Times Cited Count：11 Percentile：59.28(Nuclear Science & Technology)For the purpose to confirm the reliability of the front steering concept, tests of the front steering launcher mock-up and neutron irradiation tests of bearings for a movable mirror were carried out under the ITER conditions. The max. stress of the flexible pipes for the movable mirror was measuerd to be 60MPa, much less than the allowable stress and agree with the calculation. No degradation on the performance of bearings was obtained for the assumed fluence of ITER. The mock-up of remote steering(RS) launcher was tested and RF radiation of 0.5MW-3sec and 0.2MW-10sec over 0-10
were performed. No degradation was obseved, either. The new launcher which has the capability of wider range rf beam steering and the corrugated square waveguide with four miter bends that yield the dog-legged structure has been designed, based on the test results. It has been fabricating for high power experiments.

National Institute for Agro-Environmental Sciences, Japan, established new Free-Air CO Enrichment (FACE) facilities for paddy rice in central Japan (Tsukuba FACE) in April, 2010. Early FACE studies were originally designed to investigate changes in plant growth, crop yield, and carbon cycle under elevated CO and temperature. In addition to these research agenda, a three-year project at Tsukuba FACE that assesses the changes in nitrogen cycle due to climate manipulation (FACE-N) started in April, 2010. The FACE-N project has the following themes: (1) atmosphere-paddy exchange of nitrogen; (2) nitrogen-related processes in a soil-rice system; and (3) development of the sophisticated nitrogen cycling model at a plot scale and of the regional nitrogen assessment system using remote-sensing technique and geographic information system (GIS).

We have been conducting nuclear fuel transportation accident drills jointly with fire agencies since 2002. The purpose of these drills is to improve the capabilities to respond to nuclear fuel transportation accidents. By devising practical drills, we were able to strengthen our partnership with the fire agencies. We have also contributed to fire agencies improving their capabilities to respond to nuclear fuel transportation accidents. This report describes our efforts to improve accident response capabilities, including the details of the drill.
