an average lifetime availability factor of 55.9%. The Canadian technicians designed the life of the plant operations for ~30 years which it did complete its lifetime in 2002. The Nuclear Regulatory Authority (NRA), the owner of the nuclear power plant, extended its lifetime operation to 2012 (later to 2021), and kept 55.7% capacity factor with total energy generation of 137 MW. On 1 August 2021, the Canadian unit, K1, was ceased from its criticality operations and was phased out when it was decommissioning from the national grid system, marking the end of its 50-years of long operational services to the nation. From 1973 to 1979, K1 had an operation factor of 70.1% and between 2006 and 2021, it was at 55.7%. K2 In 2015, Chinese energy contractors became interested in Karachi Nuclear Power Plant – eventually the Pakistani administration and Chinese government signed an energy agreement to construct two Hualong One reactor units at the US$ Bn with each reactor producing 1,100 MW. The K-2 is a pressurized water reactor (PWR) supplied by the China National Nuclear Corporation, and is jointly designed by the engineers of the Pakistan Atomic Energy Commission. On 26 November 2013, Prime Minister Nawaz Sharif ceremonially broke ground on an energy project at the Karachi Nuclear Power Plant for the construction of two reactor units, one consisting the Hualong One and the other is ACPR-1000— both are pressurized water reactor. Construction of the KANUPP-2 begins on 20 August 2015 and the KANUPP-3's construction commenced on 31 May 2016. Both units are near completion and are expected to attain full energy capacity in 2021 and 2022 respectively. According to Dr. Ansar Pervaiz, then Chairman of the Pakistan Atomic Energy Commission, said that Chinese banks have provided $6.5 Bn for this project as loans and the cold testing of the reactor system at the KANUPP-2 was commenced on 9 December 2019. KANUPP-2 was synchronised with the electricity grid on 18 March 2021. The China Zhongyuan Engineering Corporation (CZEC) is currently serving its civil engineering consultant for both reactors. On 2 December 2020, the loading of the nuclear fuel started with the clearance from the Nuclear Regulatory Authority. The criticality operation was successfully commenced on 3 March 2020. On 20 March 2021, the K2 was synchronized with the nation's electricity grid system, with PAEC terming the operation as "Pakistan Day gift" to the nation. On 28 May 2021, the
