Research Evaluation Committee carried out a pre-evaluation of Research and Development of Partitioning and Transmutation Technology of Long-Lived-Nuclides namely, partitioning, nuclear data, reactor physics, fuel, creative transmutation technology, in Aug. 2000. Following results are obtained from the research and development. For example, two extract ant systems, capable of recovering all actinides in spent fuel, were newly nominated in partitioning technology. Also, neutron capture cross sections of 7 nuclides of MA and Fission Products (FP) were determined in nuclear data measurements. Some of those measurements are for the first time in the world. An advanced measurement system of a full solid angle Bi4Ge3O12 detector etc. was developed to measure the energy dependence of the neutron capture cross sections. These achievements in the first phase are summarized in the report to promote the research and development in the second phase effectively.
