Description

We obtained the ratios of 134Cs/137Cs and 154Eu/137Cs in spent PWR fuels with gamma scanning equipment of irradiated material examination facility. The fuel segments, of which the burn-up is about 40 GWD/MTU and its cooling time is 8.4 years, are prepared in Post Irradiated Examination Facility and transported to IMEF. By considering of multi-peaks of 134Cs and 154Eu, we obtained the relative efficiency of the gamma scanning system as a function of energy. And finally we obtained the number ratios of radioactive nuclides in 72 fuel pellets, radioactive 134Cs/137Cs and 154Eu/137Cs. (author). 4 refs., 27 tabs., 28 figs
