Detection and Analysis of Activity Ratio A(~(134)Cs)/A(~(137)Cs) at Different Altitude of the Fuel Rod

More Information
  • Received Date: November 03, 1998
  • Axial distribution of activity ratio A ( 134 Cs)/ A ( 137 Cs) along the fuel rod with different burnup level,irradiation history and cooling time is measured by the γ scanning device. As a comparison, this distribution is calculated by the FCAC code used for the fuel rod failure analysis. The calculated values are in agreement with the measured values within a deviation of 12 %.
