Reactors

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]

Incidents

On 31 May 1993, after 28 months of operation,two steam turbine blades in NAPS-1 malfunctioned causing a major fire. This fire propagated to the ractor's emergency cabling system and with that nearly led to the damage of the reactor core.^[3]
