Hualong One Pressurizer Electric Heaters Achieve Coverage of Two Major Technical Routes
The pressurizer electric heater is an important safety-class component of the reactor coolant system (primary loop) in pressurized water reactor nuclear power plants, directly affecting unit pressure regulation and safe, stable operation. The localized pressurizer electric heater developed by Chuanyi Instrument Co., Ltd., a subsidiary of SINOMACH Instrumentation Group under SINOMACH Group, has been applied to China's self-developed Generation III nuclear power units such as "Hualong One." The photo shows the qualification prototype of the Hualong One pressurizer electric heater. With the batch construction of Hualong One units advancing, units adopting different technical routes have imposed new customized operating condition requirements on pressurizer electric heaters. In October 2019, Chuanyi Instrument, together with China General Nuclear Power Engineering Co., Ltd., initiated the development of the CGN-version Hualong One pressurizer electric heater...

Completion of World's First Domestic CAP1000 50Hz Canned Motor Reactor Coolant Pump for Guangdong Lianjiang Nuclear Power Phase I
Recently, the world's first domestically manufactured CAP1000 50Hz canned motor reactor coolant pump for the Guangdong Lianjiang Nuclear Power Phase I project was successfully completed and ready for shipment. The completion of this equipment marks significant new progress in the independent development and localization of China's Generation III nuclear power core equipment. Harbin Electric Group provided the canned motor for this reactor coolant pump. The Guangdong Lianjiang Nuclear Power Phase I project plans to construct two domestically developed CAP1000 Generation III passive pressurized water reactor units, each with a single-unit capacity of 1.25 million kilowatts. The project is based on the independent CAP1000 Generation III passive nuclear power technology, adopts a seawater secondary circulation cooling scheme, promotes the coordinated development of nuclear power development and coastal ecological protection, and serves the green and low-carbon development needs of the Guangdong-Hong Kong-Macao Greater Bay Area.
