Why the govt. is so keen on new nukes
The Atomic Weapons Establishment (www.awe.co.uk) has been advertising for tritium processing specialists since before the official decision to build a new generation of nuclear weapons. (Check out their web site and many of the previous editions of "New Scientist".)
Tritium is absolutely required for advanced nuclear weapons but it decays with a 12.3 year half-life. So the bombs require constant topping up. Tritium is made by exposing lithium to a large neutron flux - i.e. in nuclear reactors.
The new generation of nuclear "power" plants are required as tritium factories.
It is no coincidence that the decision to build a new generation of nuclear reactors was announced less than a week after the announcement of the decision to build the new generation of nuclear bombs.
The higher electricity price of nuclear power and waste managment problems are simply disguised subsidies for the MOD.
