Annual publication of nuclear materials balance for 2011/2012

19 December, 2012

The Office for Nuclear Regulation has today published the annual nuclear material balance.

 Nuclear materials such as uranium and plutonium must be accounted for throughout the UK nuclear industry. Nuclear materials balance figures show the difference between the nuclear material inventory recorded in such accounts and the inventory as measured at periodic physical stock takes.

The 2011/2012 figures conform to the pattern of previous years and do not give rise to concerns over either the safety or security.
