न्युक्लीयर भट्टीमध्ये नियामक (जड जल) हा का वापरला जातो ? In nuclear reactors, why is moderator (heavy water) used ?
(a)न्युक्लीयर भट्टी थंड करण्यासाठी / To cool the nuclear reactor
(b)न्युट्रॉनची ऊर्जा वाढविण्यासाठी / To enhance the energy of neutrons
(c)न्युट्रॉनची ऊर्जा कमी होऊन त्याचा वेग मंद व्हावा, आणि त्याचे प्रग्रहण व्हावे म्हणून / To reduce the energy and hence the speed of neutron so that it slows down and gets captured
In nuclear reactors, heavy water acts as a moderator to slow down fast-moving neutrons so that they can effectively sustain the fission chain reaction.
