In about 50 years of civil nuclear power, there have been two accidents that have caused a great release of radioactive material and have required large-scale evacuation of contaminated areas – Chernobyl in 1986 and Fukushima in 2011. So several international and national organizations conducted a series of activities aimed to identify the lessons to be learned from these accidents and implemented actions in the field of Emergency Preparedness and Response (EPR) based on these lessons. This paper presents how to decrease risk or their consequences for nuclear power plant (NPP), prevent severe direct health damages, and reduce the risk for occurrence probabilities of stochastic influence on health damages in the rate as it is reasonably reachable. Considering the identified importance of the EPR for an NPP that focuses on main parts of On-site and Off-site emergency, including organization, response roles responsibilities, drills and training, and classification of events if it is alert (1st degree) which including actual or potential substantial degradation of the safety level, the shift supervisor would classify the event, Call Emergency Team, Emergency Response Organization (ERO), and Notify Regulatory body, as well as the Technician of radiation safety, would dispatch monitoring team and evaluate the doses. If it is an On-site emergency (2nd degree) which leads to radioactive material release outside of buildings of the nuclear facility or an Off-site emergency (3rd Degree) that leads to serious radioactive material release to the surroundings of the nuclear facility, the shift supervisor would classify the event, call Emergency Team, notify ERO, Regulatory body and local authorities, also the Technician of radiation safety would take Protective measures dispatch monitoring team and evaluation of doses and the Mobile monitoring group would surround the plant for Evaluation of Radiation consequences.
