Quality Control in Fuel Burnup Measurement

This paper introduces the strict quality control in the measurement of reactor fuel burnup in NPIC, in terms of personnel training, improvement and optimization of test scheme, selection and accurate measurement of reagents, and monitor and control of enviroment radiation. It mainly addresses the following aspects: full implementation of management program, use of advanced test and experiment methods, reduce of personnel radiation dose and uncertainty in measured results, increasing the speed and efficiency for sample seperation, and thus ensuring the quality in burnup measurement.
