According to a statement from the China National Nuclear Corporation (CNNC), a key hot performance test was conducted on Unit 5 of the Fuqing nuclear power plant in Fuzhou, in East China’s Fujian Province, on March 2. The CNNC said it is the world’s first nuclear power project using Hualong One technology, also known as HPR 1000, a third-­generation reactor design developed by China. A total of five nuclear power units adopting HPR 1000 technology are under construction by CNNC in China and other countries.

The hot performance test is designed to increase the temperature of the reactor coolant system to thermal shutdown conditions, through the operation of the main pump and electric heater of the regulator. The program also included a series of commissioning tests and periodic tests on specific test platforms, according to the CNNC release. This stage simulates the various thermal working conditions of the nuclear power plant as much as possible. It verifies whether the reliability and related parameters of the nuclear island and conventional island equipment and systems in the hot state meet the design requirements. Officials said that following the series of tests, the performance was verified to meet design requirements.
