As a review of all the nuclear facilities in the country is underway, the authorities are factoring in the lessons learnt from the Fukushima episode and even beyond to ensure that the atomic installations are able to weather all the possible disasters. The upgrade in safety features of the nuclear plants will apply to the existing ones as well as the new ones, including the proposed Jaitapur plants. The factors being taken into consideration include high intensity earthquake, tsunami that would trigger waves upto 15 metres, hurricane and floods, officials said. The four task forces set up after the Japanese incident went into the safety features of the existing nuclear plants to see what can be done to upgrade these and incorporate these in the new ones. The first task force studied Tarapur Atomic Plant (TAP) I and II, the second went into Rajasthan Atomic Plant (RAP) I and II, the third examined the Madras Atomic Plant (MAP) I and II while the fourth studied rest of the reactors, the officials said. pti
