Description: The International Atomic Energy Agency (IAEA) Fundamental Safety Principles [6] establish that: “The fundamental safety objective is to protect people and the environment from harmful effects of ionizing radiation”. In Nuclear power plant (NPP), Defence in depth is provided by an appropriate combination of measures, one of which is “Adequate site selection and the incorporation of good design and engineering features providing safety margins, diversity and redundancy. To apply this principle, it is required that the suitability of a site for a nuclear installation be evaluated with regard to the effects of external events that may affect its safety, which could be of natural origin or human induced. Meteorology is the scientific study of the atmosphere that focuses on weather processes and forecasting. Meteorological phenomena can cause several hazards that singly or in combination could affect the structures, systems and components important to safety on a nuclear installation site. The extreme values of meteorological variables and rare meteorological phenomena shall be investigated for the site of any installation. Extreme Values of Meteorological Phenomena: Include the values of wind, precipitation, snow, temperature and storm surges shall be documented for an appropriate period of time, and The output of the evaluation shall be described in a way suitable for design purposes, such as a probability of exceedance relevant to design parameters. Onsite Measurement Programme, Requirement & Data Presentation, Meteorology Data, Joint Frequency Distributions of Data, Annual average Atmosphere Diffusion Factor (X/Q)k with Codes, Consequence Analysis, Major Assumptions, Radiological Dispersion Estimation for Containment & Environmental Atmospheric, and Radiological Dispersions Modeling, were also discussed in this presentation.
