However, he said the situation in that country was evolving and the Atomic Energy Commission and its departments were undertaking a detailed review.
Menon said the Atomic Energy Commission and its other agencies "tell us that our designs are different and we also store our spent fuel differently."
"The fire (in Japan) was a hydrogen fire in the area where the spent fuel is stored...They (AEC) tell us is that this is most unlikely," Menon said when asked about the safety of nuclear installations in the country and if they can withstand natural calamities such as tsunamis.
He said the atomic agencies were undertaking a detailed review of the design, the procedures and all the safety features.
"As they learn more about what is happening in Japan, they will continue to review and then they will come back with suggestion for improvement, if necessary," he said.
However, Menon was quick to point out that the situation in Japan was an "evolving situation" and while it is evolving, one should not jump to any conclusion.
