Nondestructive Determination of Fuel Burn-up in Xian Pulse Reactor
-
摘要: 介绍了利用γ能谱法无损测定西安脉冲反应堆单棒燃料元件燃耗的方法。该法利用测定裂变产物137Cs的活度,并进行相应的历史跟踪、校正计算、理论分析等得出燃耗值,同时也讨论了其它需要解决的关键技术。Abstract: A method for the nondestructive determination of fuel burn-up in Xian Pulse Reactor (XAPR) by gamma-ray spectroscopy is introduced. This method utilizes the activation data of fission product 137Cs, . irradiation history, correction calculation and theory analysis to calculate the burn-up. Some other key technologies are also discussed in the paper.
