The plant houses two reactors, each a pressurized heavy-water reactor (PHWR) capable of producing 220 MW of electricity. Commercial operation of NAPS-1 began on 1 January 1991, NAPS-2 on 1 July 1992.[2]
The reactors were not originally under IAEA safeguards.[3] but subsequent to the signing of the 1-2-3 agreement, they have been placed under IAEA monitoring[4] with effect from 2014.[5]

31 May 1993 after 28 months of operation two steam turbine blades in NAPS-1 malfunctioned causing a major fire. This in combination with problems in the reactor's cabling system nearly led to a nuclear meltdown.[3]
