Plate-type nuclear fuel is extensively employed in small modular reactors, where the incorporation of neutron poisons into fuel elements enhances fuel utilization efficiency. Hafnium (Hf), a commonly used neutron poison, is widely applied in nuclear fuel assemblies. To ensure the operational safety, the accurate quantification of neutron poison content is of great significance. In this study, the detection of Hf was investigated using Prompt Gamma-ray Neutron Activation Analysis (PGNAA). A PGNAA system comprising a D-T neutron generator and a high-purity germanium detector was established to measure Hf plate samples. The system achieved a mass detection limit of 3.89 g for Hf. Furthermore, a Monte Carlo simulation model of the measurement system was developed to calculate the characteristic gamma rays induced by neutron excitation. The calculated results deviate from the experimental measurements by less than 10%, thereby validating the model's reliability. These findings provide both experimental and theoretical support for the application of PGNAA technology in measuring Hf content in nuclear fuel elements.

板状核燃料被广泛应用于小型模块化反应堆。在核燃料元件中引入中子毒物可以实现燃料的高效使用,Hf是一种常见的中子毒物,在该类核燃料组件中应用广泛。为保证核燃料在使用过程中的安全性,对其内部中子毒物含量的精确检测十分重要。本研究利用瞬发伽马中子活化分析(Prompt Gamma-ray Neutron Activation Analysis, PGNAA)技术对Hf元素进行了测量分析,基于D-T中子发生器和高纯锗探测器搭建的PGNAA装置,对Hf板材样品展开测量,结果显示该系统对Hf元素的质量检测限为3.89 g。同时,建立了测量装置的蒙特卡罗模拟模型,计算了中子激发产生的特征伽马射线,计算结果与试验测量结果的偏差小于10%,验证了该模型的有效性。研究结果为将PGNAA技术应用于核燃料元件中Hf元素含量的定量测量提供了依据。

板状核燃料被广泛应用于小型模块化反应堆。在核燃料元件中引入中子毒物可以实现燃料的高效使用,Hf是一种常见的中子毒物,在该类核燃料组件中应用广泛。为保证核燃料在使用过程中的安全性,对其内部中子毒物含量的精确检测十分重要。本研究利用瞬发伽马中子活化分析(Prompt Gamma-ray Neutron Activation Analysis, PGNAA)技术对Hf元素进行了测量分析,基于D-T中子发生器和高纯锗探测器搭建的PGNAA装置,对Hf板材样品展开测量,结果显示该系统对Hf元素的质量检测限为3.89 g。同时,建立了测量装置的蒙特卡罗模拟模型,计算了中子激发产生的特征伽马射线,计算结果与试验测量结果的偏差小于10%,验证了该模型的有效性。研究结果为将PGNAA技术应用于核燃料元件中Hf元素含量的定量测量提供了依据。

Plate-type nuclear fuel is extensively employed in small modular reactors, where the incorporation of neutron poisons into fuel elements enhances fuel utilization efficiency. Hafnium (Hf), a commonly used neutron poison, is widely applied in nuclear fuel assemblies. To ensure the operational safety, the accurate quantification of neutron poison content is of great significance. In this study, the detection of Hf was investigated using Prompt Gamma-ray Neutron Activation Analysis (PGNAA). A PGNAA system comprising a D-T neutron generator and a high-purity germanium detector was established to measure Hf plate samples. The system achieved a mass detection limit of 3.89 g for Hf. Furthermore, a Monte Carlo simulation model of the measurement system was developed to calculate the characteristic gamma rays induced by neutron excitation. The calculated results deviate from the experimental measurements by less than 10%, thereby validating the model's reliability. These findings provide both experimental and theoretical support for the application of PGNAA technology in measuring Hf content in nuclear fuel elements.
