India has achieved a major milestone in its nuclear energy programme as the indigenously built Prototype Fast Breeder Reactor (PFBR) at Kalpakkam, Tamil Nadu, has attained criticality. What is Criticality? Criticality refers to the state of a nuclear reactor when it achieves a self-sustaining chain reaction. At this point, each nuclear fission event releases a sufficient number of neutrons to sustain an ongoing series of reactions without external neutron sources. In simple terms, it is the condition where the reactor becomes self-sustaining in nuclear fission reactions. About the Prototype Fast Breeder Reactor (PFBR) The PFBR is an advanced nuclear…
