India has an ambitious programme to expand the nuclear power capacity to 60 GWe by 2032 and 655 GWe by 2050. Such an exponential growth of nuclear power generation warranty identification of suitable sites for nuclear power reactors. Perhaps the 6000 km long vast coastline is the best choice for siting new NPPs because of ready availability of sea water and a quiet seismic environment. Large inland areas with adequate water resources provide additional locations to cater the power requirements of Central and Northern India. In this perspective, the potentials of Deccan Volcanic Province (DVP) for siting new NPPs is discussed. Five zones delineated as safer sites of nuclear power plants on Deccan Trap, are the first hand targets identified by this study. Two of them are situated to the north of Narmada-Son Lineament and have large areas. Chambal and Betwa river systems of Ganga Basin are perennial source of water along with several dams constructed on their course. The other three zones are located to the south of Narmada-Son Lineament and are small in size. The Konkan Coastal Lineament (N-S) in the west and Kurduwadi Lineament (NW-SE) in the east are major tectonic features bordering these zones. The Godavari and Krishna rivers are perennial water sources. Presence of reservoirs within the delineated zones stands advantageous considering their potential as ultimate heat sinks. All the five zones are devoid of any known major seismicity. Thick basalt cover provides good foundation conditions and engineerability for these zones. Considering above characteristics, proposed five zones could be good candidate sites for future NPPs, after their detailed geotechnical investigations. © Director, AMD, DAE, Govt. of India. Source

In India Nuclear Power Plants are constructed as per the guide lines laid by IAEA and AERB. Before concrete is poured into reactor building pits, they are systematically mapped and lithostructural maps are prepared for pit base and side walls. The constraints noticed are carefully attended with geotechnical solutions and remedies to make foundation safe for the entire period of reactor life. Similarly, pit of Kaiga Reactor Building II was systematically mapped for circular base and side walls. Geo-engineering solutions like scrapping out loose, foliated schistose patches, scooping out soft altered zones, filling with grouting, rock-bolting rock segments with major joints and fractures for stopping seepage points were suggested. © Director, AMD, DAE, Govt. of India.

Remote sensing imageries and seismotectonic maps were studied in the light of recently published regional gravity data jointly by NGRI, OIL, GSI and SOI (2006) for accessing the structural fabric of the area to locate suitable site for nuclear power plant. Entire analysis of the data sets has been carried out in Geographical Information Systems (GIS) environment. The study area, Rawatbhata falls well within the Vindhyan Basin bounded by the towns Bundi in the north, chittaurgarh in the west, Jhalwar in the southeast and Kota in the northeast. Interpretation of the arcuate shaped gravity low in the southeast reveals the probable extension of Hindoli Group of Rocks below the Vidhyans and Traps. The selected location is sitting on the gravity high. A gravity gradient of 5 mGal is observed within the 10km buffer zone which is marked in yellow on all the maps. Earlier workers interpreted the thickness of the Vindhyan sediments as 6-7km, based on the deep seismic and gravity surveys, conducted along the Kunjer-Nagaur transect. Study of the seismotectonic maps published by GSI doesn't indicate any seismic activity over the decades. NE-SW trending neotectonic faults and few thermal springs are noticed far away from the study area around 100km N W of Great Boundary Fault (GBF). Numbers of NE-SW, NW-SE trending major and minor lineaments/faults are present in the region. However, analysis of the geophysical data sets doesn't reflect any such lineaments/faults within 25 km radius. Integrated study of the area helped in evaluating the existing nuclear power plant site. © Director, AMD, DAE, Govt. of India. Source

The low order seismic disturbances have led to formation of fractures which have been retained within the soil column along the dry Kantli river course. The study of quaternary semi-consolidated fluvial sediments along the river course in Kaire and Guhala areas indicates mesoscopic displacement of the soil laminae/beds along the fracture. There is also development of fractures without major displacement. The conjugate fractures having an obtuse angle observed in this area depict maximum extension bisecting the obtuse angles horizontally. The observed fracture patterns are having a trend concurrent with the major structural trend depicted by remote sensing imagery. These features depicted in the sand/soil column owe their origin to seismic disturbances during neotectonic activities. © Director, AMD, DAE, Govt. of India. Source
