Sellafield MOX Plant

Sellafield MOX Plant is a fabrication facility operated by Nuclear Decommissioning Authority in United Kingdom. It has a capacity of 120 tHM/yr as of 2001, about 1% of world fabrication capacity.

Recorded because it is the clearest failure in the industry's history. Built to make 120 tonnes of MOX a year, downgraded to 40, and in a decade of operation produced a small fraction of even that before closing in 2011 when its principal customer, Japan, stopped taking deliveries after Fukushima. The United Kingdom still holds the largest separated civil plutonium stockpile in the world and now has no plant that can turn it into fuel.
