A Nuclear Weapons Center is a facility dedicated to the research, development, and maintenance of nuclear weapons. These centers are often part of a country's defense strategy, ensuring that nuclear arsenals are safe, secure, and effective. They may also focus on non-proliferation efforts, aiming to prevent the spread of nuclear weapons to other nations. In the United States, the Los Alamos National Laboratory and the Lawrence Livermore National Laboratory are examples of such centers. They conduct scientific studies and simulations to enhance the understanding of nuclear physics and improve weapon designs while adhering to international treaties on nuclear arms control.
