全球首个三代、四代核电技术耦合项目，开建！

Core Viewpoint - The Jiangsu Xuwei Nuclear Energy Heating and Power Generation Project represents a significant shift in China's nuclear energy strategy, transitioning from primarily electricity generation to a multi-faceted energy supply model that includes industrial steam provision for the petrochemical industry [1][3]. Group 1: Project Overview - The Jiangsu Xuwei Project is the world's first large-scale coupling project of nuclear energy and petrochemicals, officially commencing construction with the concrete pouring of Unit 1 on January 16 [1]. - The project is part of the China National Nuclear Corporation (CNNC) and is located in the Lianyungang Xuwei New Area, featuring plans for two "Hualong One" reactors and one high-temperature gas-cooled reactor [3]. Group 2: Industrial Steam Supply - Upon completion, the project is expected to supply 32.5 million tons of industrial steam annually to the petrochemical industrial park, with a maximum steam demand projected at 13,000 tons per hour by 2030 [2][3]. - The project aims to provide high-quality steam to meet the needs of the petrochemical industry while reducing overall energy consumption and environmental pollution [3]. Group 3: Energy Production and Environmental Impact - The project is anticipated to generate over 11.5 billion kilowatt-hours of electricity annually, which will reduce the consumption of standard coal by 7.26 million tons and cut carbon dioxide emissions by 19.6 million tons, supporting the green transformation of the petrochemical industry in the Yangtze River Delta [4]. Group 4: Technological Innovation - The project integrates third-generation and fourth-generation nuclear technologies, specifically coupling the "Hualong One" pressurized water reactor with a high-temperature gas-cooled reactor, enhancing the efficiency of steam production [6][8]. - The "Hualong One" reactor produces 6,382 tons of steam per hour at 284 degrees Celsius, while the high-temperature gas-cooled reactor generates 2,142 tons of steam per hour at 541 degrees Celsius, allowing for a dual-function approach to steam heating [7]. Group 5: Economic and Operational Benefits - The coupling of these two technologies results in a larger and more reliable heat supply, with economic advantages over coal heating and a significant reduction in carbon emissions, addressing the decarbonization challenges faced by high-energy-consuming industries [9]. - The operational model of the project sets a precedent for the commercial application of high-temperature gas-cooled reactors, reinforcing China's leadership in fourth-generation nuclear technology and enhancing its international competitiveness in nuclear energy [10].
