Nuclear power facilities are being industrialized in degrees and cohorts to meet globally power supply demands and to elevate the global economy. Since generation one, a variety of fuels and coolant chemicals have been validated for improved nuclear power plant performance. Nuclear or radioactive materials are utilized in medical sciences to heal life-threatening disorders, in addition to electricity generation. Nuclear power facilities are capable of providing enough electricity to fulfill global demand, but they have lifethreatening side effects, and we face a disaster similar to Chernobyl. In this article, safety measures and techniques in different profile of nuclear power plant are studied. The majority of nuclear disasters occur as a result of human errors and miscalculations, with just a few occurring as a result of plant mechanism failure. Both of these elements are investigated in the essay to raise knowledge about nuclear power plant safety.
