KANUPP

KANUPP Karachi Nuclear Power Plant is located at Karachi, Sindh, Pakistan.

KANUPP, Karachi is a single unit CANDU PHWR with a total gross capacity of 137 MW. It is located at Paradise Point on the arid Arabian Sea Coast, about 15 miles to the west of Karachi. The Shaheed Zulfiqar Ali Bhutto Established of Karachi Nuclear Plant November 28,1972. KANUPP is part of Karachi Nuclear Power Complex (KNPC) and is owned and operated by Pakistan Atomic Energy Commission (PAEC).

The KANUPP reactor site is on the Arabian Sea coast, about 11 miles (17.7 km) west of Karachi.

The Karachi Nuclear Power Plant (KANUPP) has a heavy water moderated and cooled natural uranium fuelled, horizontal pressure tube reactor. Other distinguishing features are once-through, on-power bidirectional fuelling, reactor shutdown by moderator dump, and a reactor building designed for total containment of any pressure or activity resulting from a credible accident. The gross plant rating is 137 MWe and the corresponding net output is 125 MWe. The Reactor Building contains the entire reactor system and auxiliaries, and consists of a pre-stressed concrete cylindrical wall, a hemispherical segmental dome of pre-stressed concrete, and a concrete base slab. The Turbine Building houses the turbine-generator and auxiliaries, some process water equipment, electrical distribution equipment, and the control room. The building is a reinforced concrete frame and block structure. The reactor consists of a tubed calandria vessel of austenitic stainless steel, which contains the heavy water moderator / reflector and 208 coolant tube assemblies. The moderator system consists of the calandria, coolers, pumps and purification system in the heavy water circuit, and control valves, dump valves and helium blowers in the helium circuit. The fuel is natural uranium in the form of sintered uranium dioxide pellets sheathed in thin zirconium alloy tubes to form solid fuel elements about 19.1 inches (48.53 cm) long by 0.6 inches (1.4 cm) diameter. KANUPP came into commercial operation in 1972 and after completing its 30 years of design life it was shutdown on December 06,2002. At present the plant is undergoing several safety up gradations for operation beyond design life. On the request of KANUPP, PNRA allowed the plant to operate at 50 MW for the interim period.
