摘要: 小型模块化超临界水冷堆（SCW-SMR）是超临界水冷堆（SCWR）与小型模块化反应堆（SMR）的有机融合，可兼具二者的优势，既具有独立的市场需求，也为大型百万千瓦级超临界水冷堆的工程实践提供了基础。本文介绍了SCW-SMR的研发背景、国际主要研发动态、技术特点和优势，提出了研发过程的一些思考，包括总体设计原则、主要设计要求、具体设计考虑和研发阶段建议，供后续研发参考。

Abstract: Supercritical Water-cooled Small Modular Reactors (SCW-SMR) is a fusion of Supercritical Water-cooled Reactor (SCWR) and Small Modular Reactor (SMR). SCW-SMR could have both the advantages of SCWR and SMR, which have independent market demands and could provide basis for the engineering practice of the million-kilowatt SCWR. This article introduces SCW-SMR's R&D background, main international R&D developments, technical characteristics and advantages, and puts forward some thoughts on the R&D process, including overall design principles, main design requirements, specific design considerations, and R&D stage recommendations for subsequent R&D reference.
