nuclear

Examples of nuclear in the following topics:

• The Iranian Nuclear Deal

• Nuclear Proliferation

• Nuclear Weapons

  • The proliferation of nuclear weapons, explosive devices which derive force from nuclear reactions, is a key challenge of foreign policy.
  • The proliferation of nuclear weapons, explosive devices which derive their destructive force from nuclear reactions (either fission or a combination of fission and fusion), is an important challenge of foreign policy.
  • By the 1960s, steps were being taken to limit both the proliferation of nuclear weapons to other countries and the environmental effects of nuclear testing.
  • The Partial Test Ban Treaty (1963) restricted all nuclear testing to underground facilities, to prevent contamination from nuclear fallout, while the Nuclear Non-Proliferation Treaty (1968) attempted to place restrictions on the types of activities signatories could participate in, with the goal of allowing the transference of non-military nuclear technology to member countries without fear of proliferation.
  • Identify the history of nuclear weapons and international efforts to regulate them

• Nuclear Size and Density

  • Nuclear size is defined by nuclear radius; nuclear density can be calculated from nuclear size.
  • Nuclear size is defined by nuclear radius, also called rms charge radius.
  • It can be measured by the scattering of electrons by the nucleus and also inferred from the effects of finite nuclear size on electron energy levels as measured in atomic spectra.
  • Nuclear density is the density of the nucleus of an atom, averaging about $4 \cdot 10^{17} \text{kg/}\text{m}^3$.
  • The nuclear density for a typical nucleus can be approximately calculated from the size of the nucleus:

• Binding Energy and Nuclear Forces

  • Nuclear force is the force that is responsible for binding of protons and neutrons into atomic nuclei.
  • The nuclear force is the force between two or more component parts of an atomic nuclei.
  • Nuclear force is responsible for the binding of protons and neutrons into atomic nuclei.
  • Binding energy is the energy used in nuclear power plants and nuclear weapons.
  • These nuclear forces are very weak compared to direct gluon forces ("color forces" or "strong forces") inside nucleons, and the nuclear forces extend over only a few nuclear diameters, falling exponentially with distance.

• The Nuclear Arms Race

  • The nuclear arms race was a competition for supremacy in nuclear warfare between the United States and the Soviet Union during the Cold War.
  • The nuclear arms race was a competition for supremacy in nuclear warfare between the United States, the Soviet Union, and their respective allies during the Cold War .
  • The goal of this assembly was to eliminate the use of all Nuclear weapons.
  • The Soviets' proposal involved universal nuclear disarmament.
  • Summarize the nuclear arms race between the U.S. and the Soviet Union

• Nuclear Weapons

  • A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions—either fission, fusion, or a combination.
  • A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion.
  • Only two nuclear weapons have been used in the course of warfare, both by the United States near the end of World War II.
  • In addition, it is also widely believed that Israel possesses nuclear weapons (though they have not admitted to it).
  • The first nuclear weapons were gravity bombs, such as this "Fat Man" weapon dropped on Nagasaki, Japan.

• Nuclear Fission in Reactors

  • Nuclear reactors convert the thermal energy released from nuclear fission into electricity.
  • Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller (lighter) nuclei.
  • This is known as a nuclear chain reaction.
  • Nuclear safety involves the actions taken to prevent nuclear and radiation accidents or to limit their consequences.
  • An induced nuclear fission event.

• Nuclear Reactors

  • A nuclear reactor is a piece of equipment in which nuclear chain reactions can be harnessed to produce energy in a controlled way.
  • The energy released from nuclear fission can be harnessed to make electricity with a nuclear reactor.
  • A nuclear reactor is a piece of equipment where nuclear chain reactions can be controlled and sustained.
  • However, nuclear reactors produce nuclear waste containing radioactive elements.
  • Describe the nuclear chain reaction process utilized in most nuclear reactors

• Nuclear Fission

  • Nuclear fission occurs when an atom splits into two or more smaller atoms, most often the as the result of neutron bombardment.
  • Nuclear fission is a process by which the nucleus of an atom is split into two or more smaller nuclei, known as fission products.
  • The strong nuclear force is the force between two or more nucleons.
  • In atoms with small nuclei, the strong nuclear force overpowers the electromagnetic force.
  • As the nucleus gets bigger, the electromagnetic force becomes greater than the strong nuclear force.
