Fuqing Unit 6 Begins CI Equipment Installation
On the afternoon of September 1st, one out of two of Fuqing Unit 6’s primary CI cranes was put in place and prepared for equipment installation. The milestone signifies that Unit 6 is now entering the CI equipment installation phase.
First Moisture Separator Reheater for HPR1000 Shipped from Dongfang Electric
On the morning of September 2nd, China’s self-developed and first of a kind Moisture Separator Reheater (MSR) for the HPR1000 was shipped from Dongfang Electric’s plant in Guangzhou. It was projected to arrive at the Fuqing site in seven days. The MSR removes moisture and reheats the steam to avoid erosion corrosion in the low-pressure turbine. At the same time, it distributes the load of the low-pressure cylinder reasonably and reduce the load of its high-pressure cylinder.
Karachi Unit 3’s RPV installed
On September 5th, Karachi Unit 3, the first HPR1000 export to Pakistan, had its reactor pressure vessel (RPV) installed. Unit 3 is now in the primary equipment installation phase.
China’s First National Standard on Fusion Reactor Structural Material Released
China’s first national standard on neutron radiation resistant structural materials for use in fusion reactors was recently released. The Low-Activated Radiation-Resistant Martensitic Steel for Fusion Reactors (HJB 1016-2018) standard was compiled by the FDS “Fenglin (凤麟)” nuclear energy team at the Institute of Nuclear Energy Safety Technology of Chinese Academy of Sciences. The standard has been put into effect as of September 9th, 2018. The neutron radiation resistant steel is the primary material for advanced reactors like fusion reactors, fusion-fission hybrid reactors, and lead-cooled fast reactors.
