先进反应性测量系统的研发与应用

相比于传统的反应堆控制棒价值测量方法，快速的动态棒价值测量方法要求反应性测量设备具有更高的精度和性能，以准确获取和处理堆外探测器的电流信号，并需通过额外的堆芯中子学计算对试验过程中的空间效应进行修正。为此本研究开发了一套包含先进物理试验测量仪（APTC）和动态棒价值测量软件包（LIGHT）的先进反应性测量系统（SMART），并对SMART开展了一系列验证试验。结果表明，SMART具备完整的物理启动试验功能，其精度和性能能够满足包括动态棒价值测量在内的物理启动试验的要求；在300 MW压水堆核电厂中的成功应用也充分验证了SMART的工程应用能力。 

Development and Application of Advanced Reactivity Measurement System

Comparing with traditional reactor control rod worth measurement methods, the? rapid dynamic rod worth measurement method requires a kind of reactivity measurement equipment with higher accuracy and performance to obtain and deal with the current signal from ex-core detectors, and the spatial effects during the test should be corrected by additional core neutronics calculation, therefore, in this research the Advanced Reactivity Measurement System(SMART) is developed including the advanced physics test computer(APTC) and the dynamic rod worth? measurement code (LIGHT), which can wholly support physics startup tests including the dynamic rod worth measurement test. In addition, a series of verification tests are performed for SMART, and it can be indicated that SMART is capable to complete all the physics startup tests, and the accuracy and performance can satisfy physics startup tests including the dynamic rod worth measurement test. Engineering application capability of SMART is also verified by successful application in 300MW nuclear power plants.
