Just like other nuclear "incidents," the authorities in India claim that the situation is under control and no harmful radiation was leaked, even though it's too hot for the experts to get near the plant.

March 11, 2016 – The 220-MW Kakrapar 1 nuclear plant in India automatically shut down after a leak in its coolant system.

A rupture in the coolant system of one of the nuclear reactors at Kakrapar, Gujarat, on Friday morning forced the authorities to indefinitely shut down the plant. Multiple sources confirmed that there was no harmful, radioactive leakage and the backup safety mechanisms kicked in.

However, it will be a while before experts can actually get close enough to the plant to investigate what went wrong, given the high temperature at the plant.

“Unit 1 of the Kakrapar Atomic Power Station, which was operating at its rated power, had to be shut down about 9 a.m. today, consequent to a small leak in the Primary Heat Transport (PHT) System. The reactor was shut down as per design provisions,” a statement issued by the site director of the plant, Lalit Kumar Jain, said.
