Add to dictionary

fissile

[ˈfɪs.aɪl ]

Definition

Context #1 | Adjective

nuclear materials

Fissile materials are capable of sustaining a nuclear fission chain reaction. These materials can be split into smaller parts, releasing a significant amount of energy. They are essential for the operation of nuclear reactors and the development of nuclear weapons.

Synonyms

divisible, nuclear, splittable.

Examples of usage

  • Uranium-235 is a commonly known fissile material.
  • Fissile isotopes are crucial for nuclear energy production.
  • Scientists study fissile materials to improve reactor safety.

Interesting Facts

Science

  • Fissile materials are critical in nuclear reactions, particularly for creating nuclear energy or weapons.
  • Common fissile elements include uranium-235 and plutonium-239, both of which can sustain a chain reaction.
  • In a nuclear reactor, controlled fission of these materials generates heat, which is converted into electricity.

Safety and Regulation

  • Fissile materials are heavily regulated due to their potential for use in nuclear weapons.
  • International treaties, like the Treaty on the Non-Proliferation of Nuclear Weapons, govern the use and distribution of fissile materials.

Pop Culture

  • Fissile materials and their implications have featured in various films and books, often highlighting the ethical dilemmas of nuclear power.
  • The term has been referenced frequently in discussions about energy crises and nuclear disasters in media.

Historical Context

  • The discovery of nuclear fission in 1938 was pivotal, leading to the development of nuclear power and weaponry.
  • The Manhattan Project during World War II focused on creating a bomb using fissile materials, drastically changing global politics.

Origin of 'fissile'

Main points about word origin

  • The word originates from the Latin word 'fissilis', meaning 'capable of being split'.
  • It was first used in the early 20th century, particularly in the context of nuclear physics.

The term 'fissile' originates from the Latin word 'fissilis', which means 'capable of being split'. It was adapted in the context of nuclear science to describe materials that can undergo fission, the process of splitting an atomic nucleus to release energy. The modern usage of 'fissile' in nuclear physics became prominent in the mid-20th century as research on atomic energy and nuclear weapons advanced. The understanding of fissile materials is vital for both power generation and military applications, especially during the Cold War, when nations began to seek more effective nuclear reactions for both peaceful and aggressive purposes. As technology evolved, the significance of identifying and managing fissile materials has become essential for nuclear safety and non-proliferation efforts.
