RADIOCHEMISTRY OF THE PWR FUEL MATERIAL CYCLING TESTS (WAPD-29-1 AND -2) IN THE WAPD-29 VH-3 LOOP OF THE MATERIALS TESTING REACTOR

The results of in-pile irradiation tests of PWR fuel materials with particular regard to the chemical and radiochemical aspects are reported. These tests were conducted to study the difference of fission product release from defected fuel specimens containing UO/sub 2/ fuel materials of two different specific densities; also, one test included a comparatively high oxygen concentration in the loop water to study the effect of an accidental oxygen addition on the rate of fission product release. No firm deduction could be drawn as to the effect of different fuel densities on the emanation of fission products from defected specimens, and the high oxygen concentration had practically no effect on the rate of fission product release.
