Typical isotopic composition of reactor grade plutonium
The British Magnox reactor, a Generation I gas cooled reactor (GCR) design, can rarely produce a fuel burnup of more than 2-5 GWd/tU. The Magnox reactor design was codenamed PIPPA (Pressurised Pile Producing Power and Plutonium) by the UKAEA to denote the plant's dual commercial (power reactor) and military (production reactor) role. The purity of Pu-239 from discharged magnox reactors is approximately 80%, depending on the burn up value.
