摘要
采用在线检测方法对现役核电站燃料棒的破损情况进行监测可以克服传统化学取样方法不能连续探测和不能及时报告堆内燃料破损情况的不足。本工作研制出核电站燃料棒破损在线探测系统(FDDS1),通过检测一回路核燃料裂变产物的活度,根据燃料破损性状分析程序FUDAC1计算出燃料棒的破损根数等参数,给出在线探测报告。
The on-line detection of fuel rod failure in nuclear power plant (NPP) can overcome the disadvantage of traditional chemical sampling method that could not monitor continuously and could not predict in time when rod failure occurred. An on-line detecting system (FDDS-1) for the failure rods in NPP was developed. By detecting the γ activities of fission products in the primary loop of NPP, the FDDS-1 could give the on-line analysis report of rod failure situation by the FUDAC-1 code.
