Abstract
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) dur ing its cycle 11 operation to investigate the effect of high helium ge neration rate on cavity formation under neutron irradiation. In FFTF/M OTA, (n, alpha) reaction of boron isotope can produce a large amount o f helium atoms in SUS316 and JPCA. In all of temperature conditions, c avities were observed in both alloys with different contens of B-10. I n view of number density, size distribution and mean size of cavity in the alloys, the effect of helium generation rate on the nuclation and the growth of cavity is discussed.
