The Kirana Hills is a small and extensive rocky mountain range located in Sargodha, Pakistan. It is also a place of tourist attraction in Sargodha City. Locally known as "Black Mountains" due to its brownish landscape, its highest peak is about 980 feet (300 m).
Known for its extreme weather conditions, its maximum temperature reaches to 50 °C (122 °F) in the summer while the minimum temperature recorded is as low as freezing point in the winter. Due to its rocky landscape and minerals, a volcanic and geophysical survey was conducted by the Geological Survey of Pakistan. Its environs are heavily infested with wild boars.
Kirana-I was the assigned codename of the 24 subcritical 'cold tests' conducted by Pakistan from 1983–90. The Pakistan Army Corps of Engineers led the civil engineering of potential sites for the tests to be conducted. The Pakistan Atomic Energy Commission (PAEC) carried out several tests of the feasibility of weapon designs; all tests were subcritical (cold) tests and produced no energy blast yield.
Additional studies on the radiation effects of nuclear explosions was also carried out by PAEC. The Kahuta Research Laboratories (KRL) also conducted subcritical tests of its own weapon designs.
