SIR - Mr Goldsborough (T&A, May 5) appears to have forgotten the incident at Windscale in Cumbria when dismissing the significance of past nuclear disasters.

As a proponent of nuclear energy he and others need to consider the following: The costs of constructing nuclear power plants are vast as well as the colossal expenditure of energy in the building process.

The costs of processing and removing radioactive waste is considerable, to such an extent that nuclear energy will never be economical to generate and will be subsidised by the public.

The energy required to extract uranium is considerable and we would be dependent on its availability.

The generation of electricity is only part of our energy needs, energy supplies are also required for transport, unless all modes are electrified.

When we consider the safety implications in terms of leakages of radioactive material and increased concentration of background radiation, the case for nuclear energy hardly stands.

Alternative strategies are required, namely better utilisation of renewables, bio fuels and clean British coal, together with efficiency measures and reducing our demands for energy.
