Development and Improvement of Physical Test Instruments in Nuclear Power Plant

核电厂的物理试验仪器是大修期间监督堆芯参数和反应性的重要工具。本文简要分析了国内核电厂物理试验仪器发展和应用,详细介绍了目前国内外最新试验仪器的研发和改进,改进后的试验仪器不仅具备传统反应性仪和多笔记录仪的功能,还增加了很多传统反应性仪不具备的功能。具有多功能、体积小、功耗低、操作方便、界面友好的特点,明显改进了核电站物理试验的工作方法,极大提高了物理试验的效率,缩短了大修试验的时间,减轻了物理人员的工作量。

Physical test instruments in nuclear power plants are important tools for monitoring core parameters and reativity during overhaul.In this paper,the development and application of physical test instruments for nuclear power plants in China and abroad are briefly introduced.The research and development and improvement of the latest test instruments at home and abroad are introduced in detail.The improved test instruments not only have the functions of traditional reactivity instrument and multi pen recorder,but also add many functions that traditional reactivity instrument does not have.It has the characteristics of multi function,small volume,low power consumption,convenient operation and friendly interface.It obviously improves the working method of physical test in nuclear power plant,greatly improves the efficiency of physical test,shortens the overhaul test time,and reduces the workload of physical personnel.
