The JAERI/USDOE collaborative program is going on using the FNS facility at JAERI. The phase-III is a new series on
tritium breeding measurements with a totally different experimental arrangement from the previous ones that used a point
neutron source geometry. The new series basically consists of an annular test blanket and a pseudo-line source to investigate
the effect of source spread on the neutronic performance. A concise description is made on the features of the simulated
line source, the test blanket systems for phase-IIIA and -IIIB, measured items, experimental results, and their analysis.
Within the same program, nuclear heating rate, gamma-ray activities and resultant energy releases have been measured to
provide experimental data for safety related issues. A comparative study was also performed among the phase-I, phase-II
and phase-III.
I. Introduction
The JAERI/USDOE collaborative program started
in 1984 with the objectives:
(1) to establish new experimental methods for design
