SYSTEMATIC MEASUREMENT OF NEUTRON ACTIVATION CROSS SECTION AT ENERGY RANGE FROM 13.3 TO 15.0 MEV USING FNS FACILITYJapan Atomic Energy Research Institute Tokai-mura, Ibaraki-ken, 319-11 Japan Koji Oishi Institute of Technology, Shimizu Corporation Koto-ku, Tokyo 135 Japan Kiyoshi Kawade, Hiroshi Yamamoto, and Toshio Katoh Nagoya University, Chikusa-ku, Nagoya, Aichi-ken 464 Japan A hundred and forty neutron activation cross sections at energy range from 13.3 to 15.0 Mev have been measured systematically at FNS facility for various structural materials of fusion reactor. The large body of data measured on the unified experimental condition allow the significant improvement of data accuracy requied in many applications. Several dosimetry reaction cross sections based on the present data gave consistent results in the blanket integral experiment. It was proved that the present measurement could provide more reliable database for the formulation of systematic trend for principal reactions in comparison with data previousely reported in literatures.
