Abstract

Laser induced fluorescence (LIF) is characterized as a non-insertion and whole-field measuring technology, which is commonly used in the thermal–hydraulic experiments. The conventional method for LIF technology is performed on the basis of the theoretical correlations for the fluorescence. A new method for the LIF base on the calibration tests and empirical fitted polynomial was proposed. The mock refueling water tank and mock reactor pressure vessel (RPV) were employed to verify the new method. The precise comparison between the conventional method and new method was carried out. The results indicated that the deviation in temperature measurement was within 0.5 °C for the improved method, and it was within 1.0 °C for the conventional method. The concentration measurement error was within 5.67 % for the improved method, and it was about 7.10 % for the conventional method. The improvement in measurement accuracy brought by new methods of great importance for the thermal–hydraulic experiments.

激光诱导荧光技术在温度和浓度测量方面的改进和验证

激光诱导荧光（LIF）是一种非插入式全场测量技术，常用于热-水力实验。激光诱导荧光技术的传统方法以荧光理论相关性为基础。我们提出了一种基于校准测试和经验拟合多项式的 LIF 新方法。模拟燃料水箱和模拟反应堆压力容器（RPV）被用来验证新方法。对传统方法和新方法进行了精确比较。结果表明，改进方法的温度测量误差在 0.5 °C 以内，而传统方法的误差在 1.0 °C 以内。改进方法的浓度测量误差在 5.67 % 以内，而传统方法的误差约为 7.10 %。新方法提高了测量精度，对热-水实验具有重要意义。

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
