Neutron Capture by Uranium-238

238U + 1n → 239U → 239Np → 239Pu

Descripción general

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.

Ejemplo cotidiano

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

Importancia industrial

La crianza de plutonio es fundamental para el ciclo del combustible nuclear. Los reactores reproductores rápidos como el BN-800 de Rusia están diseñados para maximizar la conversión de U-238 en Pu-239.
