Abstract

The effluents discharged from the power plants and factories into streams, rivers, lakes and oceans cause physio-chemical and biological changes in the sources. It leads to increase in the surface temperature of the water sources, which ultimately affects the native flora and fauna of that particular area1. Thermal Remote Sensing is one of the best tool for deriving the Land Surface Temperature (LST) and Sea Surface Temperature (SST) and its spatial and temporal variations. The present study focused on LST and SST temperature variations for Pre and Post operations of Kudankulam Nuclear Power Plant (KKNPP) located in Tirunelveli districts of Tamil Nadu, India through Remote Sensing and GIS. For this analysis, thermal data from Landsat ETM+ 2001, 2010, December 2014, 2015 of January, February and March have been freely downloaded and utilized for LST and SST analysis. However, only SST has been concentrated more on this present study. KKNPP’s commercial operation was started on 31 December 2014, therefore, pre operational satellite data sets such as 2001 and 2010 have been used for the LST changes and correlation study with post operational data of December 2014, 2015 January, February and March. The results obtained from pre operational data mainly indicates the temperature variation pertaining to land use land cover change type and there was no much of variations in the Sea Surface Temperature. LST and SST ranges varies for 2001 and 2010 (9.91-28.35C; 2001, 21.32-33.02: 2010) Further, post operational data have been analyzed and resulted with huge variations in SST with increasing trend of about 5 to 7°C. Based on visual interpretation, it is observed that the hot water released in to the sea are clearly seen over an area of 3 to 5 sq km. SST for the period of 2014, 2015 January, February and March shows gradual increases in temperature, however the weather data for that particular period from the nearby station shows not much variations in the maximum temperature range. This pilot study around KKNPP suggest that the area requires suitable remedies to minimize the hot water being released in the sea to protect the ecosystem.
