Abstract. Under the ITER R&D Task framework, a series of experimental
measurements and analyses have been conducted at Fusion Neutronics Source
(FNS) Facility at JAERI, on various neutronics issues addressed from the
critical nuclear design of ITER. The experiments comprised items of (1) bulk
shielding of the ITER shield blanket configuration including the
superconducting magnet layer, (2) streaming effects simulating a gap in two
adjacent blanket modules, and (3) nuclear heating and induced radioactivity.
Overall validity of design calculation, consequently, is assured in most
cases by the C/E values. This paper deals with an overview of neutronics
work at FNS/JAERI.
