Description

New test series such as (i) destructive energy measurement, (ii) Gd2O3-UO2 fuel and (iii) PuO2-UO2 fuel tests are in progress, and the conversion factors were evaluated by conducting the energy deposition calibration tests respectively. The fission numbers and energy deposition per core energy release determined through γ-ray spectrometry are as follows. (1) Destructive energy measurement tests: 6.29 x 1011 f/g·UO2/MWs : 4.25 cal/g·UO2/MWs (2) Gd2O3-UO2 fuel tests a. UO2 fuel : 8.83 x 1011 f/g·UO2/MWs : 5.96 cal/g·UO2/MWs b. Gd2O3-UO2 fuel : 6.94 x 1011 f/g·UO2/MWs : 4.69 cal/g·UO2/MWs (3) PuO2-UO2 fuel tests a. Phase 1 : 3.77 x 1011 f/g·UO2/MWs : 2.55 cal/g·UO2/MWs b. Phase 2 : 3.51 x 1011 f/g·UO2/MWs : 2.37 cal/g·UO2/MWs. In addition, an energy deposition in each test was derived from calculating the core energy release history. The energy deposition determined is useful not only to know the threshold of fuel failure but also to make comparison with that of standard tests. (author)
