Karachi Nuclear Power Plant (KANUPP)

Karachi Nuclear Power Plant (KANUPP)

Karachi Nuclear Power Plant (KANUPP), Pakistan’s first nuclear plant, is undergoing a 2.2GW capacity extension with two pressurized water reactor units of Chinese design (PWR, Hualong 1).

This historical power plant has been in service with a single 137MW reactor unit (Kanupp-1) since 1972. It is owned and operated by Pakistan Atomic Energy Commission (PAEC).

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

Dextra Griptec coupler was selected for the connection of steel rebars to reinforce the reactor’s concrete shell, designed to successfully withstand an aircraft crash (APC).

More than 1 million units of Griptec standard, position, and transition couplers, mainly in diameter 40mm, have been delivered.

Griptec is well-known for its reliability and performance in tension, compression, and fatigue, thanks to the unique design of the product that complies with the world’s most stringent projects specifications, especially for nuclear reactor building construction.
