Definition of thermonuclear in English:



  • 1Relating to or using nuclear reactions that occur only at very high temperatures.

    ‘thermonuclear fusion’
    • ‘Since those temperatures generally amount to a few million degrees, fusion reactions are also known as thermonuclear reactions.’
    • ‘Such events include thermonuclear reactions within the sun, interactions between cosmic rays and black-hole-creating star collapses.’
    • ‘Since the thermonuclear fusion of hydrogen within stars gives you helium, some regions of the cosmos could easily accumulate more than their 8 percent share of helium, but, as expected, no one has ever found a galaxy with less.’
    • ‘Fast ignition offers a potentially simpler method to achieve thermonuclear fusion without some of the technical hurdles facing conventional inertial-confinement fusion.’
    • ‘It represents a major step forward for the heavy-ion approach to inertial-confinement fusion, in which small pellets of thermonuclear fuel are compressed to the point of burning by beams of heavy ions.’
    • ‘Deuterium plays a critical role in most thermonuclear fusion reactions.’
    • ‘Most of it is hydrogen-dominated gas or plasma, simple in behavior though bearing the seeds of elemental diversity through thermonuclear reactions in stars.’
    • ‘Plasma physicists recently reported key advances towards sustained thermonuclear fusion in the laboratory.’
    • ‘The line is crossed once it's massive enough to start thermonuclear reactions in the core.’
    • ‘Such a source can be used to drive thermonuclear fusion, to simulate the plasma that are found near the surface of neutron stars, or to produce jets similar to those in astrophysical phenomena.’
    • ‘The physics community's confidence that the obstacles to controlled thermonuclear fusion can be overcome has led to the design of machines that will test physics issues for both routes to controlled fusion.’
    • ‘He said that the sun was essentially a gigantic thermonuclear reactor.’
    • ‘We freely describe the thermonuclear fusion of hydrogen in the centers of stars as burning.’
    • ‘Through a process known as ‘boosting,’ you get a thermonuclear reaction.’
    • ‘From 1957 until his death in 1976, Heisenberg worked on problems in plasma physics and thermonuclear processes.’
    • ‘Mounted in the stern structure of the vessel's central core were four thermonuclear reactors that used water as the reaction mass required to produce the ion streams that propelled the ship.’
    • ‘In the Sun, the process of thermonuclear fusion converts atoms of hydrogen into helium atoms, producing radiant energy.’
    • ‘The issue they discussed was whether intense, short bursts of high powered heavy ion beams could ignite thermonuclear fuel confined by its own inertia so as to produce a net gain of energy.’
    • ‘Thus fusion is a thermonuclear process: one that sustains itself purely by the heat it generates.’
    • ‘Over the Sun's lifetime, the thermonuclear reactions would, according to theory, gradually change the composition of the core of the Sun and alter the Sun's overall physical structure.’
    1. 1.1 Relating to or involving weapons in which explosive force is produced by thermonuclear reactions.
      ‘thermonuclear war’
      • ‘So unless they start testing and I don't think they will, then we have to assume that they don't have the most sophisticated thermonuclear weapons.’
      • ‘When in 1949-50, the Soviet Union made its first nuclear bomb test, Teller pushed for the thermonuclear bomb as part of the U.S. defense program.’
      • ‘By 1960 it was clear that the advent of nuclear weapons, in particular thermonuclear weapons, and ballistic missiles to deliver them, created the potential for a completely new kind of warfare: push-button, nuclear-missile war.’
      • ‘I pointed out that there was surely no safer place on earth than a nuclear bunker designed to withstand a 20-megaton thermonuclear blast.’
      • ‘In February 1956 Eisenhower approved a Joint Chiefs of Staff request for increased production of both very high-yield thermonuclear weapons and small warheads suitable for air defense.’
      • ‘The début Soviet atomic test in 1949 was followed by the first American thermonuclear test in 1952 and a thermonuclear Soviet test in 1953.’
      • ‘Don't worry though, this collision won't occur for another 3 billion years or so, by which time we'll all be long dead, having killed ourselves by much more mundane methods such as biological weapons or global thermonuclear war.’
      • ‘To gain a meaningful nuclear deterrent, a nation doesn't have to threaten the massive thermonuclear response major nuclear powers have been doing for so many years.’
      • ‘It has nuclear bombs, thermonuclear bombs; it has bombers, which are aging somewhat.’
      • ‘The first step in detonating a thermonuclear weapon is to ignite the high explosive that causes a shock wave to travel inward and compress the nuclear material the explosive surrounds, known as the pit.’
      • ‘Its devastating effect is twofold: first, from the heat of the thermonuclear reaction, and second, from the radioactive fallout which continues after the bomb has been deployed.’
      • ‘Rockets, turbines, computers, solid-state electronics, and nuclear and thermonuclear devices were all relatively new to members of the early Cold War generation.’
      • ‘Modern weapons with both fission and fusion stages are called thermonuclear or hydrogen bombs.’
      • ‘What is also known is that the weapons that destroyed these Japanese cities were relatively small in comparison to the destructive forces generated by later testing of thermonuclear weapons.’
      • ‘Fortunately for civilization, none of these conflicts, with the possible exception of the Cuban missile crisis, pushed the world to the abyss of global thermonuclear war.’
      • ‘Fusion creates the power of the thermonuclear or hydrogen bomb.’
      • ‘Fusion bombs, also called thermonuclear bombs, have higher kiloton yields and greater efficiencies than fission bombs.’
      • ‘The successful test of Sakharov's bomb in August 1953 ended America's thermonuclear monopoly and earned the physicist his first medal.’
      • ‘He also remained an outspoken supporter of nuclear power generation, thermonuclear weapon development and stockpiling, and even the use of small nuclear devices for demolition projects and other peaceable purposes.’
      • ‘An intercontinental ballistic missile with a thermonuclear weapon would be deterrent enough.’
      • ‘More than Vietnam, it was the Cuban missile crisis of October 1962 that taught Kennedy vital lessons about the limitations and dangers of expansionism and brinkmanship in a thermonuclear age.’
