Times Cited Count：6 Percentile：41.74(Materials Science, Multidisciplinary)The oxide layer on the 12Cr steel, HCM12A, is investigated using a scanning probe microscope (SPM), which was formed in lead bismuth eutectic (LBE) at 450
500
C, during 5500 hrs. Hitherto oxide formation mechanisms were studied from viewpoints of the location of original base metal surface, the pass for oxygen travel and Fe diffusion to understand the stability of oxide layer. The new findings in this research are that surface potential measurement detected the boundary between (FeCr)
O
and FeO, which is not found at the topographic mode measurement. The spinel layer can be distinguished from the bulk area with lower surface potential profile, but near the boundary between the spinel and magnetite layers the surface potential profile seems to be continuous except for the narrow path corresponding to the boundary line. The band structure penetrating magnetite and spinel layer was found, which was not found at the topography.

In-Vessel Observations (IVO) techniques for Sodium cooled Fast Reactors (SFRs) are important in confirming its safety and integrity. In order to secure the reliability of IVO techniques, it was necessary to demonstrate the performance under the actual reactor environment with high temperature, high radiation dose and remained sodium. During the investigation of an incident occurred in Joyo, the following observation systems were specifically developed for Joyo. And the following two observations were conducted. (1) Simple overhead observation using a standard video camera for the top of the sub-assemblies and the in-vessel storage rack (2) Narrow space observation using remote handling device equipped with radiation-resistant fiberscope for the bottom face of the upper core structure. As a result, the observations under the actual reactor environment were successfully made even in the narrow space in the reactor vessel and the results provided useful information on incident investigations and planning of restoration work.

The frequency of single strand breaks (SSBs) occurring on both strands of the pBR322 plasmid DNA region flanked by a pair of primers used for polymerase chain reaction (PCR) amplifications was determined after irradiation with 
Cs 
-rays. We refined that real time PCR is suitable for the detection and quantitative analysis of SSBs caused by -ray irradiation. The utility of this approach was also supported by the comparison of the practical experimental data with the Monte Carlo simulation. The potential application of this PCR method for the detection of genomic DNA damage was also confirmed.

Development of a fuel-efficient car is indispensable for the growth of the sustainable mobility society. We have carried out the visualization of the lubricating oil in a car engine and the measurement of the residual stress using neutron beam in order to reduce the friction and weight. We succeeded the high-speed visualization of the lubrication oil in the high-speed running engines by the high-frame-rate neutron radiography technique. We also measured the residual stress in the cylinder head at every material and made a database.

We are investigating the applications of spintronics devices in atomic fields. We reported the Tolerance of spin-Seebeck thermoelectricity against heavy swift ion irradiation previously. The tolerance of spin-Seebeck thermoelectricity against gamma ray irradiation will be reported at this conference. The spin thermoelectric properties after gamma ray irradiation up to 1MGy at room temperature and at 150C will be reported.
