PY - 2020 TI - Nuclear Reactors, their Types and Impact on Safety, Environment and Sustainability towards a Green Future JF - Energy Research Journal VL - 11 IS - 1 DO - 10.3844/erjsp.2020.22.27 UR - https://thescipub.com/abstract/erjsp.2020.22.27 AB - The current world is shifting rapidly towards clean energy sources due to the rapid depletion of fossil fuels. Also, as a solution to the extremely intense growing demand of energy across most of the countries and increasing pollution, nuclear energy is considered as a strategic alternative as it is both clean and does not pollute the environment. When compared with most other conventional sources of energy production currently being used, Nuclear energy emits a minuscule quantity of greenhouse gases and hence is environmentally friendly. In this study, several types of nuclear reactors are compared and with environmental pollution and safety as a deciding parameter. Sustainability of the nuclear reactors, their classification concerning safety and their radiation emissions are also reviewed.
