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...
