The second in a series of high-temperature fission product release tests was conducted for 20 min at about 1700/sup 0/C in flowing steam. The test specimen, a 20-cm-long section of an H.B. Robinson fuel rod that had been irradiated to a burnup of 28,000 MWd/t, was heated in an induction furnace mounted in a hot cell. Posttest analyses of the furnace, the thermal gradient tube, filters, and other components of the experimental apparatus showed that about 50% of the /sup 85/Kr, /sup 137/Cs, and /sup 129/I were released from the specimen during the test. In addition, approximately 2% of the /sup 110 m/Ag and /sup 125/Sb along with smaller fractions of several other radionuclides were measured by gamma spectrometery. Spark-source mass spectrometric data from a limited number of samples showed significant releases of fission product tellurium and molybdenum, as well as structural (zirconium and tin) and furnace (primarily tungsten) materials. Metallographic examination of the fuel specimen revealed extensive fractures in the cladding, essentially complete oxidation to ZrO/sub 2/, and evidence of fuel-cladding interaction.
