The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

Various oxidation states of plutonium in solution. At room temperature, pure plutonium is silvery in color but gains a tarnish when oxidized. [34] The element displays four common ionic oxidation states in aqueous solution and one rare one: [18] Pu(III), as Pu 3+ (blue lavender) Pu(IV), as Pu 4+ (yellow brown) Pu(V), as PuO + 2 (light pink ...

The film was shown twice at the 2006 Toronto International Film Festival under the title The Half Life of Timofey Berezin before being distributed by HBO Films under its original working title. Pu-239 is the chemical symbol for plutonium-239 ( 239 Pu), the most readily fissile isotope of the element plutonium .
Plutonium-239 is the primary fissile isotope used for the production of nuclear weapons, although uranium-235 is also used for that purpose. Plutonium-239 is also one of the three main isotopes demonstrated usable as fuel in thermal spectrum nuclear reactors, along with uranium-235 and uranium-233. Plutonium-239 has a half-life of 24,110 years. [1]

Given the right conditions—high enough density, temperature, and duration—bootstrapping results in a chain reaction, burning outward from the center. This is known as ignition, which fuses a significant portion of the fuel and releases large amounts of energy. [20] As of 1998, most ICF experiments had used laser drivers.
