S13、操作人员重复步骤S11~S12的操作,即可将具有不同铀密度值的标准核燃料板分别放置于各个搁置架上;S13, the operator repeats the operations of steps S11-S12, and then the standard nuclear fuel plates with different uranium density values can be placed on each shelf respectively;
S14、操作人员打开伺服电机20,伺服电机20带动丝杆转动,滑块22沿着丝杆向后运动,当位于喇叭形缺口内的标准核燃料板24进入到探头26与准直孔所形成的区域后,操作人员关闭伺服电机20;S14. The operator turns on the
S15、操作人员打开屏蔽盖驱动电机11,屏蔽盖驱动电机11带动活动屏蔽盖12转动一定角度,到位后关闭屏蔽盖驱动电机11,此时γ射线放射源8放射出的γ射线穿过标准核燃料板24,此时探测器7接收透射到标准核燃料板24下方的透射γ射线数量,随后探测器7将透射γ射线数量转换成电信号传递给上位机;S15. The operator opens the shielding
S16、操作人员打开电机13,电机13带动标准板搁置盘15转动一定角度,标准板搁置盘15将其上的第二个标准核燃料板转运到喇叭形缺口处,重复步骤S15的步骤,探测器7将第二个标准核燃料板所对应的透射γ射线数量转换成电信号并传递给上位机;S16, the operator turns on the
S17、重复步骤S16的操作多次,即可在上位机中得到不同铀密度值的标准核燃料板与透射γ射线数量的对应关系,以此关系为基础利用最小二乘法拟合出透射γ射线数量值与铀密度值的关系式,且拟合出映射关系式,从而最终实现了标准核燃料板的标定;S17. Repeat the operation of step S16 several times to obtain the corresponding relationship between the standard nuclear fuel plates with different uranium density values and the number of transmitted γ-rays in the host computer. Based on this relationship, the least squares method is used to fit the number of transmitted γ-rays. The relationship between the value and the uranium density value, and the mapping relationship is fitted, so that the calibration of the standard nuclear fuel plate is finally realized;
S2、待检测核燃料板铀密度值的检测,其具体步骤为:S2. The specific steps for the detection of the uranium density value of the nuclear fuel plate to be detected are:
S21、操作人员控制伺服电机20反转,伺服电机20带动丝杆反转,滑块22沿着丝杆向前运动,当探头26与准直孔所形成区域处于进料辊道输送装置1的滚筒23和出料辊道输送装置3的滚筒23之间时,操作人员关闭伺服电机20;S21, the operator controls the

The operator places the nuclear fuel plate to be inspected on the
S24、操作人员重复步骤S23即可连续的多个待检测核燃料板的铀密度值进行检测,相比传统检测时,需要消耗大量时间工装定位待检测核燃料板,该检测装置极大的缩短了检测时间,同时实现了连续进行检测,极大的提高了核燃料板铀密度值的检测效率。S24. The operator can repeat step S23 to continuously detect the uranium density values of the nuclear fuel plates to be detected. Compared with the traditional detection, it takes a lot of time to position the nuclear fuel plates to be detected. The detection device greatly shortens the detection time. At the same time, continuous detection is realized, which greatly improves the detection efficiency of the uranium density value of the nuclear fuel plate.
