| Looking straight down from the building reveals something else; an intricate spaghetti of buildings and structures, pipe works and roads, clearly created with functionality in mind rather than to attract architectural admiration. | Looking straight down from the building reveals something else; an intricate spaghetti of buildings and structures, pipe works and roads, clearly created with functionality in mind rather than to attract architectural admiration. |

| Add to that the complication of nuclear contamination, which has penetrated deep into the building's concrete and steel structure, and there is no wonder that it will take years before all traces of Sellafield and the UK's nuclear legacy waste have been removed. | Add to that the complication of nuclear contamination, which has penetrated deep into the building's concrete and steel structure, and there is no wonder that it will take years before all traces of Sellafield and the UK's nuclear legacy waste have been removed. |
