US NANO Nuclear KRONOS MMR Main Helium Circulator Enters Detailed Design Phase
NANO Nuclear Energy Inc. announced on September 3 that new progress has been made in the development of the main helium circulator for its KRONOS MMR energy system. The engineering collaboration with Howden, a Baker Hughes company, has advanced from preliminary engineering design to the detailed design phase. The main helium circulator is a critical mechanical subsystem of the KRONOS MMR energy system, primarily responsible for driving the helium coolant circulation within the reactor to efficiently transfer heat generated in the core to downstream systems. The performance of this equipment directly affects the reactor's thermal-hydraulic performance, overall efficiency, and long-term operational reliability. According to NANO Nuclear...

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...
