A version of the Sellafield Mox Plant – Lessons Learned Review has been released under Freedom of Information legislation.
It sets out the problems during the commissioning and operation of the plant, which shut in 2011, and makes a dozen recommendations to be followed if a new plant is built. The facility was designed to reprocess plutonium to make mixed oxide (Mox) fuel for nuclear reactors. British Nuclear Fuels (BNFL), which then ran Sellafield, believed the plant would make money and boost its reprocessing business.
“As a result, the Sellafield Mox Plant had very significant gaps both in its design and operating capability.
“This meant that the plant was not fit for purpose and struggled from the start with a wide range of operational problems.”
