Data summary report for fission product release test HI-1. [PWR; BWR]
This first in a series of high-temperature fission product release tests was conducted for 30 min at 1400/sup 0/C, with the release taking place into flowing steam. The fuel specimen was a 20-cm-long section of H.B. Robinson fuel rod, irradiated to 28,000 MWd per metric ton (t). After the test, the Zircaloy cladding of the specimen was almost completely oxidized and was quite fragile. The fission product collection system included a thermal gradient tube (700-150/sup 0/C), filters, heated charcoal, and cooled charcoal. Gamma ray analysis of apparatus components and collectors showed that about 2.83% of the /sup 85/Kr and 1.75% of the /sup 137/Cs were released from the fuel. Activation analysis of leach solutions from these components indicated that 2.04% of the /sup 129/I was released. Other analyses revealed small but significant releases of the radionuclides /sup 125/Sb and /sup 106/Ru, and of the elements Br, Rb, Sr, Zr, Ag, Sn, Te, Ba, and La.
