Research paper thumbnail of Fusion Neutronics Benchmark Experiment on Structural and Advanced Blanket Materials - Leakage Gamma-ray Spectrum Measurement

Some discrepancies between measured and calculated spectra were observed. However, the C/E values for the energy multiplied integral spectrum show that all of the nuclear data files were fairly reliable.

Research paper thumbnail of Tritium Measurements for 6Li-Enriched Li2TiO3 Breeding Blanket Experiments with D-T Neutrons

Pellets of enriched Li2TiO3 with a diameter of 12 mm and a thickness of 2 mm were used as detectors inside the tritium breeding layer. After irradiation, the pellets were dissolved and the tritium activity in the sample solution was measured by liquid scintillation counting. The experimentally obtained tritium production profile in the lithium titanate layer agreed well with MCNP calculations within the estimated error range of the experimental values (10%). Tritium loss from the pellet during storage time at room temperature, a few days, was experimentally found to be negligible.
