Chennai: India's atomic energy regulator found the pressure tubes and heavy water leakage warning-shutdown systems to be fine in all other pressurised heavy water reactors (PHWR) following the shut down of a Kakrapar Atomic Power Station (KAPS) unit, an official said.

The restarting of the power generation at the unit is up to the owner Nuclear Power Corporation of India Ltd (NPCIL) while the Atomic Energy Regulatory Board (AERB) has to be satisfied as to the cause of the leak and the safety measures. On the morning of March 11, the first reactor at KAPS shut down automatically following leakage of heavy water from its coolant channel. The leak was plugged ten days later.
