Shanghai Nancal Electric Co., Ltd., in collaboration with Shandong Nuclear Power Company Ltd. (SDNP) and Shanghai Nuclear Engineering Research & Design Institute (SNERDI), has been honored with the Second Prize for Science and Technology Progress by the China Nuclear Energy Association (CNEA) for the joint project "Localized R&D and Application of Reactor Coolant Pump (RCP) Drives." The project team successfully developed China's First MV Drive for the Generation III AP1000 Nuclear Power Plant Reactor Coolant Pump with fully independent intellectual property, achieving a breakthrough in core technology localization. This accomplishment is of significant importance for enhancing the safety and reliability of nuclear power. The RCP Drive has been deployed for commercial operation and was included in the National Energy Administration's List of Major Technical Equipment in the Energy Sector in 2024.
The full localization replacement of the Reactor Coolant Pump (RCP) Drives for Unit 2 of SPIC's Haiyang Nuclear Power Plant has been successfully completed, adopting a configuration of “4-operation and 1-standby”. The unit was successfully reconnected to the grid on its first attempt. These RCP Drives were jointly developed by Shandong Nuclear Power Company Ltd. (SDNP), Shanghai Nuclear Engineering Research & Design Institute (SNERDI), and Shanghai Nancal Electric Co., Ltd.
The National Energy Administration officially added the "Non-Energy Three-Generation Nuclear Power Reactor Coolant Pump (RCP) Drive" to its list of major technical equipment in the energy sector. The Non-Energy Three-Generation Nuclear Power AP1000 RCP drive serves as the sole power supply for the motor. Its reliable operation is crucial to the stability, availability, and overall performance of the nuclear power plant. To address the supply chain bottleneck in this critical equipment, Shanghai Nancal Electric, Shandong Nuclear Power and Shanghai nuclear engineering R&D institute collaboratively developed a 10 kV/ 50 Hz input, 6.9 kV/ 60 Hz output, 10,500 kVA rated capacity reactor coolant pump drive. Beyond the energy sector, Nancal has also made significant "first set" strides in industries such as chemicals, mining, and energy storage.
On September 24 at 7:08 PM, the Haiyang Nuclear Power Plant 2 successfully completed its fourth refueling overhaul and achieved grid connection. During this maintenance window, Shandong Nuclear Power, in collaboration with Shanghai Nancal Electric and several institutions, completed the first domestic replacement of the main pump VFD for AP1000 units, enabling them to operate at full capacity for extended periods. This achievement enhances the reliability and economic efficiency of the AP1000 units and marks a significant advancement in China's nuclear technology.
