radioactivity

Nuclear trains rumbling across UK is a fairly familiar sight these days, but the cream coloured transport 'cabins' hauled in the twighlight hours through towns, cities and countryside conceal the real nuclear cargo - the spent fuel flasks. Because the flasks are generally loaded into their transport cabins at the reactor site, there is seldom any chance to see the flasks themselves. The exception to this is the imported foreign fuel which, having been unloaded at Barrow docks, is transported by rail to Sellafield unprotected by any cabin...

AGR Flask with skip to hold assemblies upright and a pair of Magnox flasks from Japan, with shock absorber collars.

Standard Magnox fuel comes in the form of a rod measuring approximately 1 metre long, 5 centimetres in diameter and weighing between 10-12 kilogrammes. The fuel rod is contained in a casing fabricated from magnesium alloy, hence the name Magnox. Prior to dispatch to Sellafield, and with the 'fins' mechanically removed, the rods are transferred from the power station cooling pond to an open-top fuel skip which is then fitted into the transport flask.
