Review Questions

• How has nuclear technology impacted both energy production and military capabilities since its inception?
  • Nuclear technology has had a profound impact on energy production by providing a powerful alternative to fossil fuels through nuclear reactors that harness fission to generate electricity. At the same time, it has significantly altered military capabilities with the development of nuclear weapons, introducing a new level of destruction and changing the dynamics of global power. The dual-use nature of nuclear technology creates both opportunities for sustainable energy and challenges related to security and proliferation.
• Discuss the ethical considerations associated with the use of nuclear technology in both civilian and military contexts.
  • The use of nuclear technology raises several ethical concerns, particularly regarding safety, environmental impacts, and human health. In civilian contexts, issues such as radioactive waste disposal and the potential for catastrophic accidents highlight moral responsibilities towards current and future generations. In military contexts, the existence of nuclear weapons poses ethical dilemmas around deterrence versus disarmament, as well as the moral implications of using such devastating weapons in conflict.
• Evaluate the long-term implications of advancements in nuclear technology for global energy policies and international relations.
  • Advancements in nuclear technology are likely to reshape global energy policies as countries seek sustainable alternatives to fossil fuels amidst climate change concerns. The increased reliance on nuclear power may foster international cooperation in safety protocols and technology sharing but could also lead to tensions related to proliferation risks. As nations navigate these complexities, the interplay between energy security and geopolitical dynamics will be crucial in determining the future landscape of international relations.
