Chennai: Ask a lay person about nuclear energy and the Kudankulam plant and the chances are the images conjured up will be of two big domes against the backdrop of the Bay of Bengal. Now, in an attempt to demystify working of the plant in Kanyakumari district, a 15-minute film will give the public a glimpse of its interiors for the first time. The film, shot on a 3D camera, will be screened at the soon-to-be open nuclear power gallery at the Tamil Nadu Science and Technology Centre in Kottupuram. The 5,000 sq ft gallery set up at 2.3cr in collaboration with Nuclear Power Corporation of India is likely to open along with one on technologies developed at the Defence Research and Development Organisation (DRDO) and an innovation hub for students. P Iyamperumal, executive director of the centre, said the idea was to dispel fears about nuclear power and radiation. "Centres in Mumbai and Delhi have such galleries. This is the first of its kind in south India," he said. It will have interactive displays on the uses of nuclear energy in of medicine, agriculture and industry. Throug a functioning, small-scale model, students can learn fission and fusion reactions that release energy. A large model of a pressurized water reactor, one of the many in nuclear power plants, will show its functions in an actual plant. A scale model of the world's first nuclear reactor Chicago Pile-I will also be exhibited. Apart from interactive displays about nuclear energy and the work of well-known scientists who have conducted research in the field, it will also have informative digital displays on other conventional and non-conventional method of energy generation, including thermal, hydraulic, solar and wind power. "Both nuclear and DRDO galleries will have a quiz corner where students will be asked 10 questions picked randomly from a set of 600. This is to see if children can understand the information we have displayed," he said. The 80 lakh, 5000 sq ft gallery of the technology developed at DRDO will display scale models of battle tanks like Arjun and Abhay, radars, missiles like BrahMos and Prithvi and other aeronautical systems used in military. Those keen on robotics will have it all at the innovation hub. Set up at an estimated 1 crore, it will displays different embedded systems, electronic gadgets that can be dismantled and a chemistry laboratory. The Kotturpuram centre already has galleries on transport, mathematics, life sciences, ocean sciences and a dinosaur park.
