A Pakistani nuclear power plant imposed a seven-hour emergency after heavy water leaked from a pipe to the reactor.
Tariq Rashid, a spokesman for the Karachi Nuclear Power Plant, commonly known as KANUPP, said the leakage started around midnight on October 18 during a routine maintenance shutdown.
He said an emergency was imposed immediately after the leak.
The emergency was lifted after the leak was brought under control.
He said no radiation or damage was reported.
The 137-megawatt power plant, which started up in 1972, is located about 24 kilometers west of Karachi, Pakistan's commercial capital and biggest city.
