All its key parts and materials, like the reactor coolant pumps, squib valves, steam generators, reactor pressure vessel internals, control rod drive mechanisms, large forgings and nuclear-grade welding material, are all domestically designed and manufactured, he said.

The new tech launched Thursday by Alibaba Cloud, the cloud service provider under Alibaba Group, is a special liquid coolant whose function is similar to soaking Alibaba's numerous processors in cool water.

Pool-type low-temperature reactors run under normal pressure and at low temperatures, with water acting as a neutron moderator, coolant and radiation shield, Liu said.

Installation of the third main reactor coolant pump at Fuqing unit 5 of China National Nuclear Corporation's Fuqing nuclear power plant, China's first demonstration nuclear power project using Hualong One technology, took place earlier and all the main equipment of unit 5 is also in place, according to CNNC, the State-owned nuclear power company.

Due to defects in the engine cooling system, coolant may leak, bringing the risk of an engine fire, according to the statement.

The recall by Volvo involves 6,415 imported XC90 models produced between Jan 15, 2015 and May 29, 2016, which may have risks of coolant leaks.
