Kudankulam nuclear reactors are safe' The Kudankulam nuclear reactors are designed to be safe against natural calamities like earthquake and tsunami and there is no risk of flooding by sea, a senior official said here Tuesday 15th March, 2011. M. Kasinath Balaji, site director, said the buildings that house the nuclear reactor and auxiliary equipment, reactor safety systems, safety diesel generators and others are designed to operate safely under seismic activity. He said the Kudankulam project, located around 600 km from Chennai, and has been provided with a shore protection bund of 7.5 meters from the mean sea level (MSL). According to him, the design got testified during the 2004 Indian Ocean tsunami that hit the Tamil Nadu coast.
The Nuclear Power Corporation of India Ltd (NPCIL) is building two 1,000 MW nuclear reactors at Kudankulam. The entire equipment is supplied by Russia. According to Balaji, the Kudankulam reactor has the state of art Gen 3 plus safety design features that ensure reactor core is always filled with water containing boron. This would ensure the temperature of water below the limits. He said the reactors are cooled by natural circulation when there is loss of power supply to the re-circulation pumps. According to him, each reactor has four diesel generator sets to supply standby power to keep the reactor cool when it is shut down. He said there is remote possibility of the reactor core melting due to heat. And even if the core melts, there is a special feature known as core melt catcher to contain the damage. According to the Atomic Energy Regulatory Board (AERB) of India, the situation at Japan's nuclear sites after the earthquake and tsunami is being monitored.
