A Summary of Benchmark Experiments for Simulation of Fusion Reactors Using an Annular Blanket with a Line Deuterium-Tritium Source

The Japan Atomic Energy Research lnstitute (JAERI)/U.S. Department of Energy collaborative program was performed using the Fusion Neutronics Source facility at JAERI. In Phase III of this program, tritium breeding measurements were conducted in prototypical blankets driven by a simulated deuterium-tritium neutron line source. This phase differed from the earlier two phases in respect to the spatial distribution of the source as the earlier experiments were done with a point neutron source. This series basically consisted of an annular test blanket and a pseudoline source to investigate the effect of source spread on the neutronic performance. A concise description is on the outlines of the simulated line source, the test blanket systems for Phases-IIIA, -IIIB, and -IIIC, measured items, experimental results, and their analyses. 23 refs., 8 figs., 3 tabs.

Overview of the latest experiments under the JAERI/USDOE collaborative program on fusion neutronics

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 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.
