Discussing the necessity of the nuclear fuel cycle, its future, and issues (costs, pros and cons of the LWR cycle, etc.). The trend toward carbon neutrality will lead to a rush to build nuclear (light water reactor) power plants in many countries. As a result, the price of natural uranium is expected to skyrocket, increasing the need for fast reactor cycle development. It is essential to present to the world the concept of commercialization of fast reactors that combine high safety and economic efficiency, and to proceed with development steadily in order to realize it promptly, without dissipating the technologies for design, construction, operation, and maintenance of fast reactors that Japanese industry and JAEA have accumulated through the development of MONJU and other projects.

Times Cited Count：2 Percentile：16.99(Nuclear Science & Technology)Within JAERI, funds invested in a 45 years study of LWR totaled 4.2 billion dollars (bd) for research and 3.4 bd (34,718 man years) for personnel. The benefits to taxpayers from this JAERI work was estimated to be about 6.3 bd, resulting in a favorable cost benefit ratio of 1.5. JAERI is a national research institute and this figure may be regarded as sufficiently high, and many high risk and complex tasks were completed successfully. Commercialized HTGR hasa retail cost of 0.36 bd a year and the share of JAERI is 0.018 bd a year. Estimate is that after commercialization of FR in 2050, a FR will generate revenue from electricity as high as 1,687 bd during the period from 2050 to 2100 which is greater than that of LWR. However, there is substantial uncertainty in these estimates. To achieve long term INES, it is necessary to develop the sustainable scenarios and the long-term robust NKM, as shown in the present study.

The knowledge takes not only a form of explicit knowledge represented by database and manual and but also a form of tacit knowledge to be kept at personal and community levels. This exposition will treat the aging workforce problem for the populational massess and the Nuclear Knowledge Management (NKM) as a performer of its counterplan, and the worldwide trend of NKM topics reorted at the recent international meetings.
