The Chashma Nuclear Power Plant (CHASNUPP) or Chashma Nuclear Power Complex, near Chashma Colony and Kundian town, Mianwali District, Punjab, Pakistan, is a commercial nuclear power plant consisting of four operating units (CHASHNUPP-I, CHASHNUPP-II, CHASHNUPP-III and CHASHNUPP-IV) and one planned unit (CHASHNUPP-V). Chashma Nuclear Power Plant reactors and other facilities are being built and operated by the Pakistan Atomic Energy Commission (PAEC) with Chinese support under the approval and guidelines of International Atomic Energy Agency.
In November 2006, The International Atomic Energy Agency approved an agreement with the Pakistan Atomic Energy Commission for new nuclear power plants to be built in the country with Chinese assistance. The 35-member Board of Governors of the IAEA unanimously approved the safeguards agreement for any future Nuclear Power Plants that Pakistan will be constructing.
On 28 April 2009 a general engineering and design contract for CHASNUPP-3 and CHASNUPP-4 was signed with Shanghai Nuclear Engineering Research and Design Institute (SNERDI). The units will both have generation capacity of 340 MW and a design life of 40 years.On 6 March 2013 the dome of the third reactor was lifted into place.
The 340 MW Unit 3 (CHASNUPP-3) was officially inaugurated on 28 December 2016 by Prime Minister Nawaz Sharif.
CHASHNUPP-4 has been connected to national grid on 29 June, 2017 . Formal inauguration is to be held on 08 September, 2017 by Prime Minister of Pakistan, Shahid Khaqan Abbasi.
The complex has its own training establishment, known as CHASCENT (CHASNUPP Center of Nuclear Training). CHASCENT houses a Full Scope Training Simulator (FSTS) for CHASNUPP-1 and a similar facility for CHASNUPP-2 is under construction. The simulator is used for providing training to the nuclear power plant operators. Apart from training nuclear plant operators the centre offers various engineering programs at diploma and degree levels. The centre is currently in a phase of expansion to cater to an ever-increasing demand for quality technicians and engineers within PAEC.
