Mumbai, Nov 30: The Nuclear Power Corporation of India maintained it's stand that there was no release of radioactivity in and outside the Kaiga Power Plant and said it is only a drinking water cooler that was contaminated.
NPCIL Chairman and Managing Director S K Jain in a statement said, "Preliminary inquiry does not reveal any violation of operating procedures or radioactivity releases or security breach. It is possibly an act of mischief. The related agencies are investigating."
Around 55 workers suffered minor nuclear radiation exposure after drinking contaminated water from the water cooler in the premises of the plant.
"All plant systems are working normally and cannot cause any contamination. The source of radiation contamination was identified to be a water cooler located outside the reactor building and has been isolated and put out of service," he said.
"No worker is hospitalised and all are carrying their duties," Jain said.
"The contamination detected in this incident has been brought down quickly and currently only one worker is close to the limit specified by Atomic Energy Regulatory Board," Jain said
"NPCIL has very high level of safety compliance and the limits of regulatory authorities are strictly complied with," Jain said.
