For the design verification and licensing of newly pressurized water reactors (PWRs), many integral test facilities were conducted. From the above integral test facilities, the obtained experimental results were adopted in the assessment and development of safety analysis codes. In this study, scaling analysis and design parameters of integral test facilities were summarized from the perspective of scaling method, basic scaling choice, equipment design, test matrix and application. The scaling method is the guideline for establishing scaling ratios of integral test facilities and different scaling methods were proposed. With the basic scaling choices of system pressure, geometrical parameters, working medium and equipment material, the design parameters of equipment were discussed. The test matrix and application of different integral test facilities were compared. This work is expected to sum up experience and provide guidance for the design and application of newly integral test facilities.

为了新压水反应堆（PWR）的设计验证和许可，进行了许多整体测试设施。从上述整体测试设施中，获得的实验结果被用于安全分析代码的评估和开发。本研究从缩放方法、基本缩放选择、设备设计、测试矩阵和应用的角度总结了整体测试设施的缩放分析和设计参数。缩放方法是建立整体测试设施缩放比例的指南，并提出了不同的缩放方法。在系统压力、几何参数、工质和设备材料的基本比例选择的基础上，讨论了设备的设计参数。比较了不同集成测试设备的测试矩阵和应用。该工作有望总结经验，为新建一体化试验设施的设计和应用提供指导。
