Novel method of nuclear transmutation, which utilizes production of 
-hypernuclei of actinides, will be presented. It may give rise to a new nuclear transmutation mode in which long-lived fission products originating from the heavy fission fragments are not produced at all due to decay of particle in the heavy fragment.

The uncertainty of the lumped fission product (FP) cross section is quantified by using the covariance data given in TENDL-2008 and the low-fidelity covariance (Low-Fi). The relative standard deviations of the one-group capture cross section of the lumped FP are calculated as 4.7% with TENDL-2008 and as 1.5% with Low-Fi. It is found that TENDL-2008 gives larger uncertainty to the FP nuclear data than Low-Fi. In addition, the lumped FP cross sections are calculated with various nuclear data libraries including JENDL and it is found that the largest difference in the one-group capture cross sections among these libraries is 3.8%.

In order to examine the reliability of the JENDL-4 data in application to fast reactor core characteristics analyses, benchmark calculations are planned. As a demonstration test, preliminary benchmark calculations with JENDL/AC-2008 were performed in order to check the effectiveness of some of selected core data in benchmark. From the preliminary benchmark, it is found that validation of cross sections can be effectively carried out with selected core data.

The neutron-nucleus reaction instrument (NNRI) was installed at the J-PARC MLF BL04, which was designed for measuring neutron cross sections with a neutron time-of-flight technique. This includes two kinds of capture 
-ray spectrometers: the 4
Ge spectrometer and the NaI spectrometers. The measurements of neutron capture cross sections for minor actinides and fission products have been started at the NNRI using these spectrometers since 2009. In this paper, the preliminary results and future perspectives are discussed.
