Opening

Albert Einsteins theory of Special Relativity gave famous formula E=MC^2 that forms the bedrock of Nuclear fission & fusion to convert mass into Energy

Nuclear FusionNuclear Fission
①Forms by combination①Forms by dissociation
H + neutron → H_2 + reduced massUranium^235 → Thorium + energy
②No radioactive end products②Radioactive end products.
③Naturally occurs in the sun③Artificially created in nuclear reactors
④Tremendous amount of energy④Relatively lower energy

Global Security dilemma:

Body · points and prose

  • Just Energy transition to renewable
  • VS
  • more energy production for development

Nuclear Energy in addressing dilemma: (1) Help create sustainable, endless source of safe, continuous energy (2) Help achieve target of Paris Pact (3) More energy creation can lead to better economic growth - eg IEA → 10% energy output increase → 0.5% GDP growth (4) Help end dependence on fossil fuel → huge source of geopolitical rivalry

ways to tap above

  • more global collaboration like ITER for tokomak tech
  • Safe use of Nuclear under watchful guidance of IAEA

Close · a framework

Above steps would aid in achieving SDG-7 of Clean Energy which is seminal for Sustainable development.
