The Chashma Nuclear Power Plant (Chassnupp) consists of a 300 MW PWR in operation since 2000 by CNNC. A second reactor will be built until 2010.

Chashma-1 and Chashma-II are based on a Chinese prototype reactor that was built in 1990. Owing to serious design faults China decided not to build any more for itself. Instead, it first sold one copy, and now a second, to Pakistan. The original Chinese reactor (at Qinshan) suffered an accident in 1998 causing it to be shut down for a year. China could not fix the problem and hired a US company to complete the repairs at a cost of tens of millions of dollars.

The plant near Islamabad is a replication of CNNC's first NPP Quinshan-1. Given the significant participation of foreign enterprises in supplying main components for Quinshan-1:MHI made the PRV, Germany's KSB the MCPs, Framatome the incore instrumentaion - western officials questioned the CNNCs capability to supply Pakistan without their aid.

Pakistan agreed to buy its second Chinese-made nuclear power plant in May 2004. The reactor will apparently be built in less than seven years, with some reports suggesting it could start operating by 2010.
The Water and Power Development Authority (Wapda) has to buy the electricity produced in Chassnupp. In 2003 Wapda complained publicly that it was being forced to pay almost twice what it should for electricity generated through Chassnupp-1. In 2002-2003 the first unit remained out of operation for nearly 175 days. In one instance, it took authorities 33 days to repair a breakdown.


The China Fulaerji Heavy Mechanical Corp. (Cfhmgc) has been awarded the job of manufacturing the reactor pressure vessel for 300-MW Chashma Nuclear Power Plant (Chasnupp), which has been designed by Shanghai Nuclear Engineering Research & Design Institute (Snerdi) with full participation by engineers from the Pakistan Atomic Energy Commission (PAEC), says the PAEC's 1993-94 annual report.
A PAEC senior official told reporters at a recent briefing at Chasnupp that Chinese industry has been asked to manufacture the vessel after potential suppliers elsewhere refused. Chinese industry is undertaking the manufacture of a commercial reactor pressure vessel for the first time; the vessel for the Chasnupp reference plant, Qinshan-1, was made by Mitsubishi Heavy Industries.


Chinese engineers and industry have started manufacturing the pressure vessel for the 300-MW Chasma reactor being built in Pakistan, a senior official of the Pakistan Atomic Energy Commission (PAEC) said November 21.
Weighing 215 tons and measuring 11 meters in length and 3,75m in diameter, the pressure vessel will be the second heaviest equipment in the plant. The SGs weigh 230 tons. According to the work schedule released when first concrete was poured in August 1993, pressure vessel installation is scheduled for September 1996, fuel loading is to be completed in five months starting in June 1998, and the plant is due for commissioning by the end of 1998.
The 184-ton dome was welded and aligned on a platform near the nuclear island in two parts and placed on the 60-m high containment building by a 600-ton polar crane.
China Nuclear Energy Industry Corp. will supply fuel for the first three cores and help Pakistan set up a fuel fabrication plant. The core will comprise 121 assemblies with 204 fuel rods per assembly, with an active fuel length of 2,9 m. Pakistan is already manufacturing fuel for the 137-MW Kanupp pressurized heavy water reactor at Karachi, at its facility at Kundian near Mianwali, near Chashma.


China has begun negotiations with the South Korean industry to supply the RPV for the plant, because China is not able to manufacture the RPV on schedule. US, France Germany and japan will not supply nuclear equipment to Pakistan because pkistan does not accept full-scope IAEA safeguards and maintains an unsafeguarded HEU production.
But Korea seeks to join the Nuclear Suppliers Group;Korea's Mempbership in NSG wohl close an imueortant loophole in the global export control & prevent Korea to supply Pakistan.
