Abstract: According to The IAEA International Nuclear Event Scale (INES) the most devastating (INES Level-7) nuclear accident occurred at Chernobyl Nuclear power plant (NPP),USSR (April 26, 1986) and Fukushima Daiichi NPP, japan, (March 11, 2011) which has causes a great damages on life’s, properties and more importantly it convulses people trust on nuclear energy. Radiological impact from these two nuclear accidents is analyzed in this study. Atmospheric release of radionuclides and maximum radionuclides concentrations in air, rain water, biological material, drink water (tap water) and soil were observed based on distance and continent from the NPPs after the Chernobyl and Fukushima Nuclear power plant Accident. Most of the radioactivity releases from both accidents were noble gases, iodine, cesium, and tellurium.  The amount of refractory elements emitted from the Fukushima accident was approximately four orders lower in magnitude than the Chernobyl accident. After comparison on various issues how the laws and regulation have modified or changed (in some cases) by IAEA and other legislator organization including respective government are also observed. The main purpose of this paper is to analyze the lessons learn, implement the changes and abide by the guidelines to other currently used and under construction power plants. It must have to do to increase their safety and minimize the risk of future catastrophes. Finally our inherent objective is as Bangladesh is a newly emerged country in nuclear energy sector, lesson from these two power plant accident might help to remain more careful and keep surveillance on every sector including operation and maintenance of the plant to increase its safety and become a successful nuclear plant operating country.
