Defect cluster formation in neutron irradiated SUS316 and JPCA doped with 10B

  • 1. Hokkaido Univ., Sapporo (Japan)

Description

A SUS316 and a JPCA were irradiated at 643, 793 and 873 K to 30 dpa in FFTF(Fast Flux Test Facility)/MOTA(Material Open Test Assembly) during its cycle 11 operation to investigate the effect of high helium generation rate on cavity formation under neutron irradiation. In FFTF/MOTA, (n,α) reaction of boron isotope can produce a large amount of helium atoms in SUS316 and JPCA. In all of temperature conditions, cavities were observed in both alloys with different contents of 10B. In view of number density, size distribution and mean size of cavity in the alloys, the effect of helium generation rate on the nucleation and the growth of cavity is discussed. (author)
