An official at a nuclear power plant in Pakistan says it declared a seven-hour emergency after heavy water leaked out of a reactor during maintenance work.
Tariq Rasheed says Tuesday night's leak did not cause any damage or radiation. He said on Thursday that the plant located in the southern city of Karachi was safe and that the emergency was declared as standard procedure.
He says the plant is scheduled to restart operations in one month.
The Karachi Nuclear Power Plant went on line in 1971 and is currently capable of producing 100 megawatts of electricity. The plant is located on the outskirts of the city.
