Japan Nuclear Cycle Development lnstitute(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 (50-200MW) 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 settmg 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.

In this study, the FBR achievement analysis system developed last year was improved so that we could perform analysis on other power generation systems and assessment with a view of pubinc acceptance. In order to establish the assessment structure for other systems, competitive energy systems with large power outputs (50-100 plants of 1GW power generation system) and small power outputs (50-200MW) were fixed, and investigated their performances and special features. The usage of systems with small power outputs were intended as; (1)use in isolated islands or remote places, (2)use as district power supply, (3)use as industry owned power plants. From the results, energy balance, energy security, easiness and simplicity, and quality of electric outputs were discussed as new indices, and samples of their assessment structures were shown. Concering public acceptance, relating factors were extracted from existing research on it. Especially, about sence of safety and trustworthiness, research on social psychological analysis on them were investigated, so that we showed the assessment structure of risk perception. The assessment structures shown in this study would be able to be applied to assessments of both large power generation systems and small ones, as far as the usages were restricted to the three cases mentioned above. Considerations to extract other indices would be necessary in order to expand the intended usage.

In this study, the general assessment system developed last year was improved so that we could perform multi-sided comparison and evaluation between FBR cycle reactor models quantitatively and objectively. At first, we developed multi-sided evaluation system written in VBA. And then many processes (calculation of coefficients for utility functions, analysis by MUF, and pair comparison, etc.) could be performed on a Personal Computer with simple operation. And the following fuctions were also added in the system; consideration of uncertainty in design data on evaluated results, estimation of the potential of FBR, the absolute evaluation method to get over the weakness of AHP, and so on. Moreover, a concept of comparison with compact reactors and the way of including a new evaluation item, public acceptance, in the evaluation structure are discussed. Although it is important to consider public acceptance for introduction of FBR, it was not included in the assessment structure of the previous study. In this study, we pointed out that public acceptance as a new assessment item of the FBR cycles evaluation system should be included. Ideas to include the item in the system in phase 2 were also discussed. Due to the improvement of the system in this study, we believe that the FBR cycle's evaluation system is becoming more sophisticated than the previous version.

In order to promote the FDR development, it is necessary to see various benefits brought by introduction of FBR from multiple perspectives and have agood grasp of such benefits quantitatively and an adequate R&D investment scale which corresponds with them. In this study, the structured prototype in the previous study was improved to be able to perform cost-benefit analysis. An example of improvement made in the system is addition of subroutine used for comparison between new energy and benefits brought by introduction of FBR with special emphasis on addition of logic for analyzing externality about the new energy. Other improvement examples are modification of the Conventiona1 Year Expense Ratio method of power generation cost to Average Durable Year Cost method, addition of database function and turning input data into database, and reviewing idea on cost by the type of waste material and price of uranium. The cost-benefit analysis system was also restructured utilizing Microsoft ACCESS so that it should have a data base function. As the result of the improvement mentioned above, we expect that the improved cost-benefit analysis system will have higher generality than the system before; therefore, great deal of benefits brought by application of the system in the future is expected.
