This is hot enough to emit black-body radiation in the X-ray spectrum. This takes about a millionth of a second (a microsecond), by which time the core and tamper of the bomb have expanded to plasma several meters in diameter with a temperature of tens of millions of degrees Celsius. The charged fragments' high electric charge causes many inelastic collisions with nearby atoms, and these fragments remain trapped inside the bomb's uranium pit and tamper until their motion is converted into heat. This initial kinetic energy is 67 TJ/kg, imparting an initial speed of about 12,000 kilometers per second. The remaining 93% is kinetic energy (or energy of motion) of the charged fission fragments, flying away from each other mutually repelled by the positive charge of their protons (38 for strontium, 54 for xenon). Only 7% of this is gamma radiation and kinetic energy of fission neutrons. The immediate energy release per atom is about 180 million electron volts (MeV) i.e., 74 TJ/kg.

The following equation shows one possible split, namely into strontium-95 ( 95Sr), xenon-139 ( 139Xe), and two neutrons (n), plus energy: 235 U + n ⟶ 95 S r + 139 X e + 2 n + 180 M e V The U-235 nucleus can split in many ways, provided the atomic numbers add up to 92 and the atomic masses add to 236 (uranium plus the extra neutron). Fission can be self-sustaining because it produces more neutrons of the speed required to cause new fissions.

When a free neutron hits the nucleus of a fissile atom like uranium-235 ( 235U), the uranium nucleus splits into two smaller nuclei called fission fragments, plus more neutrons. The following explanation uses rounded numbers and approximations. To understand how nuclear weapons are designed, it is useful to know the important similarities and differences between fission and fusion. In some ways, fission and fusion are opposite and complementary reactions, but the particulars are unique for each. Both reactions generate roughly a million times more energy than comparable chemical reactions, making nuclear bombs a million times more powerful than non-nuclear bombs, which a French patent claimed in May 1939. Nuclear fusion combines together lighter atoms to form heavier atoms. Nuclear fission separates or splits heavier atoms to form lighter atoms.

Effects and estimated megadeaths of explosions.

Practitioners however favor the terms nuclear and thermonuclear, respectively. In early news accounts, pure fission weapons were called atomic bombs or A-bombs and weapons involving fusion were called hydrogen bombs or H-bombs. Most known innovations in nuclear weapon design originated in the United States, although some were later developed independently by other states. Large industrial states with well-developed nuclear arsenals have two-stage thermonuclear weapons, which are the most compact, scalable, and cost effective option once the necessary technical base and industrial infrastructure are built. Pure fission weapons historically have been the first type to be built by new nuclear powers. Such weapons would produce far less radioactive byproducts than current designs, although they would release huge numbers of neutrons. Ī fourth type, pure fusion weapons, is a purely theoretical possibility. This process affords potential yields up to hundreds of times those of fission weapons. This sets in motion a sequence of events which results in a thermonuclear, or fusion, burn. Its detonation causes it to shine intensely with x-radiation, which illuminates and implodes the second stage filled with a large quantity of fusion fuel. The first stage is always a boosted fission weapon as above.

staged thermonuclear weapons are essentially arrangements of two or more 'stages', most usually two.

Boosting can more than double the weapon's fission energy yield. boosted fission weapons improve on the implosion design using small quantities of fusion fuel to enhance the fission chain reaction.pure fission weapons, the simplest and least technically demanding, were the first nuclear weapons built and have so far been the only type ever used in an act of war (over wartime Japan).There are three existing basic design types: Nuclear weapon designs are physical, chemical, and engineering arrangements that cause the physics package of a nuclear weapon to detonate. Here the Gadget device is prepared for the first nuclear test: Trinity.

The first nuclear explosive devices, cumbersome and inefficient, provided the basic design building blocks of all future weapons.
