energy system would gain in the setting of each society. The results for each of the assumed societies were considered to be qualitatively reasonable, but the need for further discussion on the analysis structure, weighting of indices, etc. was pointed out.
