The Nuclear Power Corporation of India Limited's (NPCIL) atomic power plant at Kakrapar in South Gujarat was shut down on Friday morning following a leak in its Primary Heat Transport System (PHTS), official sources said.
NPCIL's site director Lalit Kumar Jain said Unit One of the nuclear plant was closed at 9 a.m. after a "small leak" in the PHTS.
"All safety systems (at the plant) are working as intended," Jain said in a statement.
Kakrapar Atomic Power Station (KAPS) comprises two units of pressurised heavy water reactor of 220 MWe each.
Allaying any fears, Jain said: "The radio-activity/radiation levels in the plant premises and outside are normal."
Official and police sources in Tapi district, where the plant is located, meanwhile, echoed Jain's statement that there was no need for panic or evacuation at the plant.
