Innovating the Safety Review Pathway to Strengthen the Safety Foundation of High-Temperature Gas-Cooled Reactors — National Nuclear Safety Administration Approves Safety Design Criteria for High-Temperature Gas-Cooled Reactors

Recently, the National Nuclear Safety Administration approved the Safety Design Criteria for the High-Temperature Gas-Cooled Reactor of the Jiangsu Xuwei Nuclear Heating and Power Plant (hereinafter referred to as the Safety Design Criteria). This document further refines the specific safety requirements for high-temperature gas-cooled reactors, provides a foundational basis for the safety design of high-temperature gas-cooled reactors, and serves as an important basis for subsequent safety review. This is China's first approved safety design criteria for small nuclear power reactors (hereinafter referred to as small nuclear power reactors), marking that the safety review of small nuclear power reactors has explored a new pathway led by safety design criteria. I. Relevant Background: The Rapid Development of Small Nuclear Power Reactors Calls for Innovation in Review Methods. In recent years, global advanced nuclear energy technologies have been accelerating their evolution...

Hiconics Signs Contract for Main Helium Circulator Variable Frequency Drive Project at Xuwei Nuclear Heating and Power Generation Plant

Recently, Hiconics signed a contract for the main helium circulator variable frequency drive (VFD) project for the high-temperature gas-cooled reactor (HTGR) at the Jiangsu Xuwei Nuclear Heating and Power Plant, and will supply multiple sets of HC2000W four-quadrant water-cooled high-voltage VFDs for the project. This marks the second application of Hiconics' VFD technology in drive scenarios for key equipment related to Generation IV nuclear power, following the HTGR demonstration project at Huaneng Shandong Shidao Bay Nuclear Power Plant. The Jiangsu Xuwei Nuclear Heating and Power Generation Project is a comprehensive nuclear energy utilization project that adopts a coordinated operation model of "nuclear reactor – turbine generator unit – heating system," focusing primarily on industrial heating while also supplying electricity. Phase I of the project plans to construct two Hualong One pressurized water reactors and one HTR-PM600S high-temperature gas-cooled reactor...
