Accident said to damage India's nuclear-powered submarine
According to a report, India's first indigenous nuclear-powered submarine, INS Arihant, suffered major damage in an accident that happened about ten months ago. According to the report, the damage was caused by the water that "rushed in as a hatch on the rear side was left open by mistake." The submarine has been undergoing repairs and clean up at the Ship Building Centre in Visakhapatnam.
The submarine was accepted for service in October 2016. It is powered by a 83 MW pressurized-water reactor, which first reached criticality in 2013.
