Neutron Capture by Uranium-238

238U + 1n → 239U → 239Np → 239Pu

अवलोकन

Uranium-238 captures a neutron to form uranium-239, which beta decays (23.5 min) to neptunium-239, which beta decays (2.36 days) to fissile plutonium-239. This breeding reaction produces more fissile material in fast breeder reactors than is consumed, potentially extending nuclear fuel reserves by a factor of 60.

रोजमर्रा का उदाहरण

In every nuclear reactor, some U-238 converts to Pu-239 by this process, contributing about one-third of the energy produced.

औद्योगिक महत्व

Plutonium breeding is central to the nuclear fuel cycle. Fast breeder reactors like BN-800 in Russia are designed to maximize this conversion.
