The prevailing meteorological conditions around the site of the proposed Rooppur Nuclear Power Plant have been studied vigorously. The in-depth perusal has revealed the existence of three seasons- Summer, Rainy and Winter with stability classes A, B & A respectively during day and F during the night. The eventual wind speed & direction of the seasons have been observed. Subsequent locations along the dispersion directions have been identified using Google Earth Pro which include highways, educational institution, medical centers, commercial area etc. Dose contours corresponding to a source term equivalent to Chernobyl accident has been created to verify the dispersion direction and perceive the plume arrival time in the designated locations using health physics code HotSpot. Strong dependency of plume arrival time on the stability classes has been observed and lowest values are found for F stability class. Finally, some shelter houses are proposed to accommodate endangered inhabitants during emergency.
