Hot tests completed at Pakistani nuclear power plant

KARACHI: The 1,100MW K2 reactor at the Karachi Nuclear Power Plant (Kanupp), the first unit using China’s homegrown ‘Hualong One’ technology, has successfully completed its thermal testing also known as hot functional tests (HTFs).

China is building two Hualong One reactors with a capacity of 1,100MW each at the Karachi Nuclear Power Complex on the coast of the metropolis where a single 137MW reactor unit (Kanupp-1) has been operating since 1972.

The construction of the Kanupp-2 and Kanupp-3 reactor units started in August 2015 and May 2016, with the start of commercial operations scheduled for 2021 and 2022 respectively.

Reactor units will have a design life of 60 years and account for approximately 10% of the country’s total generation capacity.

China Global Television Network (CGTN) reported that the outer containment dome of the K3 unit at Kannup was successfully installed on August 31 and the main structure of the nuclear power plant had been completed.

“The HFTs play a significant role in the construction of the nuclear power project, simulating the actual operation conditions of the nuclear power plant to verify the reliability of the main equipment and systems under the thermal conditions, before the nuclear reactor is loaded with nuclear fuel.” the China National Nuclear Corporation said on Sunday.

“The success has laid a solid foundation for subsequent major processes, including nuclear fuel loading and grid-connected power generation,” it added.

“It is also a comprehensive inspection on the quality of the reactor coolant system equipment, pipeline sealing and welding, as well as the design, manufacture and installation of relevant systems.”

The Hualong One technology, also known as HPR1000, is one of the third-generation nuclear power designs with the highest acceptability in the current nuclear power market, and a significant landmark achievement of China’s innovative development of nuclear power.

Currently, six units at home and abroad powered by Hualong One technology are under construction, whose “safety and quality are well controlled”.
